Over Weight and Over Heating

Over Weight and Over HeatingVehicle weight is a major issue that many Four Wheel Drive owners are often unaware of or just ignore. This is not only a performance issue but also a safety issue and not just for the vehicle owner but also for other road users. At Berrima Diesel Service ( www.berrimadiesel.com.au ) they usually see half a dozen 4WDs in their workshop every day for tuning, performance problems or turbo charging. During the process of their work they weigh the vehicles as part of the job. They do this as they have most vehicles coming in for a power gain. It might end up with the power gain at the wheels, but it may not push the vehicle as thought. This is where the weighing process comes in, sometimes with surprising results. They utilise a modern electronic weighbridge that is accurate to within 10kg. Considering that the average 4WD wagon only has a payload capacity of just over half a tonne, it doesn't take long to swallow that up with 2 or 4 occupants, oils in the engine, diffs, gearbox, fuel in the tank/s, the normal accessories like bull bar, towbar, heavier suspension (big springs and shocks are literally heavier). Even different tyres can weigh substantially more than standard .Generally, the big wagons have a maximum GVM (max loaded weight) of 2.9 tonne to 3.1 tonne. Berrima Diesel see the average ones weighing 2.9 tonne to 3 tonnes and they are certainly not loaded for a trip. When they get the accessorised big wagons in they start to reach towards 3.2 tonnes and they have seen the odd 100 series Landcruiser in their workshop, obviously with a lack of power problem, weighing in at 3.5 tonnes. When you talk troopies, they regularly weigh over their GVM as they are stacked up with all the heavy gear needed for the trip. Large steel fuel tanks not only carry a lot more fuel (weight) but weigh in surprisingly more than the factory poly or tin tank. One recent GU Patrol went over 3 tonne and the vehicle wasn't what you would call heavily modified, just the usual 'steel gear'.A big problem arising from the ever increasing weight of 4WD's is fuel consumption. A standard 4WD diesel can start off with a happy consumption figure of around 10-12 litres/100km only to have it blow out to 16ltres/100km once modified. Tyre blowouts are common on a lot of trips and this is an area that weight can have a huge effect. Standard tyres are designed to work within the working parameters of the vehicle but once it is overweighted the standard tyres are often working very close to their maximum weight limit. Throw in an extremely hot road and the working weight of the tyre gets lower. When considering loading up next time, check the loaded weight of the vehicle and check the combined load rating of the tyres. Make sure you have a good percentage of difference between the tyres and the weight of the 4WD they are carrying. Eg. probably 20% to 30% less weight of the vehicle than the maximum tyre carrying load. Wheel bearings are another thing to consider. Make sure that they are greased if you are carrying weight.Overweight vehicles are the main reason for performance problems. Not only that but they are often illegally overweigh. Ask the people how much they think their 4WD weighs and the general answer is 2.2 tonne or 2.4 tonne. When Berrima Diesel explain that it weighs in at 3 tonne or more they have trouble believing it!! Add to this the 2 tonne trailer and you have, for example, a 3 litre Nissan trying to move a combined weight of 4.5 to 5 tonnes!!Overweight vehicles can also become an insurance issue in the case of an accident. A listed weight, initiated by the accessory manufacturer on accessories, would be of a great benefit to people. Some other areas to consider that can effect vehicle weight areas steel refrigerators, larger tyres, upgraded suspension also lends itself to more weight as well as thicker springs, storage drawers, roof racks, dual batteries, different seats, HF radios. People usually need these for trips but at least an awareness of where the weight is coming from can help with controlling it.Find a reputable weigh bridge or just turn into an RTA truck weigh bridge for free and get ready for a possible shock!Radiators and Air flow:*Consider a larger radiator. Some Factory radiators are a 2 core and can be increased to a 3 core radiator.*Please resist fly screens where possible.*Consider the size and positioning of driving lights, winch, number plates and particularly bull bar air flow.*Check to make sure air conditioning condenser fins are clean!!*If an Intercooler is mounted in front this can add considerably to hot air flow over the radiator and restricting air flow to the radiator.*Consider installing a few small bonnet vents on the left and right of the rear region of the bonnet. This has proven to be a popular addition and has huge effects on under bonnet temperatures. Considering how tight most engine bays are after a few accessories are added, this venting addition can reduce heat stress on a variety of products under the bonnet.Engine set-up:*Over fuelling is usually the major cause of high combustion temperatures.*Make sure the fuel injection system has been thoroughly checked and setup correctly.*If the vehicle is fitted with a turbo or super charger, over fuelling may be the cause. It is very easy to over fuel a diesel once plenty of air is available as possibly no smoke under load may be visible. Visible smoke under load can be a warning of over fuelling!This article and the technical advice was taken from an interview with Andrew Leimroth of Berrima Diesel Service. Andrew is one of The Diesel Experts who have been working exclusively on diesels since 1965. His wealth of knowledge and skill with problem diesels is well known in the automotive industry.

SUV Safety Top Of Mind For Manufacturers

SUV Safety Top Of Mind For Manufacturers

As SUVs continue to be a popular alternative to minivans and station wagons, SUV safety awareness has also increased and has become a prime consideration for consumers when buying these types of vehicles.Though many consumers feel more secure in an SUV, independent vehicle tests show that the size of SUVs, along with higher ground clearance and heavier weight, often makes them less maneuverable than passenger vehicles. Manufacturers are addressing safety concerns with new features. For example, Toyota's Star Safety System offers five safety features as standard equipment on all SUVs-Vehicle Stability Control, Traction Control, Anti-Lock Braking System (ABS), Electronic Brake-Force Distribution (EBD) and Brake Assist. Vehicle Stability Control helps prevent front- and rear-wheel slip, which is a frequent cause of drivers losing control of their vehicles. According to the National Highway Traffic Safety Administration, there is a 67 percent risk reduction in single-vehicle crashes when a stability system is in use. Traction Control helps drivers maintain control on wet, icy and loose or uneven surfaces by applying individual wheel braking and reducing engine output when necessary in those conditions. Anti-Lock Brakes use a computer to monitor wheel speed sensor information. If the computer senses that a wheel is approaching lockup (which can cause skidding and loss of control), ABS sends a signal to reduce, then to reapply brake pressure multiple times per second for as long as you maintain firm pressure on the brake pedal, keeping the wheels from locking.Electronic Brake-Force Distribution optimizes the amount of brake force that's sent to each wheel. For instance, if you have cargo in the back of your vehicle, EBD reapportions brake force, helping to maintain optimal braking at each wheel. Brake Assist applies additional brake pressure so drivers can take full advantage of ABS. Brake Assist sensors detect sudden "panic" braking and apply additional pressure needed to help maximize braking effectiveness. Standard safety features are constantly being developed and implemented into cars, trucks and SUVs. Many are designed specifically to deal with SUV safety issues, while others, like Anti-Lock Brakes, can be found on passenger cars and pickup trucks. Either way, these features are becoming the norm and should be considered when shopping for an SUV.

Trip Preps: Seven Easy Steps To A Safer Road-trip

Okay, youve made the decision: youre going on a cross-country vacation, and instead of renting a car, youll be taking your own. Take these few simple precautions to ensure that your trip is as safe and enjoyable as possible:1) Plan your trip strategically.Doing your homework may not sound very exciting or romantic, but many an adventure has been derailed by lack of planning. Know where youre going, the route you expect to take, and how long it should take you to get there. Travel-related Internet sites and your local AAA can help you to plot a course, find lodging and fuel stations, and avoid construction or heavy traffic. Have a good road atlas and maps in the glove box.2) Make sure that your car is mechanically sound.Before embarking on our trip, make sure that your vehicle is in top condition: engine, cooling systems, brakes, and other vital systems. Check the oil and other fluids before leaving. Lastly, make sure that your tires are in top condition and properly inflated; the experience of having to change a flat tire or wait on the roadside for assistance is not likely to enhance your vacation.3) Be ready for common (and uncommon) roadside emergencies.Forewarned is forearmed. Though it may seem unlikely, proceed as if you expect to get a flat tire or a radiator leak. Pack the standard essential items such as a tire-changing kit (including a spare tire), jumper cables, and road flares. Beyond that, let your imagination roam and prepare for the worstcarry extra windshield wipers, an approved gasoline container, motor oil, elastic tie-downs, or whatever else you could potentially need.4) Carry food and beverages in the car.Even if you plan to stop for meals, it never hurts to have provisions in the car with you. If you break down in an isolated area, youll at least have food and drink to sustain you until help comes.5) Pack a standard first-aid kit.Prepackaged first-aid kits come in a variety of sizes and levels of complexity, and are easy to just stow in your car. Packing your own kit, though, allows you to individualize its contents according to the medical needs of you and your family. Include standard first-aid fare like bandages, antiseptic ointment, an antibacterial cleanser, alcohol, tweezers, and fingernail scissors. For medications, include an analgesic, an anti-diarrheal, a medication for motion sickness, and an antihistamine.6) Make frequent stops.For reasons of health and comfort, its far better to make frequent stops. Individuals who are elderly or suffer from poor circulation should be able to get out of the car and move around briskly, about every 90 minutes if possible. Individuals who arent will still benefit from short, frequent bouts of exercise to relieve the stiffness and discomfort of sitting immobile for extended periods of time.7) When fatigued, stop for the night.Often vacationers try to drive straight through, making as few stops as they can manage. Sure, this may get you to your destination a little more quicklyor it may keep you from arriving at all. Fatigue dulls your senses and slows your reaction time, decreasing your ability to respond quickly and effectively to circumstances. The usual remedies for sleepiness while drivingrolling down the windows, turning up the radio, and drinking caffeinated beveragesonly postpone the inevitable. Stop somewhere for the night, if you can. If necessary, pull over to the side of the road and revive yourself with a short nap. If your bodys trying to tell you that it needs rest, its best to listen.

Car Selling Tips For Ebay Motors

Its no secret that everyday more and more people turn to eBay to buy and sell products online and eBay Motors, the branch of the company created to sell vehicles is no different. I have bought and sold vehicles at eBay Motors and have had some great and some no so great experiences on both sides of the fence but either way it was always learning experience that helped me later on.Obviously if youre trying to sell a car online at eBay Motors youre probably looking for the best possible price. Here are a few tips that you can use to get the best price when selling your car online. First and foremost, you must clean and fully detail your car so that it appears as close to perfect as possible depending on its overall condition and you should never try to conceal any minor flaws. When people are depending on pictures to buy a car they dont want to guess whats under the dirt or try to figure out how bad a flaw really is. Being brutally honest might net you a little less but it will prevent any headaches later on in the dealing process.Never try and skimp on your auction description and pictures. As mentioned earlier, people are buying a car and potentially spending a bunch of cash so if they see anything they dont like they will pass your auction or listing in a heartbeat. It is much better to take as many pictures as possible, a good rule of thumb is to provide as many pictures as you would like to see if you were the buyer. Also post them up as a slideshow or a collage and cover all the angles, dont put up one picture and say email me for more, many people will not go through the trouble of requesting more photos for any mainstream model car.I recommend that you take pictures of the following angles to help the potential car buyer understand what kind of shape your car is in. Keep your pictures flowing around the car to ensure you dont miss anything and it will help the buyer realize that youve covered everything theyre looking for?Start at the drivers side and take a shot at an angle shooting toward the headlight but showing the entire drivers side in the photo then move around the vehicle taking the side, rear, passenger, and then straight on front. Taking the long angles is very helpful to show that your car body is true and doesnt have waves from a bad body job. Be sure to take close ups of any damage or flaws and point them out in your auction or listing description as well. Once youve covered the exterior of the vehicle take clear pictures of the interior including each of the seats, floor mats and under the floor mats, the headliner, and the dashboard. When you take a picture of the dashboard make sure you take a solo shot of the odometer to verify the mileage.Moving on you want to take pictures of the engine compartment which is why it is crucial that it has been detailed nicely. One trick my friend uses that not many people think of is to take the dipstick out and take a close up of the oil to show that is fresh and clean. This might or might not help but the more you show the less hassle youll get in the selling process.Now that you have the exterior, interior and engine covered you will want to add some pictures of the under carriage of your car. This is becoming the more and more the norm when people are looking at used vehicles online, they want to ensure they arent missing anything. To take away all their fears of damage and rust issues you should capture images of the front portion, mid portion and the back portion and make sure you include the muffler, catalytic converter and the wheel wells and any other areas that you feel should be covered. A lot of car enthusiasts will take shots with their wheels off to show the brake rotors or take shots of the shocks and so on but thats up to you. Youll usually see this if the seller is showing that they just changed or upgraded to new parts.The last tip I will recommend is something I think is extremely important for any sale but especially if youre selling a classic or vintage car and that is the cars documents. That is the original owners documents and manual with any repairs and regular maintenance. Also include any preventative maintenance documents like rust proofing or any improvements that youve made since buying the car.Provide your phone number and email so people can call or contact you with questions. If you make sure you answer any email or phone requests promptly and courteously and include whats been outlined above, Im positive youll get the best deal possible for your car without any major problems during the whole car selling process.

Summary

Vehicle weight is a major issue that many Four Wheel Drive owners are often unaware of or just ignore. This is not only a performance issue but also a safety issue and not just for the vehicle owner but also for other road users.
