DAMAGED SALVAGE CARS

The modern motor vehicle is very efficient at converting the energy held in the petrol into energy that can be used to drive a car. However efficient though it may be only about 75% of the energy in the gasoline is actually converted into motion. The remainder is lost in the form of excess heat. Your vehicle needs a cooling system to remove this heat before it can do damage to the engine. Excess heat also hinders performance and decreases fuel economy.

Some of the heat is vented through the exhaust system as gas. The remainder of the heat has to be removed by the cooling system. The cooling system is a network of holes drilled through the engine through which coolant is pumped. Because calling is a mixture of antifreeze and water it has a high boiling temperature. This means it can get a lot hotter than water normally can without boiling away. Because the coolant is also kept under pressure this to increases the boiling point allowing it to absorb even poor heat.

Once the water has been superheated in the engine it is circulated back to the car radiator. The radiator is there to facilitate heat transfer between cool air flowing in through the front of the car and the superheated water. By spreading the water over a very large number of metal plates in the radiator the surface area is increased exponentially and cooling can take place rapidly because of it.

If the car is moving through a traffic jam or stationery and not much air is entering the engine then there is a problem of overheating. To counter at this a radiator fan in front of the radiator can generate airflow when required. A thermostat is used to turn this feature on and off. The radiator cooling fan is powered by the fan belt and this belt should be checked regularly to make sure you do not overheat.

It’s so easy to make a mistake when buying car parts if you don’t know what you’re doing, many people seemingly make all the right moves and still end up buying a dud product that breaks within a few months or doesn’t work at all. This article is intended to prevent you making that same mistake by answering a few common questions and raising one issue that most of you will never even have considered.

The first problem people have is that they don’t know which batter their vehicle needs, finding this out is actually a lot easier than you might first imagine, simply head to autozone.com, type in the name and brand of your vehicle along with a few other details and viola, they’ll show you exactly what you need. Readers should note that these batteries can range in price from $40 up to around $100, some retailers are cheaper than others but as I’ll explain below, car battery costs can be misleading.

You don’t want to buy from the cheapest provider just for the sake of it; you need to check out what additional service they can provide you, I’d always pay an extra $10-$20 for a free installation. Additionally, you want to purchase from a trustworthy retailer who only deals in fresh batteries, Sears do this very well. Car batteries will not function properly if they remain unused for extended periods of time, e.g. over 6 months, so it’s best to buy them fresh and have them fitted straight away, gas stations are notorious for selling products that have been collecting dust for months on end, avoid these if possible.

That’s it folks, follow my advice and you really shouldn’t run into any problems. If you’re a car nut and want your garage to be in tip top condition you may want to read this guide to garage floors.
