Nick's Auto Blog

Hello, my name is Nick. This is my new auto blog. Have you ever wondered about how you can improve the look and functioning of your auto? If so you are in the right place. I live in a large house in the suburbs of Melbourne, Australia and my house has as many garage parking spots as it does rooms. And believe me, it has a lot of rooms. I like to collect classic cars and then work on them to restore them to their former glory. In doing this, I have learnt lots of cool tricks. I would like to share some of these tricks with you here.

What Causes Classic Cars To Overheat?

Automotive Blog

Many owners of classic cars have to deal with their car overheating. Some think that adding coolant into the engine will solve the problem but that may be far from the truth. This is because many things apart from a lack of coolant in the engine can cause overheating. This article discusses some of the reasons why your classic car may overheat.

Sediment Build-Up In Radiator Tubes

Water circulates in the radiator tubes so that it is cooled before it re-circulates in the engine. Over time, sediment can accumulate in those tubes and reduce the space available for the water to circulate so that the heat in the water is dissipated in the radiator fins. When that happens, hot water will keep being sent back into the engine and the result is that it will overheat. The solution to this problem is to take your classic car to an auto shop so that the radiator is "rodded out" (rods are pushed into it to dislodge the sediment in there). After this procedure, water will be able to circulate freely again.

Limited Capacity Of The Radiator

Car parts are made with given geographical conditions in mind. If they are used in conditions different from the conditions that were envisaged by the manufacturer, then the part will fail to do its work. For instance, if the radiator in your classic car was designed for cooler climates (like in Germany) and you live in a hot climate (like Australia) then the radiator's capacity will be inadequate for that area. In such a case, you will have to retrofit your classic car with a radiator that has a higher capacity so that the engine can remain cool in the hot weather of your area.

A Defective Water Pump

A water pump forces water to circulate throughout the engine then back to the radiator for cooling. Once that pump weakens and is no longer able to pump effectively, then the rate at which water circulates through the engine will slow down and the engine will overheat. The solution here is to have the water pump checked and replaced if it is defective.

Leaks In The Cooling System

Sometimes an engine may overheat because there is a leak that is decreasing the engine's coolant or water. You can suspect this problem if the level of coolant or water in the radiator keeps dropping after a very short time. You may also see leaked coolant under the car. Have the auto shop conduct a pressure test on the cooling system in order to identify where there is a leak so that it can be fixed.

Not every episode of overheating is because there is no coolant in the classic car. Contact classic car restoration experts like Restocraft Classic Car Restoration to check your car so that the problem is fixed before it destroys your car engine.
