How to prevent your classic car from overheating?
As the thermostat ages, it can fail and remain closed which will cause your car to get very hot…quickly. If your radiator, belts, and hoses are in good repair and the car still overheats, replace the thermostat. Freeze/Core plugs are usually located on one or both the sides of the engine block and are designed to protect it from freezing.
Is it normal for an old car engine to overheat?
Engines are designed to run hot for excellent efficiency, but not to the extent that they overheat and damage components by overpressure or loss of coolant. Some say that overheating engines are the typical shortcomings of older cars and anyone who owns one will eventually be left stuck and steaming on the side of the road.
Why does my car overheat at a traffic light?
The radiator must have air moving across it to carry away the heat, so if you’re on the highway and it stays cool, but at a traffic light it starts to overheat, the issue is usually related to airflow. The next questions you can ask are: do you have the proper cooling fan in place?
Can a bad head gasket cause an engine to overheat?
The ease or difficulty of replacing leaking plugs varies depending on their accessibility. A blown or bad head gasket will cause coolant to leak from your cooling system, and you’ll find the evidence in your engine’s oil or you can find oil in the coolant. Either way, it’s a mess, and the engine will eventually overheat.

How did the Pontiac V-8 engine get cooled?
Beginning with the first production engines in 1955, Pontiac V-8 engines were cooled by reverse flowmeaning the cooling water enters and cools the heads first and then some of the water enters the block and cools the
When did Pontiac stop using reverse flow cooling?
In 1960, Pontiac abandoned the reverse flow system in favor of “conventional” flow where cooling water enters the block first and cools the cylinders — then all the water flows into the heads, cools the valves, and returns via the intake manifold to the radiator.
Why is my Pontiac engine not cooling properly?
As displacement got larger, compression went higher, and engine heat increased to get better performance, it may be that the cylinders were getting inadequate cooling – which would likely not show up on the temp’ gauge but would show up as piston failure in “stressed” engines.
