Question about Cars & Trucks
Posted by Anonymous on
The radiator sheds heat at a specific rate. Increasing air flow increases that rate a bit, but even with increased air flow, there is a specific rate.
When you start out, there is a "cold reservoir" in the radiator — without shedding any heat at all, for a while the cold water in the radiator will keep the engine cool.
If the heat from the engine exceeds the heat the radiator can shed, as soon as the radiator water hits the temperature of the engine, you will have overheating.
If you have a head gasket leak, you are injecting heat directly into the water, heat that ought to go out the tailpipe.
If some of the tubes in the core of the radiator are not flowing, the ability of the radiator to shed heat will be diminished.
I am thinking it is either a head gasket leak/cracked combustion chamber, or a radiator that does not flow water through all the tubes.
A lean fuel mixture will generate a lot more heat than one that is richer. The coloration of the spark plug insulators can be helpful in assessing the mixture.
