I was surprised that no one came up with the obvious when answering the
gentlemans question about overheating after his radiator had been cleaned and
thermostat removed. The thermostat not only controls the temperature of the
engine but also serves as a restrictor for the water flow. It slows the water
down enough so the radiator and fan have time to cool the water before it
recirculates through the engine. If he puts his thermostst back into its
housing, with the clean radiator, his heating problems are probably solved,
provided the radiator is large enough to do the job.
