[AT] vapor locking

[John Hall]

I am kind of thinking along the lines of the thermostat or water pump 
myself. We talked about flushing the system as well. All the "external" 
things such as clean radiator, engine, and belts are pretty much a daily 
maintenace thing so they are not the issue. Since it never vapor locked 
while running I would assume maybe the thermostat is not letting the water 
cycle when the engine is off (convection/thermosyphon). The heating and the 
vapor locking will both have to be adressed this summer.

If the engine is running hot. That will cause vapor lock.

It sounds like you have a running hot problem not a vapor lock problem.

The usual suspects are.

1. Thermostat
2. Water pump. "Impeller bad?"
3. Radiator clogged.


I assume it has water.
It is not 100%antifreeze. "Will over heat"
The radiator is not clogged internally.
The radiator is not clogged externally.
The fan belt is tight.

etc.
