Is it the Thermostat.?

Cheers

P.S. my first Aero. What a beast..!

 

it might be the thermostat. heres how to test your GM thermostat - remove it from the engine and put it in a boilong water. the spring should move, and if it works it should open widely, and it opens slightly or not at all i suggest you replaced it with a new one.

 

Don't bother checking the thermo...jsut replace it...cheap part. Make sure you buy a new gasket too.
