Hey guys

my ef over heating when the car warms up.

i tryed removing thermostat and driving see it the thermostat was jamming closed but still over heated.

Checked for air in cooling system

checked thermo fan operation

checked coolant lvl and condition

if i drive over 1500rpm she head up quick when she warms up driving to work and to cool down again i have to put the clutch in and roll down the hill and she cools down when ideling and moving with traffic.

i did a compression test and got ever 200psi within 5psi above and below(dry)

did a quick coolant leak test and pressure did drop but i don't know if it was the tester leaking it self or the engine it took about 5mins to loose 10 psi of pressure when i pumped up 120psi and let engine sit with no plugs.

have it a crank over without engine fuse and no water cam out of the plug holes.


Anyone got any idea's???

im starting to think it a head gasket or cracked head.

radiator(copper) only 7months old if that

thx jason

when the engine is warmed up, and the thermostat opens, squeeze the top radiator hose together and see if you can feel the pressure of the water pump. seems as if it might be worn out to me.
