Blocked airflow? Aftermarket/stock rad?

ja20_eg

block airflow??? and yea i have a aftermarket rad...

DPancoast

Full size? Half rad?

Did you burb and fill the system properly?

Are both of your hoses warm at operating temp? One or the other?

Aftermarket fan? Shroud?

DPancoast

Could mean your new thermostat isn't opening.

What kind is it? Oem? Parts store replacement?

ja20_eg

yea theres bubble coming from to top rad cap..when i fill the rad when i got done putting the new thermostat in...

ja20_eg

yeah, i think it is cause my buddy and them said for me to take it back and get a new one (autozone)

There's your problem. I've used two autozone t-stats in my EF before and they both did this to me. Go get you a Honda t-stat.

did you install it backwards?

the big end of the thermostat should face the engine and the small end should face the rad hose

if you installed it backwards, the wax pellet in the stat will read the colder coolant outside the engine and not the boiling coolant inside the engine and will never open up to let coolant flow

ja20_eg

i install it right...i look at the one that was on it b4 i took it out to make sure it right..

ja20_eg

you mean the actual one from honda.....
