Problem:

While at idle trying to setup limiters in the basemap. temp on the laptop went well over 200*. stock temp needle was not even at the middle (thanks for the totally inaccurate guage honda *grrr*) anyway the upper radiator hose was Hot and hard ( full of coolant) the lower radiator hose was ice cold. So we figured the thermostat just wasnt opening ( although brand new) anyway I ran to pepboys bought another one and put it in there. same thing.

No way two new stats could be bad. Then it occoured to me.. if the upper radiator hose is hot. obviously the heat is coming from the engine. but how? the lower was soft and cold as ice. it cant be coming back thru the upper hose??

 

air bubble

 

We Bled the air out of the system, sorry forgot to mention that.

 

water pump working?

when u bleed the coolant system.

did you have the heat on high and let it idle for a few minutes?


btw, the honda gauges work, they are designed not to go up until it gets hot like 225-230 degrees...

 

Yes tried with the heater on, same ****.

 

does the fan come on?

Yes

 

do you have the hose that loop from the thermo housing to the intake manifold hooked up ?

 

incorrect thermostat for setup maybe one with softer spring. try maybe not even runnong the thermostat once, then check to see if the temps keep going up
