Why the expletive is this hapening, if i let my car idle in my shop the thermostat opens fine.

but if i drive it and put it under load the thermostat will not open.

tested thermostat.

anyone.

 

How do you know that the thermostat is not opening "under load"? Do you have a little camera in there?

simple. my gauge goes way up. i get out of my car and grab my bottom hose and its cold.

can i get another witty response? cause im not in the mood

 

Ive had Issues with the Cheap thermostats from Autozone, Advanced, Pep boys.. all those part stores ive had issues with it. i got a OEM honda one and it worked like a charm. Friend has a Mugen one and it is just as good. just more expensive

 

i tested it out of the car also, worked great..

i dont think its an issue with the thermostat.

 

Last time you had a coolant flush? how do the bearings sound in the waterpump? cooling system is very short so it shouldnt hard to diagnose.

 

just a thought...

i had my thermostat installed backwords, and the seal wasn't on fully... gave me a funky temp reading until i fixed it

 

lol ive tried to install one backwards and it wouldnt go at all. so i dont know how you installed yours backwards

 

its installed correctly.

with the pin up also.

nothing is blocked, cause when i idle it to warm it opens and the car is able to drive.

 

This sounds like your waterpump blades are shot...No circulation will cause that lower hose to be cold just like your describing...
How old is the waterpump?

it seems to be circulating fine, my heater works great and if i pull a hose at idle its pumping good.

also i sed that if i let it idle, thermo opens and then i can drive it anywhere i want. but if i take it on the road cold. it will not open.

i am gonna put in another thermostat today and see what happens.

 

imma pull the water pump out as a last resort.

the OEM thermostat worked a bit better but it did the same thing irractically.

 

Check the waterpump man. Im 99.9% sure its your problem.

 

i ended up running straight water in my system for 6 months, heres what hapened:

the fins on the water pump got little dimples of rust on them, and i believe this was causing cavitation of the water pump at higher RPM/temperature.

i replaced it all and finally i replaced my water pump and it solved the problem.

moral of the story, always run a little bit of antifreeze in the rad to keep that **** from rusting.


THE END!
