I have a 96 WRX STi.....I have a very cold bottom hose (from the Rad), the car's temp stays the same (about 3/8's)....I have changed the Thermostat (twice) and the housing and bottom hose is still cold.

Does anyone have any ideas what it could be? I'm lost.....

It is unbeleivable the amount of water I used......It actually evened out after I changed the rad cap from a 0.9 bar to an STi 1.3 bar cap...........but the bloody bottem is still COLD !!!!

Faulty gauge?

Is there enough heat coming out of the vents?

Sounds like an airlock to me.

As Alan says (Hi Alan), do the heaters come warm?

If all else fails, take your pipes off one by one and blow through them (including the heater matrix pipes under the intercooler and the metal piepwrk between the rubber hoses). Could be a piece of cr@p lodged in a pipe. I saw this recently in a car. It was sludge clogging the breather pipe from the top of the rad into the header tank, that was the same, bottom hose just wouldn't come warm. The gunk was lodged in the top of the header tank. Took the top off the header and cleaned it with a pipe cleaner and it was fine. That also makes it easeier to fill the header up!

When you top it up are you doing it with the heater switched to warm? If not you could be causing an airlock in the heater matrix.
