heating problems
 

ok i just bought this 90 protege, a little SOHC 5 spd, and the temp one day wont raise and the next day it will run at normal running temp, could it just be a sticky thermostat? at least thats what i was thinking.

thats what it sounds like to me.

Just did mine and it is better now. Also, the rad fan thermoswitch on the thermostat housing was corroded and broke off. Replaced that too, car runs great again. Hth.

thanx, ill replace the t-stat and check the housing tommorrow
