Hello !
Can some confirm that the spring end of the thermostat goes in the block. I remember always putting the spring on the hot side of the system but I've had one failed, I installed an new one, engine's heat wasn't working properly, I thought, ok bad thermostat, I installed another one if you go over 50 km heat drops right off. I have a number 3 on my desk and wondering if I'm missing something ?
I have 1996 Cavalier 2.2.
Thanks & Take Care Roy
