I barely have any heat in my '88 2.3n/a. I have replaced everything except the radiator. The car runs very cool all year round no matter how hot it gets even in the summer. Did these cars have a restrictor in the incoming heater hose???? Which side is the small coolant hose from the intake to the heater hose tee go to, the incoming or the outgoing side??? I'm pretty sure that I have all the hoses going the right direction but I would like a second opinion. There has to be something wrong because I had a '79 2.3 and I have a '84 SVO and both of them made more than enough heat even on really cold days.
