I've owned this 89 pathfinder for the last 2 years, I love it except the heater has always sucked. It's come to the point where it just has enough heat to keep the frost off the windshield and the temp just above freezing. I had a new rad and T-stat put in when I hit a deer last year. Does that mean my heater core is cooked?
Before I got the new rad the fins were disintegrating to the touch, can I expect the same thing to have happened to the little heater core rad?
