Rings Need Time
Q. 1993 Nissan Quest GXE, 6 Cylinder, 137,000 miles, Automatic transmission, front wheel drive, power (steering, window, lock, window), front control heater, rear control heater, A/C. Car condition: The engine coolant temperature gauge is at normal or slightly below it. The coolant looked murky and radiator cap is rusty. Problem: The front control heater dial is turn to maximum but the air come out is cool. On the contrary, the rear heater producing decent heat when rear heater control dial turned to maximum. Are the thermostat, heater core plugged, heater control valve, front control dial or heater core plugged that are causing the problem and how do I diagnose these. Could you please help me. Work performed try to fix the problem: Yesterday, I flushed the radiator and replaced with new coolant.
A. No trick Steve, they will seat after a while. It will take longer for the rings to break in if you didn't hone the cylinder walls when you did the rebuild, but they will after time. If they still haven't seated by, about 8,000 to 10,000 miles, then you have a problem.
