Just put a car (260K miles) on the road after it had been sitting 2+ years (in a dry & heated garage).
Had to replace various bushings, belts, voltage regulator etc - the usual after a car's been sitting.
The heat is lukewarm at best. I replaced the thermostat; the coolant is clean; heater valve seems to move freely; it warms up quickly & temp gauge needle stays in the middle. On a cold day - say high 20s F - the defroster air barely unfogs the windshield and the air through the vests just never gets hot.
I've never had this problem w/ a 240. I'm guessing a clogged heater core or a stick/ bad/ clogged heater valve. Someone used black silicone around the thermostat: It looks like he/ she coated both sides with ~ 1/4 tube of silicone (to compensate for a brittle rubber gasket?) and I wouldn't be amazed if pieces of that found their way into the heater core.
Has anyone had this problem and fixed it? I don't want to run flush through it as I've seen that create leaks. I could try to backflush it but that's not a fun job this time of year.
