I posted about this a while ago but don't drive much. I've an 87 CRX DX that refuses to cool itself properly. I've replaced the head gasket, thermostat, thermoswitch, temp sending unit, water pump, radiator, hoses - in short the entire cooling system exept the guage in the dash. I've shorted the fan switch so the fan is always on. I've also richened the mix several times (now the adjusting screw will not turn farther). I've a little 400W amp in it, but that's it. After driving it for 20-30 min the temp guage reads about 3/4-7/8, even on the freeway. Odd thing is, sometimes it seems to cool itself just fine. That's the part that baffles me. (But usually it gets too hot.) Any suggestions?
