You should check it every morning for the next two weeks before you start your car. If it's full for those two weeks--you don't have to check it again unless you have more problems. It's also possible that you have the wrong type of thermostat installed. Did you buy it from the Honda dealership? If not, buy one from the Honda dealership and install it. You also need check the water pump. The easiest way to check it is to start the car and open the hood. Determine if you see any water coming out of the water pump. If you don't have any mechanical experience, take the car to a radiator shop and have them check these items and also run a pressure test. -- NEWSGROUP SUBSCRIBERS MOTTO We respect those subscribers that ask for advice or provide advice.

Maybe a bad water pump? That might be the problem,a worn or failed water pump. Do the fans switch on when the temp hits the proper setpoint? -- Jim Yanik jyanik at kua.net |

Re: 87 CRX cooling problems
I have some mechanical experience and have checked everything from hose to water level. The fans do kick on when the temp gets to a certai point. The only thing i havent checked is the heater core. I haven tried back flushing it yet. and if i do, whats the best way -- sdiesel61 ----------------------------------------------------------------------- sdiesel619's Profile: http://www.usenetcars.com/member.php?userid=207 View this thread: http://www.usenetcars.com/showthread.php?t=24698 |

Even it was, it shouldn't cause the car to overheat as a plugged heater core would just simulate closing the heater control valve. Eric |

I believe worn water pumps are a common Honda motor problem;it's recommended that the WP be changed when your timing belt is replaced (at ~60K miles.) -- Jim Yanik jyanik at kua.net |

Ive replaced the radiator, cap, thermostat and > checked fans. Everything seems ok. Any suggestions? I had an '87 Accord that I bought in '94 with 160,000 km and wrote it off in '02 with almost 380,000 km... drove it all over BC, through BC winters, one summer to San Francisco, and once with the whole family loaded up to Chicago during one of the hottest summers on record ('95) with the A/C running most of the way, and not once did the temp. gauge ever go above the 8 o'clock position. Except the one time the water pump busted an impellor blade and ended up with a hole in the casing. Amazing car. Replaced that one with another '87 Accord that lasted a couple years with a "noisy" water pump, and at one point the thermostat did go bad on that one. I replaced it with an aftermarket "fail-safe" thermostat - the idea with that is that if it failed, it would fail in an open position to prevent overheating... for over $12 (a "standard" stat was $3.50). After two whole days, it did fail... closed. And I was overheating again. Another "cheapie" 'stat, and all was good until the water pump finally gave out. Point of it all: even a brand-new thermostat can go bad for no good reason. Check that first. Easy way to test is just to remove the thing completely - it SHOULD take the car a lot longer to warm up, but that'll tell you pretty quick if the 'stat is your problem. --- avast!
