RVdaytrader Posted December 6, 2014 Share Posted December 6, 2014 Hi, my 1989 sea breeze runs terrible for about 3 minutes till it warms up. Then it runs great. I am guessing it could be the engine coolant temperature sensor. Anyone agree with this or have other ideas what it might be?? Also, which sensor is it of the four sensors back by the firewall? And does anyone have a part number got the sensor? Different sites are giving me different part numbers! thanks in advance, RVdaytrader, (steve) Quote Link to comment Share on other sites More sharing options...
MontanaChinook Posted December 6, 2014 Share Posted December 6, 2014 Could be a few things. Does it use any coolant? If you're really unlucky it could be a head gasket leak, but there are definitely other things it could be. What leads you towards coolant temp sensor?

Uses no coolant, only about 5k on jasper engine so figure not head gasket....doesn't the coolant sensor tell the computer engine is cold at start-up and computer changes gas/air mix?...I really don't know and was hoping someone hear had ideas!

MontanaChinook Posted December 8, 2014 Share Posted December 8, 2014 Yes, you're probably right about the head gasket then. I was just throwing out the only idea I had. Hopefully some other people will jump in. I really don't know the V6 engines. My truck doesn't even have a coolant sensor. Quote Link to comment Share on other sites More sharing options...
Maineah Posted December 8, 2014 Share Posted December 8, 2014 The sensors are pretty linear so if there is something wrong it should just plain run bad. I don't know what you have for sensors but the coolant sensor will have a water proof connection with at least two wires and a locking tab. So if you have a hard start and poor cold running here is what you can do. Remove the connector and start it this will fool the ECM into thinking it is really cold and if that fixes the cold issue you can try a sensor. I sure there is a resistance to temperature chart on line somewhere you could check it with an ohmmeter also. Quote Link to comment Share on other sites More sharing options...
