mhuppertz Posted June 14, 2018 Share Posted June 14, 2018 My temps keep reporting overheat even though the car isn't overheating. Bought a new sensor, can't find the old one on the engine! Yes, I do need a service manual... Link to comment Share on other sites More sharing options...

mhuppertz Posted June 14, 2018 Author Share Posted June 14, 2018 (edited) Sorry, 1989 Reatta. I read the post referenced above but it didn't shed any light on the situation. Edited June 14, 2018 by mhuppertz (see edit history) Link to comment Share on other sites More sharing options...
2seater Posted June 14, 2018 Share Posted June 14, 2018 On the three LN3 manifolds I have, the coolant temperature sensor is below and slightly to the rear of the throttle body. It points slightly upwards and toward the rear. It is a two wire sensor. Link to comment Share on other sites More sharing options...
mhuppertz Posted June 15, 2018 Author Share Posted June 15, 2018 Thank you 2seater. Just changed it out and so far it seems better, but I won't know until I drive around in Albuquerque in the heat of the day. First impression is the new sensor is reading 15 degrees cooler.
