jolut Posted October 3, 2018 Share Posted October 3, 2018 I have a problem with low engine temperature in my '88 terrano.A few weeks ago, I installed a new thermostat and it worked fine. Until recently. The needle hardly move now, especially when I turn the heat on. I changed the thermostat because of to hot engine. But can this be a faulty thermostat again?

onespiritbrain Posted October 3, 2018 Share Posted October 3, 2018 Certainly sounds like it is sticking open. You are probably going to have to take it apart again.You can’t test it by putting it in some boiling water and look to see if it opens and closes.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Slartibartfast Posted October 4, 2018 Share Posted October 4, 2018 I've heard of "fail safe" thermostats that lock themselves open if engine temp goes above a certain point (and tend to lock up for no good reason). Seems odd that a new thermostat would've failed already otherwise. I'd want to check the temp sensor and the temp gauge before taking it all apart again.

adamzan Posted October 4, 2018 Share Posted October 4, 2018 If you can get an OE Nissan one, go that route. The after-market ones always seem to be * * * *. Link to comment Share on other sites More sharing options...
jolut Posted October 6, 2018 Author Share Posted October 6, 2018 Cant find any problems except for the thermostat sticking open. I installed a new one, another brand, today. Will use the car tomorrow Link to comment Share on other sites More sharing options...
