Thermostat

Postby Joshpath » Sat Jan 19, 2019 3:47 pm

What's the normal operating temperature for a New thermostat? It's not guinune. But operates at 180%
My scanner is reading 215%f-228%f
Is this normal before it breaks in?

Forgot to ask, what scanner are you using?
Had the new stat done today, truck seems to warm up faster.
Heaters toasty and warm too.

It's the Bluetooth scanner from Amazon. I believe the "bax elm 361". Something like that. I don't have it on hand at the moment.

Thermostats don't "break-in." They either open at the specified temperature or they don't, which is 180 degrees per Nissan. Typical pressurized automotive systems don't overheat until around the range of 248-257 degrees F., depending on the pressure rating of the cap. You don't mention under what conditions you are measuring 215-228 degrees F. At idle and at temperatures in the 60-80 degree F. range, I would expect to see coolant temperatures near the rating of the thermostat if everything is working properly...high 170's to low 190's. If you are seeing 215-228 under those conditions, I'd be a little concerned and would make sure my fan clutch and electric fan are both working properly and there is no restriction of airflow through the AC condenser and radiator cores, such as bent fins, debris stuck in the fins or leaves/papers stuck between the two cores. If I was monitoring temperatures while driving under various conditions, I wouldn't be alarmed at seeing temperatures in the 215-220 range, or slightly higher, depending on ambient temp, humidity, vehicle speed and workload. As far as aftermarket thermostats, I'm not a big fan and I usually stick with genuine Nissan. Many aftermarket thermostats tend to run a bit on the cooler side, however, rather than hotter. I'm not sure who is the OE manufacturer for Nissan in the US, but I wouldn't be surprised if it is Gates, who makes the coolant hoses and serpentine tensioners for out vehicles. In Japan, Fuji and, I believe, Sumitomo make the OE stats for Nissan.

As far my location is northeast USA and it winter out here
I believe it's the ECT sensor. My inferred thermometer has a minus 15 to18 % cooler.
I might be concern when spring comes
Thanks smj999smj and Graham

I'm going to swap it out for a new one That's the ECT sensor. And pray its the culprit.

Checked the rad today after the new thermostat fitting on tue and the level was low. The truck was parked on a slope, but previously when I check it’s done in the same place same slope outside our house. Have topped it up and going to keep an eye on it. Going to the garage tomorrow to ask for a small amount of antifreeze so to keep it to the same brand and strength if I need to top up again. Today I just used water.

10/4. I myself put water into the rad.
Distilled of course.
My buddie is bringing me some antifreeze that he doesn't need. Good perks I say. I got some ignition coils he can use too. Fair trade I do say!
