Can you run your vehicle without a thermostat?
Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.
Does my jeep need a thermostat?
A thermostat will stay closed until engine temperature reaches that pre-set level and then the thermostat will open to allow coolant to circulate. In answer to your first question, yes, your Jeep will run without a thermostat. However, it will run better and more efficiently with a good (Mopar) thermostat.
What should the thermostat be on a Jeep Wrangler?
Think about it… if the engine is at 210 degrees (or hotter, whatever), both a 180 and 195 degree thermostat will be fully open. There will be NO difference. On a cold day, yes an engine may run cooler with a 180 degree thermostat. Personally i changed mine out to a 180 the first week after i bought the jeep.
Why does my Jeep Wrangler have no heat?
If your Wrangler has no heat at all, it is entirely possible that the thermostat is stuck open. When this happens, coolant constantly cycles through the engine. On very cold days, this cooling capacity is not needed, and the engine never warms up.
What should the engine temp be on a Jeep Wrangler?
My engine currently reads about 210* (jeep says this is correct)and I have the factory 195* t-stat (I understand that the engine ususally operates about 10-15* above t-stat rating). I know that I would like the cooler temp on the engine, but will the performance be impacted (fuel/air mixture)? What will happen this winter? Will it run too rich?
When to know if your Jeep Wrangler head gasket is bad?
The first sign of a bad head gasket that most people are going to notice is a warning light or spiked temperature gauge. If you’ve noticed this, you need to get off of the road and get your Wrangler’s engine shut down as soon as possible, before any lasting damage can occur. A bad thermostat can cause the temp gauge or warning lights to come on.
