Why is the thermostat on my Jeep Wrangler not working?
Hopefully you’ve caught your bad thermostat before this has happened. 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.
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.
Make sure not to mix coolants as red and green coolant don’t mix well and can end up becoming a jelly like substance. The last step is to start your Jeep up and let it idle. The temperature gauge should climb to 160*, 180*, or 195* depending on what thermostat you just installed.

Why does my Jeep Cherokee Run so hot?
Lol, but I’d be more likely to put in a 195 or slightly hotter stat in than leave it completely without one Engines with no stat will have trouble warming up, except on a hot day. Then they will run hot and not cool down from the coolant not spending enough time in the radiator to remove heat.
