My Jeep 4.0 is Overheating😭

[chestrockwell]

Inline 6 is known to get hotter than usual so I not only replaced my entire cooling system on my 2000 WJ but I also cut vents in the hood so it can breathe, that's why you see lots of jeeps with vents it's not just to look good 😆. I did all that for less than 300 bucks

As a former mechanic... "good luck buddy!"!

Take the thermostat out, leave it out and put the housing back on. That will tell ya if that was the problem. My old cherokee went 2 years without one.
Also, you can boil the thermostat in a pot of water, stay near the pot and listen for it to pop. If it pops its good.

That's not overheating it's normal temperature

The thermostat 😂 at least you're positive about guessing the issue. Helpful video though

I took mine out it stop over heating but it could also be the fan since it’s a two speed the first might come on but not second it needs replacing trust

[GREATBASINADVENTURE]

It might be the fan i had to do a bypass mod for the wiring

If you want to know if your head gasket is blown, just change the oil.

Most times, you'll find coolant.
Otherwise, check your exhaust for odd smelling smoke.

If that fails, you have a blockage, your water pump is probably bad, or you have a cracked block.
Fun times.

Check for coolent flow, fan clutch or fan is pulling air

Try burping the cooling system.
Worked on mine .
Get the funnel system

If it runs with all those accessories that you put on it, bigger wheels and tires etc. to be the 6L 4.0 engine ??

Filling this is the key. Use a lift pump. Mine suffered the same thing, and would overheat after replacing the thermostat and water pump. Unlike some GM units that had a bleeder valve in the system, MaMopar didn’t think that far ahead. A lift pump is the only way to fill the cooling system properly, as it pulls a vacuum on the system. Which in and of itself is useful as you can check if it’ll hold vacuum over 10-15 minutes. If it does, no leaks. If it fails, ya got a leak somewhere.

you were at a salvage said you could get parts need a drivers seat 01 jeep grand cherokee larado

[hanzgruber]

With any old jeep you need to replace the entire cooling system every few years because everything Mopar builds is junk
