Changed fan relay (fan works now) and water pump. Jeep still overheating - any ideas? Also, now it smells like oil is burning and smoke is coming from the dead center of the motor.

No check engine lights.

[elcorvino]

PS - I think the smoke could be from the break cleaner and crap we were spraying that got on the block.

Also, it stalled out at the light down the street... Is that unrelated? Or...?

Only thing we can think of next is changing the thermostat tomorrow.

Get some 1x1 square metal tubing and drill holes according to where your hood mounts on, this will raise the back end of your hood 1" thus letting heat out...it also defrosts your window in a jiffy if you live in an area with cold winters and it looks good

I want to fix it - not rig it.

Smoke is now gone - I assume it was some spray that got on the exhaust manifold.

Still over heating. The only 2 things I assume it could be is either the thermostat or my radiator is bad?

Venting / lowering the under hood temps does not lower the operating temp of the engine..

Describe what is over heating....... Does coolant boils out?, Temp gauge reads high?, Do you smell coolant? Is this after engine has run a while, or soon after starting? Does driving at faster speed make things better/worse than driving bumper to bumper speed? Have you checked your fluid levels including engine oil? Any loss of coolant between over heating events? What does your coolant look like (remove radiator cap only when engine is COLD!!), clear, or like milky mess, or mud? When engine is running and cap is off, can you see coolant circulating? Were you having these issues before the water pump install? Does your I6 have only the electric radiator fan or do you also have a mechanical fan? With engine running, heat on high/hot, are both heater hoses hot/same temp?

[elcorvino]

Speed plays no part (hwy or stop/go).

There are no smells

My temp gauge is reads that it is running hot after about 3 minutes of driving.

I just looked - all other fluid levels are good.

No loss between over heating (260 range) because I immediately shut it of.

All fluid looks good - its brand new - literally put it in 3 hours ago.

I was having these issues prior to water pump install - I changed the pump because it was leaking from the seal and I figured why not since I had it apart anyways.

No mechanical fan - electric fan only.

The thermostat and gasket are only $8. Is that my best bet? Is that what could be causing this to over heat so quickly?

I would say the thermostat or even the radiator cap? But your jeep overheats really quick so there might be something wrong. It should take like 10 to 15 mins to get up to normal temperature and then more to overheat not sure why your jeep is overheating so quickly.

Brand new cap - I've replaced everything but the radiator itself and the thermostat. I was thinking since it hears up so fast the thermostat is stuck closed.

Hmmm. A thermostat is closed until it reaches optimal temperature which is 195 then it opens. It should take longer than 3 mins for the coolant to reach 195. I'm not for sure but it could be a coolant sensor that tells the guage how hot the colant is.

I never really thought of a sensor. I wouldn't even know where to look. It may have take closer to 5 minutes but def not 10 - 15. The thermostat and gasket were only $8 so hopefully that will do it.

Yea and its easy to replace so hopefully that's the problem.

I'd put my money on the t-stat. Have you checked your cat converter? I've heard that if clogged they can cause overheating issues. Check your rad hoses for pressure when running. If the t stat is closed they wil be low/no pressure

[little_Jeep]

What other indications besides temp gauge are you seeing? When its hot, do you see coolant boiling in over flow jug? Radiator cap hot, or cold? Engine hot to touch? New thermostat won't hurt, but I'm not sure it is the issue.
