Check that the cooling fan is operating , if does check the coolant level and check the coolant for signs of oil , remove the oil filler cap ,look at the under side of the cap , if has a white/grey sludge that would indicate that theres coolant in the oil ,possable head gasket problem so would need further investigation at a repair shop.let me know how you get on

SOURCE: Lose belt on Jeep Liberty 2007 4x2 3.7L V6.

Most Jeeps use the power steering pump to adjust belt tension. there is a slide bracket at the bottom and a pivot bolt on top. adjustment is made by tightening a bolt at the end of the lower bracket. I have also seen this arrangement used on an idler pulley right below the pump but I may be thinking of some other vehicle.

This sounds very much like a faulty thermostat.

Can you see the cooling fans come on? When the engine gets to 212 degrees the fans should come on. To test the fans, with the engine running turn the A/C on high, the fans should come on .
The system also has a 212 switch that screws into the intake manifold. This is what turns on the fans with no A/C.
I hope this helps you.

Overheating engine in jeep liberty 2005


Obstructed radiator or plugged radiator, I didn't think that the Liberty had a fan clutch, I thought that it used an electric fan.

Picture of cooling fan

In the case of an electric fan there are relays and sensors involved plus the ECM (computer) is also in the mix to make that fan work.

I would suggest having the cooling fan diagnosed before doing anything else.

2005 Jeep Liberty 3.7L overheating


it's overheating, for sure,
is coolant levels dropping? cold checked at rad cap?
"pulled over and found a hose to cool the radiator and hose near the thermostat,"
i can not understand this statement"above"
if it overheat only parked, check fan for full ops.
if overheats moving too, wont stay cool moving fast
then:
bad rad cap
bad thermostat , they have 7 year life says STANT. (and why)
belts slipping (to water pump)
rad cores blocked (IR thermo gun it) ask
water pump impellers rust 1/2 gone?

all this assumes no coolant loss, if you have loss, tell where.,
where it leans
ground
passengers toes (foot well)
engine oil pan? milky oil
if A/T TRANS, check it for milky too.

2002 Jeep liberty overheating with a/c on then blows hot air


so the RAD is going to be good with leaks that it?
it has to hold pressure or it will get too hot,
14psi pressure,
I take my IR heat gun and check all rad tubes
top and bottom
and find, 3 are not 50 degree,drop end to end read same
those 3 are clogged, now you have 2 reasons to replace that bad rad.
something smokes, what?
it dont overheat parked, what is outdoor temp, 75f like here or 0F?
it must overheat idling, if it does moving.
how fan it not?
wont overheat A/C OFF you said.
so its marginal

ether rad tubes clogged
or fans dead,
one or both.

2003 3.7L Liberty Jeep overheated - no leaks in


thermostats are fairly reliable considering how cheap and simple they are.
They can and do sometimes fail (nothing is perfect). the cause is pretty much that they just stop working, usually because the internal movable part jams.
I believe a company called robertshaw makes what they claim is a "lifetime" thermostat...I doubt if it actually will last that long but may be a slightly better unit to use as a replacement.
I would use the opportunity to check the fan(s) to make sure they are working properly, that the radiator is not externally or internally obstructed and to replace your coolant.
if the overheat condition persists, check (or have checked) to make sure that there are no hydrocarbons in the radiator (indicates a cylinder head gasket leak) If your gasket has failed, it needs immediate service or it will cause serious secondary damage to the engine.

2002 Jeep Liberty 3.7L cooling problem (60,000 miles) : it would overheat if driving at low speeds (30mph and under) . Repair shop did pressure tests, results were good. Fan was checked out and was told it...


There is only so much to the cooling system. Although I
should be careful what I say cause my 02 liberty might over hear me and remind me just how temperamental their cooling system is.

I would replace the thermostat and if that didn't work you may want to remove the top plate holding the radiator down to check for any debris that may have collected on the radiator vanes.
I just replaced mine 3 days ago and the part cost around $20 so it's a pretty cheap item.

As long as your not losing coolant then that's about all you can do. If you are losing coolant regardless what the pressure test shows let me know and I'll help diagnose that problem.
Hope this helps.

1990 Subaru Liberty Overheats


Hi,

I had the same problem with my 1993 Liberty LX. Remove the thermostat (located inside bottom radiator hose engine connection - take the connection off and thermostat is inside). Reassemble (minus thermostat), reconnect bottom hose. Slowly (very, very slowly) refill the radiator and remove the bleed plug ( located beside the top hose connection to the radiator - a black square plug with a phillips head cross in the middle). When the radiator is full and clear water (no air bubbles) is coming out of the bleed point, replace the bleed plug and then the radiator cap.

Run the engine for five minutes (approx) or until normal engine temperature is reached. Allow the engine to cool down and recheck the water level - fill if necessary ensuring that the bleed plug is open and clear water is coming out of that point. Replace Bleed plug and then radiator cap. Run engine for five minutes (approx) and then test dive. If the engine overheats keep filling the radiator until there are no air bubbles coming from out of the bleed point.

This fixed my overheating problem. Good luck and safe motoring.
