Overheating on 2011 Jeep Grand Cherokee Laredo 3.6 cyl

[@RektNOOBTrader]

I had this exact issue, replaced the thermostat, radiator, cap, temperature sensor, hoses, water pump , this did not fix the overheating condition… I then replaced the brand new thermostat with a brand new OEM Genuine Mopar 203 degree thermostat and this instantly fixed the overheating condition and a bonus it fixed my Sport Mode… Only use Genuine OEM Mopar parts. I’m guessing the aftermarket Chinese parts are out of specs. Hope this helps.

[@hellycaraballo5249]

I went thru same issue, drive a 2011 also, it was an inner tube that was ripped , have them check all tubes that flow thru engine and radiotor.

[@landonjorgensen2486]

What do you mean inner tube could you explain further

[@NutssMungo]

Yeah can you elaborate a little more

[@hellycaraballo5249]

The inner tubes near the thermostat, you can see them underneath the thermostat

[@Junior185404]

Temperature sensor?

[@Lipripper1047]

You mean hose?

[@97camaro100]

Everyone keeps saying thermostat but make sure it’s a factory thermostat and not an aftermarket thermostat. I had that problem with my 2011 5.7 & I did a radiator flush, new heat core sensor, water pump, radiator fan, radiator cap, thermostat and gasket. After all that I still had an overheating problem so I went to my original mechanic and he let me know I had an aftermarket thermostat on there which doesn’t work for jeeps. After he replaced the thermostat I just got with a factory thermostat everything started working perfectly and I never had overheating issues again. Give it a shot and good luck.

[@alamuddeenross7447]

Thermostat housing??

[@RektNOOBTrader]

Yep, same issue with my 2011, the aftermarket thermostats are out of spec , replaced with OEM Mopar and it fixed my issue. I’ll only be using Mopar for now on.

[@DCParini]

SAME HERE! I have a 2013 3.6L and replaced the oil cooler, radiator, ac condenser, thermostat housing (twice) and so on. It still stays around 225-230 when driving and gets up to 240+ when I’m on the freeway.

[@jolantaharris3478]

Did you find out the problem

[@nikosmurph196]

How did you fix the issue

[@Junior185404]

Temperature sensor

[@elflacomayahua5910]

Did you figure out what problem was ?

[@mtsanchez27]

What was the issue?

[@kennethdurbin3385]

Have the same issues with mine but mine wasnt overheating at all. I heard my engine fan kick on while waiting to pick up my kid from achool so I stupidly swapped out thr thermostat. Now it overheats and fan wont kick on at all. Just replaced the coolant temp sensor and bled the system through the bleed screw on the water pump. Im guessing a blown head gasket since 99.9% of these trash cans on wheels are known for. Hope you decided to get rid of it.

[@Queroyw]

Easy fix for mine was I didn't let the engine idle for 15 minutes or more with the bleed screw open to allow all air to escape. Kept overheating UNTIL I properly bled all the air out of the system. Like new, now

[@centroamericasvr3199]

I like your idea, did you do it with the engine on or off?

Dang I let mind bleed and I have a ton of coolant that always comes out I can imagine 15 minutes of a content flow

Where's the bleeder screw? 5.7 hemi 2011 grand jeep Cherokee

[@tonyd0001]

@@kennethdurbin3385it’s on top of your thermostat

[@user-uw2pm9mm3x]

Mine also. I did thermostat and water pump and drives ok in town (210-220) but on highway or hills it over heats (220-240)

[@troyimamura1649]

Check your engine cooling fan and thermostat

[@ahedaolim7418]

I have the same problem and I tried all the solutions presented in the comments..and it did not work...we found the problem..the water pipes entering the heater were closed..the previous owner put a stopper inside the pipe in

[@Riverajr787]

I’m in the same boat exactly to the T all parts changed and replaced twice and still does the same when I start driving from start up it creeps to the middle then moves to about 240 then drops to 215 and stay like that the rest the time I see it’s only when I start on a cold engine so I would let it warm up now about 20 min before I take it out for the drive so far good

[@Chad504mob9]

Water pump, fan relay, temperature sensor or fan . Check head gasket as well

[@abrahemalkhuli2519]

I have a Jeep commander with the same issue, the Fuse box is probably a tiny bit burnt at the fan relay i bypassed the Fuse box and used a separate relay. Check if you have power going to the fan to confirm then check the status of the fuses and relays. If it's not an electric thing then check for head gasket leak

[@nouraalraeesi807]

Low fan speed issue

[@mikef4077]

Temperature sensors issues, the cooling fan kick in too early, prevent the thermostat from opening.

[@MSor1203]

Has anyone found out exact issues yet? Having same problem. 2011 with 195,000 miles.

[@Doreenhicks437]

It could be the fan relay or switch. The fan may not be coming on to cool the fluid

[@manuelmedina8880]

Having the same issue right now! Changed the thermostat wasn’t it. Then a leak from under the car. Took to the mechanic changing the water pump and then he gonna run thru the machine hopefully that fixes the issue

[@manaselpop]

What was the results bro ?

[@bb-zv6zx]

Have you checked your map sensor and changed your 02 sensor, down and up stream?

[@marscobras8281]

Engine damage occurs at 245-260 degrees in my experience. I have a corvette that seems to like 230 degrees. I hear they designed it that way for fuel mileage. Your guage on the left points on a safe zone. What kind of car is this?

[@manuelmedina8880]

Check water lump for leaks, this happen to me exactly it’s in shop now, hopefully it works

[@martinveo4445]

It’s probably the Coolant and Oil Assembly that needs to be fixed I had a similar issue about two years ago

[@JoseReyes-zo3hj]

My radiator fan wasn’t working and the problem was my coolant temp switch

[@PamelaaChu]

V6 engine is trash. When you buy a car like this make sure it’s a v8. Hemi engine would be a good option.

[@damianmontgomery3292]

Engine oil coolant system we had to change on our 2012 3.6. Also change the thermostat. It solved our issue.

[@iechiefcherokee3807]

There’s air I. The system park up hill and release pressure from your radiator if that doesn’t help bad radiator but most likely there air that was stuck in the heater core

[@douglasslee3781]

Replace the water pump is the front floor wet that could be a heater core

[@XABIH20294]

Change heating sensor,and check on any leak in the pipes around

[@chevychase9797]

Do you hear the fans coming on ?😊

[@richardbrooks8501]

Did you make sure your coolant lines haven't collapsed

[@landonjorgensen2486]

Same issue replaced pump and thermostat both easy repairs but problem continues diffinet improvements only hitting 230 max but still looking to get it around 220 or less thinking I will do the fan and relay next

[@landonjorgensen2486]

Did fan and thermostat still happening the jeep has a mild shudder at idle starting to think maybe a vacuum leak it mostly gets hotter when the shake is happening

[@Junior185404]

Coolant sensor?

[@Lipripper1047]

Radiator flush?

[@landonjorgensen2486]

Yeah did a flush and vacuume filled it to make sure no air in system I went back and replaced the thermastat again problem solved I was sold a faulty thermastat wouldn't open at proper temp upper hose was staying cool for to long

[@richardbrooks8501]

Did you put the right temperature thermostat in

[@chevychase9797]

If it is that the fans ain’t coming on your sensor is blown. U gotta replace

[@darrellpatton3549]

Did you check your water pump ?

[@Mike-jr1vw]

Mine was a heater coil hose, the crack in the 90° elbow

[@AdrianaGonzalez-bt9xp]

Have you replace the coolant sensor

[@chello978]

What about your heating core. Water pump.

[@jerrycalvario5693]

Have you already fixed your car

[@baker3162]

Coolant crossover pipe?

[@benitoberdecia7316]

You need to bleed the system. It’s a little screw, right where the water pump is at.

[@frederickbangura3339]

Is the engine housing cooler

[@jolantaharris3478]

I’m having the same problem did u figure it out

[@hisham982]

Need to program the fan by hptuner

[@elflacomayahua5910]

Did you get it fix ?

[@adenramirez870]

Thermostat! I got a 5.7 and had the same issues thermostat issues are usually easy and quick to replace especially on these jeeps. Even though I’ve got a different engine it still applies to you! Hope you got this fixed and runnin like new 😎

[@willjackson4739]

I got the same engine as you and I’m going three this right now

[@richardlamonica1360]

Hey bud. I have a 5.7 and it’s running around 225-230 with a new thermostat. What temp does yours run at. I feel like it may need a water pump

[@mossyminecraft7959]

Gotta get the right factory temperature thermostat i had to go through 3 of em to find the right one. These things can me quite touchy part wise.

[@mossyminecraft7959]

I also overheated on the road n had to ride through lt as it barely went with the gas all the way down, but that was my problem if that helps anyone

[@Farmor4x4]

Yo cambie mi termostato, limpie radiador y puse refigerante morado Marca MOPAR., y sigue así. Me falta la válvula de temperatura

[@Priv.alejandrn]

Lo podiste solucionar?

[@mtsanchez27]

Algún dato nuevo?

[@blackwarrior4699]

Just make sure the high speed fan is starting when reaches 100 degrees celcius !

[@ric1635]

How about your fan??

[@SmoothBrain23]

You either didn't bleed the cooling system by getting all the air out or the thermostat was installed backwards 😂😂😂

[@mrtakenols]

A bad water pump probably the reason this happened to me when I had my white Jeep

Thats the fan actuator easy fix

[@alamuddeenross7447]

[@richardbrooks8501]

Maybe your water pump is going bad and it's not leaking outside

[@xx-drew-x-and-xx8156]

Check water pump

[@XABIH20294]

Change heat sensor

[@Toolslinging]

if it only gets hot at idle then the issue lies in the radiator fan

[@alejandropatino1071]

Radiator fan

[@reachahsani]

I'll. Help you just turn off the car if it got overheated then call someone like any fixer and if you are going somewhere. Then get a taxi

[@mohamedayachi9034]

It’s your water pump

[@garagetoys87]

Most likely melted the fins on the water pump and cooled down in the heater core, that will restrict the coolent flow

[@xxramrodxx6149]

Mine did this and it was the tranny cooler

[@joselynmorales9859]

What's a tranny cooler?

Sell or junk it. These Grand Cherokees are garbage. Owned mine for a year now and dropped $8000 into it already. Now mine has the same issue but only reached 225 degrees so far.

[@kuzyordaddy927]

Buy a new radiator and coolant lines at this point tbh

[@L.A-]

Water pump and flat tire

Turn on the ac and then go check on the fan to see if it turns on. If not, that's your problem.
