2000-01 Cherokee 4.0 Temp sensor?? Right rear HEAD
 

Hello all,


I have a 99 Cherokee 4.0 that I just putt an 01 cherokee 4.0 motor in... It looks to me that on the top of the head near the firewall driver side, is that where the coolant sensor is??? There is a hole there and coolant is coming from it... I just want to clarify that the hole is for a sensor or something else.... It is on the top of the head not on the side, right near the last head bolt

Thanks all,

Ant...

R u sure it's a '01 head????? I's my understanding that '96 down heads had the sending unit hole driver's side rear. '97 up no hole. U'll need to install a pipe plug in the hole. '97 up heads have the temp sensor in the t-stat cover at the front of the head.

Hmmm, No Im not sure..
2000-2001 jeep Cherokee classic 4.0 remanufactured engine was what I purchased ( Long Block ).. The only diffirnce it has the holes for the coil packs.. My 99 has a distributor..


I guess I will Just plug it, Just wanted to know what it was there for..

Thaks,

It's for the sending unit on an OBDI motor. Look for the casting number on the drivers side near the #3 & #4 cylinders.

If you haven't figured it out by tomorrow, I'll take a look at mine, a 2000. I have the head off, so it's easy to see. I do know that on the 2000, the temo sensor is in the t-stat housing, on the front. It is leaking from the top of the head, and not the back? I ask because there is a freeze plug on the back of the head.....RR

Yes, The top not the back is correct..

I did put a temp sensor in there to plug it up and all is good now ( Didnt Have a plug ), If you can take a picture and post it so I can see it from the top facing down, Just want to see if your head has the same hole.. I am gonna see if I can see the casting #s on my head tomorrow ( its dark Now), Should of looked at them b-4 I put the damn thing in.. HehE!!!
