okay so im not that tech savy when it comes to this car so im going to try and be as descriptive as possible. i have a coolant leak in an elbow behind all the belts near the top of the engine, to make matters worse my heat has decided to randomly stop working, for a quick fix i used jb wet weld to plug the leak and it seems to be working fine but now it seems the problem is that even though i the coolant system is flowing its not sensing when its time to kick in i.e. the fans dont kick in almost ever. when i turn on my heat all i get is really really cold air even when its warm outside. im sorry for being so lack of any real technical knowledge but i just dont want to walk into a shop and havesome guy say its this and that pay xxxx and it end not being fixed because that wasnt even the problem. thank you guys for the help! sorry if im a lil vague

Oh, no worries man!
The coolant elbow can be found at Autozone in the "Help" section. It'* a 2 pack. One fits, the other doesn't. Cost'* about $5. Here'* the kicker. 1 of 2 things need to come off to change it out. Either your UIM and LIM have to come off, or the pulley with the coolant hoses have to come off to replace the elbow. Now depending on what year your car is, it would be recommended that you remove the the Upper and Lower Intake manifold to do this. This will allow you to replace those constantly failing gaskets.

Now, about your heat. Do you have manual heat or AUTO electronic system?

After plugging the leak, did you check the coolant level? With the engine cold, remove the cap from the radiator. I'm willing to bet your low. Top it off and it should be OK.

Looks like Dan has remembered to start with the simple stuff

Sure, forget to check one unlabeled fuse and I never live it down.

Those elbows failed on mine and I got them at an auto parts store and we just took the coil packs and water pump off to change them and I agree top off your fluid
