Question about Jeep Grand Cherokee
I replaced belt due to squealing and and also replaced thermastat. with the new belt still squealing . and also engine does not reach over 150 and heat does not get hot.
Your water pump may be sticking. With the belt off, check all the pulleys for freedom. Sometimes idler bearings fail. When was the system cleaned?

SOURCE: Engine Squeals
Squealing is commonly caused by a loose slipping belt, something a serpentine tensioner usually prevents.
To rule the belt out, apply some belt grip (available at auto parts stores) to the belt and pulleys. Then run the vehicle checking for a difference.
I have a feeling there won't be much of one. That means a bearing is making the noise.
Open the hood, have a helper rev the engine. Listen and try to locate which component (alternator, water pump, etc.) is doing the squealing.
Once located, it will eventually need to be replaced. The noise is the first sign of failure. If its the water pump, look for signs of leakage. On any of them, check for play in the pulley.
Remember to check the idler and tensioner pulleys.

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

Should be a tag on the core support somewhere that shows a diagram how to install your belt,usually its right on top where the radiator bolts to core support,open hood look down on top of support or its on the inside of hood open hood and look up see if theres a tag with a diagram of belt installation

Are you sure you are looking at the belt that is squealing? Usually the alternator belt squeals when first starting engine, PS belt will squeal when turning the steering wheel all the way right or left. It the tensioner is maxed out, either the belt is stretched, worn out, or way overtightened.
