    I apologize for 'flubbing' that one! Shouldn't have posted a solution when I was tired! I forgot to state ->WHERE, the thermostat is on both engines!

    The thermostat housing is located on the front of the engine. Follow the ->Lower radiator hose, from the radiator, and you'll note that it connects to a manifold, on the front of the engine. This manifold is the thermostat housing. One of the heater hoses also connects to the thermostat housing. This hose will be 5/8 of an inch in diameter.

SOURCE: AC belt on 1999 Chrysler 300M

When you replace the AC belt you really should replace the serpentine belt as well, since you will have to take it off already. If you don't do it now it is inevitable that you will have to replace it in like 3 weeks anyway : )

You need to first remove the serpentine belt by loosening the nut in the center of the idler pulley. After that you will need to loosen the push bolt on the side of the idler pulley. The hub bolt is a 15mm size and the push bolt on the side of the tensioner is a 13mm I think. After you loosen it sufficiently, you will need to pull off the old belt.

Next you will need to loosen the tensioner pulley for the AC belt as well. It is the same process. The main issue is space. You will most likely need to raise your car to get at the right angles to loosen these pulleys.

Once you loosen the idler pulley in the same manner as you loosened the other, you can slip the AC belt onto the back of the crank pulley and route it as the diagram under your hood instructs you. Next tighten up the idler pully in the opposite way as you loosend it...tighten up the push bolt until the belt play is within factory specifications, then tighten the hub bolt in the center of the pulley. Do the same for the serpentine belt and you should be up and running in no time. I just performed these tasks on my 2000 300m and I wish someone would have told me this before I started my project. Hope this helps, Good Luck!

The thermostat don't work where is it located at to put it on the 99 chrysler 300m


Jacquelin! The thermostat n a 3.5 Chrysler 300M is on the block right next to, and toward the front of the engine by the oil filter. Yes, that sems a bit strange, but then I'm not a bit surprised about this engine any more. As the big radiator hose leaves the radiator finding its' way toward the block, it terminates at a traditional "goose neck" at the block behind the power steering pump- only accessible by removing the oil filter and using an extension and a u joint BUT FIRST: lower the anti freeze in the system by draining some fluid. But anyway- THAT'S where it is. Have fun, fix it up and GO!
