Timing belt - 1995 Chrysler Cirrus - RepairPal

all belts and pulley need to come off, belt and tensioner are located behind the metal plate on front of block. I would suggest checking the water pump and the two by pass o rings also.

my guess is your water pump is not working properly and the loud chirping sound is from the serpentine belt which also runs the water pump, alternator, ac and steering pump. first thing to check is coolant the cooling fan , thermostat , water pump in this order. chirping sound definitely come from the belt but the cause could come from any of the driven part but im zeroing in on the water pump because the car is running hot. old belt could also cause the chirping.

If it rattles,timing is too far advanced.Loosen the distributor bolt,Back timing to fastest idle,and advance it just a little to where the idle is changing slower.Not much tho.Lock the distributor bolt and drive it.If still rattles,do it again till it doesn't rattle.The rattle you speak of is called engine nock,because it's firing ahead of time too much.

The engine which is made by Mercedes is not belt driven, it has a timing chain, timing chains never need to be replaced unless they fail or the engine is being rebuilt.

Check the throttle plates and idle speed control motor make sure there both clean.

Also check manifold vacuum at idle the best you can hold an idle. I have run into timing belt being one tooth off and engine still ran fine. But the vacuum was low that's how I could tell the belt was a tooth off.

there is no belt, it a timing chain so no need to replace.

Yes this can be done in place,remove timing belt side engine mounting,lower rear engine mount and front mount and engine can be moved over to leave room to get the plate bolts out that is in front of the timing cover,its awkward but can be done.

The only engine that uses a timing belt in the caravan is the 2,4 and 3.0 engine which should be replaced at around 100k miles. The 3.3, 3.8. use timing chains with no service interval,
