This should be the same engine as the Maxima. If that is the case, there is no reason to remove timing chain or get it out of time. The pump is driven by the timing chain, but is not "in time".

The pump is under its own cover. The chain tensioner is under its own cover. The pump is removed after the tension is released on the chain, the tensioner pinned in its retracted position to take tension off chain, and the crank is rotated about 20 degrees counter clockwise to slacken the chain at the pump sprocket without coming off the cam sprockets. Then, the pump is remove by removing its mounting bolts and then screwing in three long M8 bolts as jack bolts into 3 holes (carefully and evenly) to jack out pump. The pump is sealed from the engine case by two o-rings that must be replaced. I think the pump mount bolts are sealed with silicone when replaced. I would get a Haynes or other reliable manual.

If you truly have to reset or check timing, definitely get a book.

Getting to timing chain without tearing down engine 2000 dodge intrepid


I assume you're talking about the 2.7L V6. As you're probably aware (having had it apart before), the timing is properly set by aligning the colored links on the primary timing chain with the marks on the crank sprocket and cam sprockets. The only way I know of to see all these at the same time is to remove the timing cover, and you have to tear the engine apart to remove the timing cover.

2002 Intrepid: need to replace the water pump...


In the 2.7L V6, the water pump is driven by the timing chain. I'm pretty sure that in the 3.2/3.5L V6, it's driven by the timing belt. In both cases, it's a lot of work to get to, as you have to remove everything on the top (intake plenum, valve covers) and front (belts, pulleys, idlers, p/s pump, and timing cover) of the engine. Then, after removing and replacing the water pump and timing chain/belt, you have to make sure that the valve timing is exactly right, and reset the chain tensioner on the 2.7L.

A lot of work. Unless you're very comfortable with working on engines, leave it to a professional. You'll save yourself a headache (not to mention some busted knuckles). ;-)

Timing chain


A timing belt will no blow up the engine, however it will on occasion bend the valves, you will need to replace the belt and test for damage to the engine. Change the water pump and check all the pulleys while you are in there.
