I have a '95 Chrysler New Yorker 140,000 miles. Recently changed the water pump and did not get the tension adjusted correctly. There was a lot of slack on the timing belt. When the engine tried to start I noticed that the crankshaft turned but the cams did not, this was due to the loose timing belt. Does anyone know what the position of the crankshaft and the cams have to be set to before adjusting the tension on the timing belt. I noticed there is a dot indicator on the cam gears and holes on the harmonic balancer.

What engine do you have?? It may be an interference engine and you may have bent valves.

Never never do a timing belt on a chrysler engine unless you are a mechanic that has done it a few times. It will end up very expensive as it looks like it might be. let me know.

Please note the * by the 3.5l engine. That means it is an intereference engine. If the engine has rotated once out of time you have bent or broken valves or the camshaft and or cylinder heads. The heads have to come off with out question. Sorry to be the bearer of bad news as it is an expensive repair over $1500. Good luck

I understand the possible damaged induced, however, do you have the set up for the cams in relation to the crankshaft when installing the timing belt?

It is a complicated procedure and requires all componenst to be set just right. I suggest you buy a Haynes book as it has some good illustrations of how things are supposed to be.

Suggested Repair

Treat the 3.5L as an interference engine: if it rotated with the timing belt loose, inspect for bent or broken valves and related head or cam damage, and plan on removing the cylinder heads. Timing-belt setup is complex and must be exact; use a Haynes or factory manual for the cam and crank alignment marks before tensioning the belt.

Conversation Summary

The owner of a 1995 Chrysler New Yorker with a 3.5L V6 DOHC replaced the water pump and left the timing belt too loose, so the crankshaft turned while the cams did not. They asked how to set the crank and cams before tensioning the belt. The expert identified the 3.5L as an interference engine and said one out-of-time rotation can bend or break valves or damage the cams or heads, requiring head removal and a costly repair. For the alignment procedure, the expert recommended a Haynes manual with illustrations rather than attempting the job without experience.
