Hello, I need a drive belt diagram for a 1988 Cadillavc deville (4.5 l) The diagram in the engine compartment is missing. Thanks

There should be a diagram of the belt path on inside of the engine compartment. It will be on the under side of the hood or right by the latch.

I need a serpentine belt diagram for a 1990 cadillac fwd. 4.5 ltre. engine fleetwood sixty special

Hi, when a belt comes off, it's usually because of a bad bearing in one of the accessories or idler pulleys, or maybe your tensioner spring is broken. Remove the belt and check all pulleys for spin and play. It is also possible you lost an idler pulley and the new belt routing is not turning the water pump in the right direction. Check the routing and look for a missing idler pulley. Let me know if you are missing the routing diagram.

There should be a diagram somewhere in the engine compartment showing you how it goes unless it has been removed at some point.

Good Luck

Hello, That belt drives the waterpump, if the belt came off then you have a problem. Either the pulley on the tensioner is locked up or the waterpump is locked up. It may have destroyed the pulley on the camshaft that drives the waterpump. Remove the black metal guard that covers the large pulley. Hope this helps to get you started.

It is the engine front cover( from diagram in the 1988 service manual

Here's a link to the diagram you need...

Good luck and please rate this solution. Thanks.

1985 has the 4.1 engine not Northstar and is not serpentine.

Hope this helps.
