I need a timing chain for my 2002 murcury mountineer do my engine have to come out

If you break a timing chain or belt it's high possibly you could of detonated the engine, which includes a great deal of damage including bend broken valves which would definitely prevent the vehicle from starting being it can not get the proper combustion

If the radiator is full of coolant, and the heater hoses are both hot, you could have a problem with a blend door under the dash.

This engine uses a timing chain not a timing belt, a timing chain never needs to be replaced unless it fails or the engine is being rebuilt

Here is a photo for you. Hope this helps

When repairing you cars timing chain , remember to research your cars firing order before you start . You can pick up a mechanical car model book at your local parts dealer . More? ChaCha.

how long can you ride on a bad timing chain before the engine goes out

Yes ,there is a lengthy proceedure to time both chains. I have the shop manual, and no way to scan it and send it to you. It looks worse than timing the V8,you just don't need a couple hundred worth of tools,as you do with most Ford OHC Engines

You can search the internet,but I wouldn't count on free.

You,mention subscription. You may be able to get a repair shop,that has those tech lines and info on CD's ,and over the internet,to print you, what you need ,for a few dollars.

I would get the procedure first, then study the engine and take pictures, as you disassemble,only as you ID what is on the assy sheets.

It looks like your only expense ,will be a sharpe,to mark chain links and a paper clip, to hold off the chain tensioners.

Not sure if it is a zero clearence motor but if is....you will need another motor......sorry !!!!

Hi there;

Here is a picture of the timing marks for the 2002 2.7L intrepid engine.


Hope this helps
