Pull the leads one at a time from the coil pack. if you pull a spark plug wire and the engine rpm doesn't change and there is a weak or no spark the coil pack is likely the problem.

I've a 1999 mercury stable 3.0 double over head cam it got hot and cut off when cooled off chanked it up and blowing white smoke it don't seemingly to have water in the oil does that mean I have a cracked...


If your engine has overheated then more than likely you have a blown head gasket.
1. have compression checked for each cylinder.
if a cylinder shows low compression 20 lbs less than the others then you have a gasket/head job needing repaired.
2. if there is water in the oil. your engine has a blown head gasket.

aluminum heads will need to be checked at a machine shop for warpped head...and all head bolts will need replaced.

I have a 1999 cadilliac , change radiator, cool system and therstat car still run hott


Headgasket blown or cracked head. You need to run a compression check on all cylinders. You can remove radiator cap and try to start. If the water is thrown out, you definitely have a headgasket/head problem.

How do i replace a blown headgasket


To replace a blown head gasket requires a lot of labor on this vehicle. Its a v6, meaning you have 2 head gaskets to replace instead of just 1. It requires removing air cleaner, disconnecting battery, removing most of the accessories that are belt driven, removing the intake manifold, egr valve and tubing, exhaust manifold on both sides of engine, timing belt removal, valve covers, and a few smaller items. After removing everything on top of the engine, you'll have access to the cylinder head bolts. Removing them will allow you to lift off the cylinder heads. Before replacing the gaskets, you must send them to a machine shop to have the gasket surface milled true flat again. They must also be inspected for cracks (which will sometimes happen with blown head gaskets) which would render them useless.
If this is a vehicle you really like, perhaps consider investing in a quality used motor. Its less labor intensive, less repeat repair, and you may come out saving a few bucks.

I have a 2001 mercury cougar with the 2.5L v6 engine and the number 2 cylinder is misfiring. ive replace the spark plugs and wires but it still misfires


Its time to do a injector balance and cylinder leakage test, to determine whether the injector or its circuitry is bad . The leakage test will tell you if the cylinder has a compression leak.

The engine misses on 3 and 4 and compression leaking into radiat


If you do in fact have compression (air) blowing in to the cooling systems this would show either a blown head gasket, warped head or cracked head. Please od not run the Rodeo until repaired as if coolant is getting in to the cylinder or oil (Your oil will look like chocolate shake) it can do severe damage. What motor please 3.0 V6?

Engine oil in antifreeze


you have either cracked the block cracked the heads or taken out the headgaskets. this can be an expensive fix to do it right you will need to rebuild or replace the engine.

Blown head gasket


Yes, driving around with a blown headgasket is BADDDD....

If you've never replaced a headgasket before then I would suggest that you not try it without proper supervision and help.
On a v8 when you replace one headgasket you replace the other as well. The gasket kit comes as a set of 2 headgaskets and all other gaskets and o-rings that will need to be replaced. You will need an array of tools to accomplish the mission - some hand tools and some specialty tools for dismantling the cylinder head.
I'm really not trying to scare you off but this is NO SMALL JOB. It will require patience and it will require tools and prior knowledge - so get the HAYNES RePAIR manual for the car and read up if you decide to go for it. I did the headgastets on my Acura Legend v6 - and what should have taken 30 hours start to finish took about 55.
Good Luck and Happy Motoring!!!!!!!
