1996 F150 Water pump replacement #4511519

While changing the oil in my 1996 Ford F150 I noticed coolant dripping off the frame. This is a 302 V8 with 133,000 miles. I bought the truck used and I believe the water pump was changed in 2014 at 110,000 miles. (According to the Carfax I received)

The leak is NOT coming from the weep hole. It appears to be from the gasket itself. Researching this particular job indicates a problem with the bolts seizing into the timing chain cover and breaking when removal is attempted. The leak may be coming from the timing chain cover.

I just took another look, and I am 90% sure the timing chain cover is the source of the leak. This appears to be a Big Job.

Does anyone have any pointers?

Don't break the bolts. Some are obsolete and the ones still available cost more than the truck is worth. Dorman does make some of them.

You will need a pulley puller to get the balancer off. The timing cover is likely corroded and will need to be replaced.

Consult the factory service manual for the procedures. Don't try to go in blind.

I did it on my 1996 Explorer 5.0 engine, the harmonic balancer needed to come off.

Ok, I've been reading up on this and I am getting ready to tackle the job. I just placed an order with RockAuto:




I am hoping to be able to reuse the timing cover.
I still need to line up a harmonic balance puller.

You may want to replace the balancer while its off,rubber around the steel can slip, should be 50 ounce imbalance.May also do a timing chain while in there.

I don't know why anyone would want to work on a car without the service information; makes no sense to me.

I do indeed have the factory manual on CD. I was just asking for pointers as to what to watch for or common problems not covered in the manual. Such as broken water pump bolts.
I am considering changing the timing chain set, but I plan on waiting until I have it apart to inspect the old chain.

The harmonic balancer is over $200 at RockAuto. It's not getting replaced if I can keep from damaging the original one.

Use an air wrench or small impact to remove the bolts. Typically the quick shock will break the corrosion free without snapping the heads off... ask me how I know frown

The $200 is more than 50% of the way for a high-quality balancer; the factory rubber ringed ones are junk when they were new. Make sure you get a double roller timing set and it should be the last time you need to open the front of the engine.

I wish you would've said that in the first place. I get anxiety attacks whenever someone starts asking for information without having a service manual.
