Water pump bolt

[Hook#3287]

Been a while since I've had time to post here, I missed hanging out and reading up on all the great info & stories this site continues to dole out.

Last Feb I purchased a 98 two tone ct with 17k on her.  She's in great shape, had only two other owners, a service man (air force I believe) bought her new, then the second owner from him, then to me.

As I said, she's in great shape, mechanically and paint wise, but the problems I didn't see when I got her, were caused by the locality of the second owner who resides on Long Island, NY.

Seems he would ride her and put her away wet, covering her with a tarp ( which I don’t get, cause he had a garage) holding in all the salt air residue to get baked into all the nooks and crannies.

All the major parts are in excellent shape, but the things that a giving me headaches are the small nuts & bolts and small chrome parts.  I could only get three of the four front fender bolts out.  After snapping a easy-out in the 4th bolt, I had to drill out the head and could only get the fender off after I took the front end completely apart.  That’s ok, was gonna do it anyways.

I wasn’t planning on taking the water pump cover off till I looked at the bolts (rusty and corroded) and saw the cover was in need of some loving.  I’ve painted my other’s black and they still look good after a season, so I started removing the bolts.  Got three off without much problem, but the 4th, the bottom left, had welded itself to the pump.   Broke the bolt and broke another easy out (Brand New Snap-on).

In the picture, you can see the easy out, which is hardened steel and I can’t drill it.  It won’t budge with vise-grips and I’m afraid heat may warp the pump body.

New one is $150.00 and didn’t find any used on e-bay.

I’m wondering if I could drill it out from the back side (two bolts go through the pump and screw into the block and two just screw into the pump body, this is one of the latter) and use a nut and bolt?

Any ideas?  Any one got a water pump for sale?

If ya heat it up won't the aluminum expand more than the steel allowing the easy-out to turn ??

Here's one at Pinwall for $25 or so after shipping...

I quess so, I'm a wood worker not a metal guy.     I'm afraid of warping it, but it's no good the way it is, so i"ll try it tomorrow.  You've given me some guts.   Thanks

Use a half and half mixture of ATF and Acetone. Apply several times a day. It is the best penetrant I have ever used. (12 years in an automotive machine shop)  It looks like the bolt is sticking out of the pump a little if so take a small ball peen hammer and smack the end of the bolt 10-12 times like you were going to drive it all the way through. Use a small hammer and don't hit it hard enough to break the housing....not even close. You are just trying to help the penetrant and loosen the corrosion. This should mushroom the bolt a little and allow you to turn it with a good set of pliers. Try screwing it IN ever so slightly first, then work it back and forth till it turns freely. Be careful not to chew off the remaining bolt. If it doesn't move with gentle pressure soak it longer and start over. Hopefully the easy out hasn't expanded the bolt as to tighten it in the bore.

 In my opinion easy outs are an evil invention used to torture machinists. Drill the stud and use a heli-coil if it comes to that but an easy out is a dead end road. They can be chipped out with a good punch but it takes hours=not fun...very expensive.

Hope it helps,

you might try to drill from the other side.use a smaller drill just to get to the easyout,use a small punch to drive the easyout back out. after thats done if the hole is on center drill just under the tap drill size an try to tap the threads out .be careful to keep the tap perpendicular to the pump face.you may need to chip away some of the old screw to get the tap to start in the threads.it can be done,I've done it many times over 50 years as a machinist.

I hope it works out for you, especially that you manage to save the one you have.

I think (guessing) that Pinwall's (or other similar vendor's) auction stuff shows up in eBay
searches, but once some part has been through the auction wthout selling, it goes to his
eBay store. I searched that out of his store, there's lots of odds and ends there...

Another shot since you're already going to be heating the area. where the bolt piece is sticking out of the pump, once heated apply a crayon, of piece of candle and melt it into the joint where the pieces come together. Then try turning it out.

Thanks for the advice!

I ended up grinding down the back side of the pump case, where that bolt attached, on my bench grinding wheel, just enough to expose the end of the bolt.  Then drilled it out with several different sizes of drill bits.   By accident, I hit the hammer drill button on my drill, and that made the easy out pop out.   After that, I just cleaned out the hole with a drill the same size as the other two pass thru holes and got a nut and bolt the right size.  Looks like it will hold.

I'm just glad it wasn't one of the bolts that go into the block case.

Good news is, saved myself $150.00, might havta buy some chrome!

Thanks again everyone.
