Snap-On Water Pump R&R tool

9 posts in this topic

I had difficulty getting the water pump out of my friends 98 Eldorado with my Lisle water pump tool. With a mirror I noticed that someone had tried to get it out before as the pump had deep scoring where the tool engages it. So instead of removing and replacing the pump they loaded the cooling system up with tablets but the cooling system continued to lose coolant through the water pump seal. This is the first time I have seen a NS water pump leak through the seal usually I see them leak at the pump body o-ring. This looks like a cheap water pump however, I replaced it with an AC Delco pump.

Although Lisle makes good tools, their water pump tool is a flexible tool and I have always had difficulty with it bending and getting out of shape. It always seemed to be a miracle when I r&r'd a pump successfully.

I gave up and told my friend I needed to buy a better tool.

I lucked out and found a Snap On S6192A Water Pump tool on Ebay, from a mechanic who currently works on Corvettes, he previously owned a Seville. The same tool is on Snapon.com for $150 and I found it on Ebay for $25!

Well the tool arrived quickly and it made R&Ring the water pump child's play, the stabilizer bracket keeps the tool in place so the tool does not slip. It is a ridged carbon steel tool with very sharp tangs on it. It does not bend and as a result keeps its shape and gives a more positive engagement and turning power. Used an 18" breaker bar to remove it and a torque wrench (set at 72 lb.ft.) to install it. With careful listening, he now needs a new tensioner, the tensioner pulley is very noisy.

Terrific find.

That was a steal at $25.00! That's what the POS Lisle tool costs. What usually works to get the pump out when the Lisle tool flexes is an impact wrench. The hammering action from the impact vibrates it loose.

I know what a steal! There are more on Ebay but I don't see any as inexpensive and there are not a lot that have the stabilizer bracket. I have been exchanging messages with the seller he is a very nice guy, I invited him to caddyinfo.com if he ever needs Cadillac help. Thanks, Kevin

Sometimes those waterpumps get seized in the housing. I use a air hammer with a long sharp chisle to cut the actual impeller off and then I work the pump body off the housing. Works like a charm!

Wow, I hope never to have to do that. The last pump I tried to get out I thought I would be cute and try to tap on the tabs with a long punch, nope, they bend like butter.

Some people doing the job for the first time try to turn the water pump the wrong way to remove it.

Very true, counter clockwise to take off

Actually, I'm pretty sure it is clockwise to remove and counter-clockwise to install. Sometimes people attempt to turn it counterclockwise to remove it and wind up bending the tabs, then they cannot get it out of the water pump housing.

Yes your are correct, pushing toward engine is in fact clockwise which is counter intuitive to lefty-loosy, righty-tighty and that is what Jim was referring to...good catch on my counter-clockwise mistake
