anyone else had issue getting waterpump to seal?

I've having a heck of a time getting the inlet hose to the waterpumo to seal. I've had this issue with 2 different brands of water pumps and hoses. I recently upgraded the radiator and switched in a silicone hose I've had for awhile.

And today have a steady drip coming from the inlet of the water pump. Last time I had 2 hose clamps on it to keep it from leaking. I can't get this one to stop leaking either.

It's like the hose clamps don't want to sit square to the neck?

What clamps are you using? You could try a narrow band screw clamp or a constant tension clamp.

Ideal work drive style. I'll have to look for a narrow band clamp. I had tried the factory style last time and they didn't seal any better.

Re: anyone else had issue getting waterpump to seal?

For leaky coolant/heater hoses I always put a thin film of RTV silicone on both the hose and the hose neck. Dry both sides and clean with some solvent. Kinda like a differential, let the RTV skin over slightly, loosely install the hose, and then wait 1/2 hour or so and tighten the hose clamps.

Hmm had not thought of that, have some Hylomer Blue that is good for this type of thing as it doesn't set up like silicone does. Guess I will be draining the radiator again.

The narrow ones are common on European cars if you visit the junkyard.

Re: anyone else had issue getting waterpump to seal?

I had a slow drip in the same place after installing a new lower hose. Solved it by using a constant pressure clamp. That's a bad place for a leak because the hose tends to fit on an angle to the inlet, and not square.

I notice that with the hose clamps, they want to pull to the side as well.

Re: anyone else had issue getting waterpump to seal?

The inlet is a headache for sure. It's a big hose right behind the power steering support bracket with limited access to the clamp. When using pressure testers on new/dry setup, I find that they will always leak unless I dip my finger in antifreeze and coat all mating surfaces. Have not needed to use RTV or anything like that...

I use the worm style clamps on the bottom hose

Re: anyone else had issue getting waterpump to seal?

Well I got it all to seal up using Hylomer Blue and a constant pressure clamp from the local CAT dealer.

And then the water pump started to leak from the weep hole. And now get to tear it all back apart.

Re: anyone else had issue getting waterpump to seal?

I just crank the hell out of the regular worm gear style ones, never had an issue.

Did you make sure the hose clamp is entirely on the neck of the waterpump not sitting a little crosswise on the barbed section? I could see that leaving a low clamping pressure area in two places if it was on a little angled. It's not in a very fun spot to work, naturally.

Re: anyone else had issue getting waterpump to seal?

yeah the wider CAT clamp sealed fine, it's just leaking from another area now. That's the issue I usually have is the clamp ges crooked, guess that a bonus for the spring clamps ands they usually sit flush.

Re: anyone else had issue getting waterpump to seal?

Gates PowerGrip can be a really good fix for something like that. I have used these successfully on another car; no issues, no leaks.

The problem will be getting the heat gun in there to heat the grip clamp in your case.

Are you sure it wasn't just a leak from the weep hole all along?


I had that in 89 XJ and first changed the hose four days ago, but ended up changing the water pump yesterday!

Originallyit sure looked like a leaky inlet hose connection when inspecting from under the Jeep, but instead it turned out to be a failed water pump shaft seal.


The weep hole is kind of hidden behind the pulley.
