You do have to either run the engine to operating temperatures/coolant operating pressures or apply pressure to the coolant system for it to leak in most cases. Just letting the car sit without running the engine usually will not show any coolant leaks at all.

So I found the coolant leak. I haven't driven the car in a few weeks due to my brake issue. I finally got around to buying a new jack(since the other one was stolen). I noticed it has leaked a little bit on the floor. Soaked one piece of cardboard. Here is a picture of where its leaking from: It appears to be the hose at the bottom of the water pump. Is there anyway to tighten this clamp without take the entire front end apart?

That said, because that (worm) clamp is situated to where you can't access it easily, I would (and have done) suggest cutting it or grinding it off (w/ a Dremel tool, perhaps) and reinstalling a new one where you can access the tightening screw easily. But, as with ANY such non-spring clamps, the (hose) material will migrate or collapse under pressure so that if not re-tightened from time to time, they WILL often leak eventually.

You don't have to be able to get a screwdriver in there, but rather a 1/4 dr flex head swivel and some extensions. Maybe the nut size is 7 or 8mm for that type of hose clamp. Looks like you have to go down thru the top some way.

It sounds like this is not the correct type of clamp this came with from the factory. So what is the best way to change out this clamp? Do I need to tear everything apart, should I just focus on getting this one tightened?

On aluminum or brass the screw clamp will work fine. Jerry's Gaskets sells the spring clamps but you would have to remove the hose end from the pump to replace it and that hose is a hard one.

Long as we're on the subject of those &%$)#! spring clamps, does anyone have or know of a tool for removing/installing those things that will work from any angle? (I suspect the only reason worm clamps even exist is because those spring clamps are sucha bitch to install/remove w/o some kind of special tool.
![]() Suggestions??? WVZR-1? Anybody?? (Not meaning to steal the thread! ![]()
