1997 Challenger jet pump

[Danno97Challenger]

Sooo, I have my 1997 Challenger in at the dealer for winterizing. They called and said they went to change the jet pump oil, and it is full of water. They are recommending removal for inspection, etc. How big of a job is that? I'm not really wanting to pay them if I can do it myself. What do I need to consider? Any help is appreciated!! Thanks!

I would think they'd be able to inspect most of the concerned components when the drive is apart for the oil change. There's not much oil in there to begin with so there can't be much to inspect. One bearing I believe. Where do they suspect the water got in? Damaged O ring?

:agree: If the dealer has already changed the pump oil, I would do a pressure test, 10psi for 10 mins. If it fails the test then change the oil, use a new "O" ring, Loctite 518 anaerobic sealer, and check again.

You can get more details from the service manual. You can either make your own tester or buy one (also works for a pop off tester), if you want to know where to buy one PM me.

It's not hard to remove the pump, if you haven't done it before 30-45mins., but the leak was probably from the cone side, which means you don't need to remove the pump.

Not sure, they just left me a message so I will need to call them. I would guess there must be a bad o-ring to let the water in. I haven't done a thing with the pump, so I'm not that familiar with it.

If possible go there to see for yourself. Most likely as Lou and Biffitis suggested it's probably the o-ring ($5-$6) on the cone. Make sure they inspect the cone for cracks (not too likely), loose drain plug (maybe)...coat it (the plug)with teflon tape as 99spxxx suggested to me.
They will probably suggest or insist the they remove the pump to inspect it, if the o-ring is bad then that's probably the cause of the leak.

The more they do the more it will cost you.....at $75-$99 per hour of labor.

Thanks for the input, guys. I will go there and check it out. I will let you know how I make out!

I decided to have them put it all back together and replace the o-ring. I will inspect it myself next season. Thanks for the tips!
