Water on the passenger floor

I think that'll be my next step.I'd much rather do that than worry about a blown head gasket. Thanks for your help!

Just something else I noticed:

I let the jeep run yesterday for about 30 minutes and 15 of those minutes with the A/C on. Everything was fine while running, but as soon as I turned the car off the reservoir filled way past full and almost boiled. As it cooled the reservoir went back down.

Mine has done that in the past. Added "Fix Leak" by Barrs and hasn't done it in 2 years

I have a 1989 Jeep Cherokee XJ 2-door. This morning I came out to my jeep to go to work, and when I opened the door, the entire carpet on the drivers side was soaked with water. I looked on the passenger side, and the front passenger floor was under 1-2 inches of water! -- Just sitting there.

Where could all this water have come from? All of my doors and windows where closed securely. It was not there last night, and it did not rain last night either.

It did not rain last night at all.

It is not coolant, it is pure water.

That isn't possible. Where I live, It would be extremely tedious to get that much water into my closed, locked, and alarmed car overnight. There are no hose faucets, and my car is parked in the middle of a parking lot.

I have a 1999 Jeep Grand Cherokee Laredo 4.0 L 6- cyl engine. As of late, I have heard the sounds of water sloshing around coming from the front seat passenger side.

I am aware of the AC drainage problems that previous years of this truck have had, and the design "flaw" that made it impossible to get to the drain from the engine side, necessitating drilling a hole from the inside and trying to clear it out.

I am fairly certain (please correct me if not) that the 'WJ' 99-04 trucks were redesigned so that the drainage does not go directly into the car frame, and that it is visible on the passenger side of the engine side of the firewall. It certainly seems to match up with the housing on the inside.

I was thinking that maybe I was barking up the wrong tree but when I run the AC, nothing drains. Compressed air blown in this drain hole does not seem to help, and I am wary about poking a wire any further than I have (just the opening so far) for fear I could damage something.

So far, no water has made it into my interior, but once summer comes, it is probably only a matter of time before something gives.

Any suggestions?

Jack-

Thanks for the quick response.I am still worried because, like I said before, NO water drips from this drain when the A/C is on.

But in answer to your question -- actually, a couple of months before I took ownership of this Jeep (my brother in law owned it before me) almost the entire cooling system was replaced. The radiator, sensor, water pump, etc.

If this is indeed the case, how does one rid themselves of that air pocket? Is this what is known as 'burping' the system?

I asked about the burping as I have seen some references to that process on the net with older Jeeps, usually when people change their coolant. Involves pitching the vehicle forward among other things. Sometimes too much info is a bad thing. Lol

So, another thought here is that the use of aftermarket hoses and fittings during that cooling system overhaul are not doing a good enough job of keeping the flow at the correct speed?

This is the first vehicle I have owned that has shown this kind of a quirk. I guess I can deal with the annoying sloshing sound as long as it doesn't affect the performance of the vehicle or end up being a leak into my interior.

But.I guess we've tapped this subject out though, eh?

Thanks a lot for the feedback!
