Quad or V6? If it's a Quad, and it's coming from behind the rear wheel ,inside passenger side, it's almost definitely the Waterpump or a VERY slim possibility that it may be your overflow tank. Chances are high it could be the Waterpump on a V6 too, but the puddle would form more center to front inside the passenger wheel on a V6.

It's the v6 but how could I diagnose that it is the water pump its not the limg is it?

What year is it? Depends if it's the 3100 SFI or the 3.1L MPFI motor. If it's the latter , it's almost surely NOT the LIMG's. If it's the former, it's possible, but usually LIMG leak will mix with coolant.

Its the 3100 sfi its a 94

Possible locations:

Side tanks of the radiator. Look for cracking.
Lower return hose, they can develop leaks. Same with the upper hose.
Water pump. Unit is mounted on the front upper corner passenger side. The belt goes around it with the ribs sticking out.
Heater hoses are common sources.
Check the press fitting behind the thermostat junction. Mine still leaks there at the moment. Been too lazy to replace the fitting. This will drip down on the backside of the engine.
Bypass line that runs along the front valve cover. Have heard of some that rust and develop leaks.

As for the LIMG. As SGR stated, it usually leaks internally, and MAY mix with your oil. Your oil will turn to the look of chocolate if this happens. If you have that, you need to stop driving the engine, as coolant contains crap that can damage the bearing surfaces if ran long enough mixed into the oil. In some cases you can have it leaking externally from the gasket areas where the lower intake mates with the heads. This is a common issue with 60 degree engines.

Good luck!

Every hose has been checked and there's no leaks and the radiators been replaced a month ago and there's no cracks and the upper hose was replaced.

I mean the limg has no erratic idle or anything like that and the oils fine.

As for the thermostat housing part how could I determine that? This leaks been a sob and its driving me crazy as I don't wanna get stranded

Well, being that your leak is coming from the pass side.... Doubt that's it. But if you follow the upper coolant hose back to the engine, it connects to a fitting slightly below the air intake (driver's side). Behind this fitting facing the firewall is a line that is connected to the heater core. The press fitting is right where the steel line goes into a big "bolt".

I'm betting its the water pump, from the location. But that's a guess.

I had a leak on my caravan a while back, I had a crack in the radiator, leak at the pump and both hoses were leaking. But I got it fixed, once I replaced everything.

[nikosuave8896]

Would the water pump have moisture around where the belt is? And if it was the gaskets leaking where would it leak is the spot I see the coolant leak be it? It's only a little coolant every cold start

That spit of coolant is where its coming from. It's kinda looks like its dripping in multiple starts and it was sitting.for about 3 hours before I had to drive it again

Sounds and looks like your "weep hole" on your water pump may be spitting. They ONLY start doing that when the pump is going bad. Considering you've checked everything else and all hoses are good, I'd say it's time for a new WP. They're only like $25 and easy as crap to replace.

[nikosuave8896]

Figured that lol pretty sure everything on this car was factory so in terms of changing the pump does the belt system have to come off? And Im guessing I'm gonna have to take the motor mount off? ( I really wanna do this job myself I'm spending way to much at the shop for this car for different things )

If it's on the pass side I'd say its the pump leaking but to be sure grab a compression tester and compress the cooling system. Do it hot and cold. That should tell you exactly where the leak is coming from.
