Coolant leak - Hope someone has some insight

Hey everyone,

I got a coolant leak on my 93 YJ 2.5 the other day and it was a pretty fast leak.

After leaving it alone a few days most of the coolant was gone and when I checked under it looked like the leak was out of the lower radiator hose.

I removed the old one and didn't find much wear or any cracks. I replaced it anyway.

I recently replaced the upper radiator hose and the heater hose as well because those had cracked.

Anyway,

Besides those three hoses I don't know where else to look. Anyone have insight? It drips from the front of the oil pan right next to the belt and the top end doesn't appear to be damp at all.

Here are some pictures. Hopefully I explained it well enough. Maybe the water pump or something?

Water pump. Leaks tiny bits and it flows down.

A sticky to replace your water pump? Just look from below at the bottom of the pump and see if it's leaking from the weep hole. If it is, out it comes.

Mine was leaking in the same spot about a week ago i replaced the pump the thermostat upper and lower radiater hoses i also went ahead and replaced my tranny fluid coolant hose might as well replace the tranny hose while you got it tour down i have the 4.0 grand cherokee that hose is very unpleasant to get to other wise.this might save you some trouble go ahead and look the parts up from who ever you go threw just wright the part numbers down and match them up before you leave the store i failed to do that and the idiot gave me a water pump thermostat and lower n upper radiater hoses that went on the cherokee so that was the biggest waste of time with nothing but a tranny coolant line replaced it sucked

Not really sure. If i had a guess crawl under the front if the jeep look up past the front of the oil pan and you will see your water pump the weep hole is most likely going to be on the bottom of the water pump where the coolant is dripping,drizzling, draining what ever its doing...but like i said thats my guess if no one else replys about in abit ill get my repair manual and find out for sure

Yes that is the basics of a weephole. If the pumps bearing is shot fluid will be able to escape out of this little hole. Take your belt off and see if there is any play, side to side, up or down and in and out movement on the pumps pulley. If there is any at all, replace.

Box has instructions in it, drain, unbolt, clean, bolt, fill and test. Easy peasy.

You also have to pull the pulley off.
Most auto parts places rent the tool to take it off and put it back on.
Grab a Haynes or Chiltons why you are at the parts store.
It will tell you how to do it and what to torque the bolts to.

Coolant coming from the weep hole means your water pump bearing is shot. Once they go south , it starts wearing the seal and they drill a hole to let the coolant drip out and let you know before catastrophic damage. A waterpump that comes apart takes a lot of other stuff like the fan, the radiator beltts and hoses and if your looking at it when it does,you too. I was filling the rad on a fresh install of a new rebuilt one and if I hadnt bent down to pick up a dropped hose it woulda got me.

While you're right there, you may want to check the condition of your fan clutch and replace that if it's wobbly. 4 bolts and you're home free. As long as you're in the neighborhood .......
