Arg!! Coolant Leak!

My 08, JK w/6spd manual is leaking engine coolant right at the right front of the oil pan, it seems to be leaking around one of the bolts, I did a search on this and some suggested that the WP is leaking but I do not have any weeping or any coolant on the front of the engine at all. It is isolated to this one area. I bought this JK about 8 weeks ago and just noticed the leak on my garage floor 3 or 4 days ago. I am somewhat puzzled as to why there would be antifreeze around that area?? I checked the bolts and tightened each one about a quarter of a turn and that seemed to slow it down a bit. So any 3.8 gurus out there that can shed some light on this. I would like to repair this myself but (37318 miles..no warranty) how could there be coolant weeping around that bolt...there are no signs of any coolant getting in the oil pan.

I think Jimbo is thinking the same thing I am. Verify that it's coolant and not trans fluid. Both are red.

Yea, GH cause the two auto cooler lines run right there with the rubber vibration couplings, at that point and they do leak, now and then !!

Coolant!!

yea it is coolant, if you touch it on your tougue it has that sweet taste...definately not trans fluid...the only place I see it is the very right front of the oil pan, if fact if you wipe it off with a rag you can se it weep out between the area between two bolts. I am puzzled as to how I can have it there but no evidence of coolant in the oil pan

6-speed manual, I don't believe it has tranny coolant lines. This must be weeping fron somewhere else... I had a leak at my coolant storage tank but it did not run down to my engine, just the drive way.

Look in front of the engine with some light !

I took this pic when I first got the JKU, in case I'd have to change the serpentine belt-



Check the thermostat housing for leaks, cause it can leak in one spot then follow the pan/block surface and it may look like it's coming out of a point-when it actually isn't !!

If you can't find any traces of antifreeze on your eng. dipstick and the engine runs OK/cool, the leak is probably external

Remember, gravity makes all leaks gather at THE LOWEST POINTS and those aren't necessarily the leak !

Yea, I don't know why I even mentioned the coolant lines--there ain't none !

I'll echo what Jimbo said to find the leak.

Even though this is a manual, the TC has trans fluid. Leaks are weird and I wouldn't be surprised if fluid found it's way near that oil pan :P but since we know it's coolant, well...we know lol

Your heater core could be leaking and running down to that area. I think!!

Ah ha!

I think I found the leak, there is a little stream of wetness coming from the very bottom of the WP housing and running into a little area and down the timing cover. I can't see any weep around the water pump shaft but I'm just going to replace the water pump hopefully that will take care of it.
Thanks for all the input...what a rich resource this forum is! You guys rock.

You can try taking it in. The dealer may cover it under warranty even if its expired. Especially if the wrangler isn't modified.

This could be the Casting Porosity ( little pin holes in the Aluminum casting for the front cover or Water Pump..) that Mopar mentions.....If so it's a recall thing I'm sure...
Check that 08 for Oil Consumption too, check the dip stick regularly !!
