Mystery Coolant Leak

[7camaro7]

I know the coolant system doesn't need to be serviced until 100,000 miles. I checked it anyway in the reservoir on the pass side and it was BONE DRY! The car runs great! I took it to valvaline (since they happened to do my last oil change) and they filled it up for me for free. Well a few days later I pull my car into the shop at school and there are a few drips on the floor. It drips from the oil pan and we cannot see exactly where it is coming from. It drips off of the passenger side of the front of the oil pan. Anybody else dealt with this?

check the weep hole in the bottom of the water pump.

that's what I was guessing

What's a weep hole?

[sunsetorangess]

Little hole under the base of the water pump, when the seals inside the pump fail it starts to drip out of the "weep hole".
Just get it up in the air and look everywhere for leaks. Could be something simple like a loose hose or or bad water pump. Or something worse, Ie head gaskets.

nothing shows up top and I did have it in the air earlier today and all I could see was the wet area on the oil pan and it was definitely coolant

[sunsetorangess]

I would put it back in the air, clean everything you can, then let it run for a lil bit and see if you can tell where its leaking from.

weep hole on the back of the water pump.

so you can test othere cars it wouldnt hurt to buy a presure tester , it pumps air so it under pressure so you see whats leaking with out haveing the motor running , water pumps arnt that bad

I'll end up doing something... Its in the shop right now because my cruise control quit working and I don't really have the time to mess with it myself between school and work.

Forgot to post what I found... It was nothing but a gasket. replaced it and haven't had a problem yet! Still running on the factory water pump. by the way I never saw a weep hole anywhere on the whole water pump.

It's supposed to be under the pulley according to this R+R tutorial:

I didn't check behind the pulley, but as far as everywhere else on the pump goes I didn't see one.

I have the same leak its my freaking water pump

[7camaro7]

I have the same leak its my freaking water pump

if its coming from behind the water pump then don't worry, it's probably a gasket. if its coming from in front of the pump then worry... must be the weep hole.

I just got done messing with my car(installing the Mcleod Clutch Master Cylinder) and while I was under it I noticed there was NO DRIPPAGE! oh yea!!!!!!!!!! I was happy just about that... It likes to shift better now too

[Empatho]

well the car doesnt over heat and it doesnt leave any drops on the floor so Im guessing its just the gasket atleast I hope it is

[7camaro7]

if it doesn't leave any drops on the floor then how do you know its leaking?

[sunsetorangess]

if it doesn't leave any drops on the floor then how do you know its leaking?

Good point, Hmmm

[Empatho]

if it doesn't leave any drops on the floor then how do you know its leaking?

because when I did my under drive pulley I noticed the coolant all around the water pump its just not that bad of a leak

[7camaro7]

strange... did it come from behind the pulley or the pump?
