i have had a coolant leak for a while now and have just been re-filling my radiator... well im tired of it and i want to fix it.
the leak is dripping from the bottom of the oil pan kind of to the side..
no hoses are loose and i cant find where its coming from..
im getting a pressure test done tommarow and befor anyone tries to screw me what are some common problems besides hoses??
how and where could it be leaking from?


thanks in advance

 

Waterpump...

 

water pump going bad? or water pump gone bad?

 

when ur car is fully warmed up, is there any smoke that comes from the tailpipe? If so, what color is it?

Blue Smoke - Oil burning inside the engine (blow by)
Black Smoke - Burning too much fuel

WHITE SMOKE - Engine is burning coolant (blown head gasket, damaged cylinder head)

 

there is no smoke at all.. cold or hot i just tried

 

thats a good thing! haha.. no serious problems (as far as not being able to drive it to get it fixed)

Then there must be a leak somewhere. As previously stated it could be the waterpump. Check it for play (movement) if there is play, the bearings are most likely shot and the pump would need to be replaced. Check behind the pump itself if possible, and if there is some type of leakage, the gasket behind the pump is probably shot. Im pretty sure the pump would need to be replaced if the gaslet is shot as well.

If it's neither of these than is gotta be a hose somewhere.

You said that the leak drips down to the side of the oil pan correct? The water pump is right in that area...

prepare for a big bill my friend

 

Only about 400-500 unless you do it yourself for 60

 

lol everything is cheaper if you can do it yourself.

Replacing water pump-

The parts: $75
The Tools: $100
Having the knowledge and patients to do it: priceless

lol

(in case you decide to give it a whirl, or if the mechanic tries to charge you $200 for a new pump)

 

thanks guys ... i will check in more detail tommarow after pressure test...
nice link the is cheap.. i might get one from there if i need one thanks..

 

this happened to me last weekend....same leak in same place...pressure test was good and it turned out that the drain plug at the bottom of the radiator was loose and the coolant was moving along the top of the undercarriage and coming out where the water pump is...check that too.....

 

ok i got the pressure test done and the shop is telling me that it is my water pump.. im not sure how they know that since you cannot see the pump itself..but the prices i have been giving from shop 1 is 450$ and shop 2 402$..

is that bad or normal... im really thinking about change this thing myself but i know it is probly one the most difficult tasks on the 4th gen.. what to do?

Scroll to the bottom it has the writeup for the VQ

Do it yourself meng. Spend the money on some more Mods!

 

Youd be crazy to not do it yourself. Just dont drop anything into the timing cover. Very time consuming and patience
