Coolant Leak ! Looks Like Its Coming From Sump/oil Pan

[dantheman88]

hey guys

Just noticed I have a water leak. Its not any of the hoses as they are all brand new braided hoses. It looks like its coming out the sump oil pan area. See Pics...

Would this be a rooted or leaking water pump?

If I need to replace it, should I be doing the timing belt and eveything as well? Or can i just do the water pump?

The factory oil/water exchangers is around that location, it deals with engine oil and coolant.. the coolant side of it might have failed.

[dantheman88]

is there anyway to check it? and what would be involved in fixing it?

[theponyremark]

It would involve checking if the oil/water exchanger is faulty. If it is, you need to go either to a wrecker to find a OEM one or just get an aftermarket one from a place like JustJap.

is this the water/oil exchange your talking about?

I have the same as the one above with the remote oil filter and oil cooler and completely bypas the exchange

Anyone?

Wash of the whole area, run the car on stands and have a look and see if you can see where its coming from. It could be runing down from higher up, could be a waterpump or something from under the cam covers.

It looks like it is coming from the oil dip stick among other areas. There is actually quite a bit which worries me

[dantheman88]

does anyone think this could be a head gasket or cracked head? or would that result in oil in the coolant?

You need to do some investigating and try to track it back to the source. Have a look at the leakage indicator on the water pump to rule that out, it's a little hole underneath where the shaft comes out of the pump.

it doesnt look like there is any leaking from the pump. it mainly looks like its coming from around the dipstick and the front of the engine where it joins the sump

Do what eightsixboy said instead of wildly trying to guess what the issue is. You will know the exact location of the leak and diagnosis will be far simpler. People can tell you whatever you want to hear but unless they know for certain where the issue is you will just be wasting time and money fixing things that aren't broken.

If you have a N1 waterpump, they can leak out the elongated hole if not sealed properly.

If it's accumulating around the dipstick it might be a hose or the fitting that comes off the side of the thermostat or the thermostat housing it's self. The coolant would be dripping down from somewhere around there.

Start up your car and give the coolant a chance to leak out then get a small mirror and a lead light then do some looking around the thermostat area.

There is about 6 joins ABOVE the dipstick. Start cleaning it, then inspect. Get a torch and a mirror.
