Coolant Leak from rear of engine

[youknowmyname67]

check that line on the back passenger side corner of the intake the heater inlet hose that piece if it cracked or broke leaks bad enough to cause instant over heating etc

I vote intake manifold gaskets.... notorious for leaking on the vortec motor. When replacing, get the Fel-pro part number listed in my signature.

Isn't that on the front on Vortecs??

Hmmmm WRX???

It is a 01 Forester, I put head gaskets and a waterpump on it last year but did not mess with oil pump while I was there, so this spring I get to do that piece of it

+1 This is what I had to do about two weeks ago on my 96 Yukon.

It was the intake manifold gaskets.
I finally finished putting it back together last week and drove it back out of the garage, now to fix the other issues...

Congrats, its not too bad of a job.
What other issues are you having?

Now that I look at an intake gasket again you guys are probably right. I thought the intake ports were furthest back ...

Thought I would pop back in and give an update

On mine the rear of the intake manifold does not have a coolant passage, so the gasket set has material covering the hole in the block on each side. That is where the coolant was coming from. It was probably leaking on one side slow that progressed to both sides fairly well. It took a year to eventually get done, but there is a new water pump, idler,tensioner, Plug wires and thermostat on it as well.

I do have a valve ticking on number one, and a door handle repair to complete before I can get it inspected and allow the wife or kids to take off in it

But I have a new toy that needs work too, a 2001 gasgas 321 trials bike, so there may be a bit of a delay again

guess what I'll be doing next weekend on my '97 4x4 4 door Tahoe, not particularly looking forward to it, wonder if anyone has step by step instructions written by a human and not Haynes or Chilton
