Have you flushed it before? IIRC its every 7,500 miles for a flush or every 4-5 years.

I don't think the previous owner ever flushed the coolant before. I honestly don't know what maintenance was done to the car before I bought it back in November of last year.

Ahh that sucks, I am currently having to go through that on my truck and iron out all the small problems from the lack of maintenance from the previous owner lol and there is no time like the present to start catching up on maintenance (money allowing of course lol)

Well I just took my reservoir off and flushed it. Full of oily sludge. I also notice oil dripping in the exhaust flange. It's definitely coming from the housing and not the valve cover gasket or the oil filter cap. I smelled it this evening.

I will take off the heat shield this weekend and take a look

Just to add, my reservoir saw completely full of light brown sludge, when I took off the lines to the reservoir those were also completely lined with the same sludge. I just ordered a new oil cooler as well as new inlet and outlet lines. Hopefully the parts will be in by the weekend. I will update this thread as to how I make out.

Ok oil cooler changed

It's pretty simple. It's right behind the exhaust manifold.

Steps:

First remove heat shield. (Pita).



The loosen all exhaust manifold nuts (10mm)

Unplug O2 sensor

Remove 3 1/2 nuts holding exhaust pipe to cat. (Cat is part of exhaust manifold)

Remove two 3/8 head bolts holding cat to engine, underneath by flange.

Remove dipstick tube, it's an o ring that holds it in. Drain oil first before removing dip stick

Remove exhaust manifold. I also removed both engine hoist points (12mm head)

Once manifold is removed you can see the oil cooler. Remove 4 t-30 screws from the tubes, one at waterpump and one at thermostat housing.

Remove 5 3/8 bolts from cooler and slide off last tube leaving it in place.



You do not need to buy new tubes but... get all new seals from the dealer. Like $10 in total

Make sure rubber seals come off with cooler

Then clean everything

Then replace cooler



Re attach tube to water pump and thermostat housing

Install manifold.

Bolt up flange.

Re attach o2

Add coolant and oil


While everything was apart I cleaned all threads with a tap and die

Everything was put back together with anti seize

All in all I had zero frozen nuts or bolts and took about 2.5 hours to change everything over

Hope this helps

How cool can it make the oil if they located behind the exhaust manifold and under the heat shield ?

Who knows. I think it's kind of a poor design myself

Just a 300 mile update. Coolant is clean as can be. No more sludge or anything in the coolant tank
