Thermostat Gasket or OFHG?

weehe126 · 12-03-2014, 08:02 PM

Took a look under my hood for an unrelated reason and noticed a decent amount of oil splatter around the OFH. I took some pics, hopefully they help. Looks like the belt was flinging the oil onto the charge pipe? Before I start ripping into it, just wanted to get opinions on if it is just the thermostat gasket or if it actually is the OFHG.

You might as well replace both, your already their. No sense in doubling the work later down the road.

Was just looking them up, is that the oil cooler gasket, not a thermostat gasket? Just going to get it out of the way.

That's the oil cooler gasket..the engine thermostat is located next to your electric water pump underneath the engine near the left front of the vehicle.

Thanks, not sure why I thought that was where the thermostat was. Looks like I have a fun project for the weekend

So does anyone know where I can get the replacement bolts for this since they are one time use? I found the gaskets on ECS but not the bolts. thanks.

He actually means right front of the vehicle. The picture is of the left front.

i literally just did this last weekend. buy both gaskets, the one i originally thought was leaking, wasnt the one and you cant really tell til you open it up. if its been going on for a while he will probably want to replace the serpentine belt as well

I am going to replace both and the intake mani ones to be on the safe side. I just need to find a place to get the bolts that I will be removing. I want to do it right so want to get everything new. Or can I only get them from the dealer.

The bolts are steel, their reusable

Got mine from rockauto and its been 4k and no issues after replacing.recommend trq to spec,and do not over full oil or it will seep through the gaskets.happened to me once

Sounds good thanks. Had thought I read they were one time use.
