If anyone has replaced those two O rings on the oil cooler, can you lift the cooler body out and away enough from the engine (after removing the large center bolt) without having to remove the two water hoses that connect on the right side?
If so, I imagine you will not be able to see the small O ring so wonder if one can locate and replace it by feel or just how people are replacing these two seals? Anyone with experience please chime in. I've searched the threads and haven't found much detail on the job and what to watch for.
I purchased the two gaskets at the local dealership and replaced them today. Here is what I can now add to this discussion.
I found a thread where someone mentioned that they were able to flip the cooler body and replace the seals without removing the coolant hoses. He said it "Takes some careful maneuvering, I had it done in 20 minutes. Remember that there is a 10mm nut holding the cooler to the engine block that must be removed too."
I was able to replace the gaskets without removing the coolant lines and I would agree with the time estimate of about 20 minutes.
My large gasket came off in one piece. I used a small pick to catch and lift the gasket about 1/4 to 1/3 of the way around, then I was able to grasp it with my fingers and pull it the rest of the way out.
My Camry did not have the smaller gasket but I went ahead and installed it anyway by just putting it on to the end of the large shaft bolt right as I was ready to thread it back onto the block.
If you are going to do this job without taking off the coolant lines, then my recommendation would be to have very good lighting
and one or two different size mirrors
. You can flip the unit up about 75 degrees - enough that you can see most of the large gasket but not all of it at one time.
That is where the mirrors and good source of light come in.
When you replace the large gasket(seal), there are some small lips that basically hold it in place so you have to get it under all of those lips for proper positioning. I was able to use my fingers to push it under all but about two of the lips and that is where I used the mirror and small screw driver to get the seal under the last one or two.
I didn't remember if I was suppose to lube the gasket before installation (I didn't) but would recommend the gasket be lubed with oil like you do a new oil filter gasket to prevent binding when you torque it to the 58 ft. lbs.
I should also mention that I did not remove anything else except for the oil dip stick so it would not be in the way. I put a bit of aluminum foil over the top of the dip stick tube to keep out any debris. I did hit my hand on the too warm exhaust pipe a few times
anic: so don't try this job until your engine has cooled.
