Oil cooler
Replaced the 2 oil cooler gaskets today, if anyone tackles this job them selves I suggest to drain coolant a little bit then take off the coolant lines going to cooler. It gives u more room for the one bolt.

I took my 2011 GL350 in for oil change at dealership last week. (First time since purchase so I thought it would be good for them to give it a look over) Tech came back and said I have leak at oil cooler. I have not had any oil detected on floor of garage. Also, last oil change was conducted at 81K at dealership, vehicle now has 89K. Oil level was approximately 1 quart low when checked prior to trip to dealership for service. I have a couple of questions.
1. How did you know when it was time to change the cooler seals (i.e. how much oil were you losing)?
2. If it is only seeping, wouldn't you think I could monitor that and add if needed instead of having them tear apart my engine to replace the oil cooler and seals for >$3K?

All the oil coolers are the same from 1999-2008, mine was sweating and making mess it was not dripping on ground, I do all my work the gaskets cost me 20.00 and 22.00 Canadian right from dealership, took me 1 hour. There are videos on u tube that help
