Another oil cooler bolt sheared

[davel501]

My dealer dug a broken bolt out of mine and replaced it as well as replacing the other a few years ago. I wanted the entire coolers replaced but they only did the bolts. It has been fine since so I would say start with the bolts and go from there.

So, one of my bolt heads popped off recently. I dont appear to be losing any oil, yet.
Wondering if anyone has any detailed pictures of the oil cooler disassembled?

Also, wondering if i can just drill the hole through the cooler completely and put a nut and bolt on it, torqued to the cover bolt specs? All this bolt does is hold the cooler cover on, correct?

Here are a few pics. One with the oil cooler apart with a remaining sheared bolt in the cooler and one with a sheared bolt remnant out after a screw extractor used.

Did you ever drill through the oil cooler and bolt it together? There are 4 bolts on the backside of the oil cooler as well, so your idea has some merit. I would also suggest replacing the hose clamps to ratcheting clamps on the cooler as well because the port side factory clamps are difficult to get to.

@Ronnie and @kthrash I am approaching 200 hours on my 2010 and i havent had any oil cooler issues, yet. I check them weekly, during the season. At any point can i assume i am either out of the build date range when this was a problem or is it a ticking time bomb?

My cooler bolt’s just snapped this season, 450 hours on the engines and still running strong

I took my factory cooler and drilled and tapped the bolt for the upgraded larger one.
