OFHG Change / Coolant Hose / Paranoid about belt?
Hey!
I recently was doing some preventative maintenance and changed the oil filter housing gaskets. During this process, I broke and replaced the coolant hose. I wish I would have known about the aluminum coolant hose flange before, I would have gone that route instead of putting another plastic hose back in. Anyway... I did all of this because I was concerned about all the horror stories from oil dripping on the accessory belt. During the process of doing the gaskets, the oil lines did in fact dump a pretty fair amount of oil on the belt - is this something to be concerned about, or is the real harm a continuous leak and I am just being paranoid? /rant Thank you in advance to any info!

Belt is cheap, just change it for your peace of mind. Most E series cars should be due for a new belt anyway, by now. EPDM rubber is what your coolant hoses and belts are made of. It is not tolerant of fuel or oil exposure. The belt should always be removed if the risk of oil or coolant contamination is possible, which in this case is inevitable.
I have done this repair before with the belt installed because someone before had stripped out the alloy T60 tensioner hole. I covered it with a large plastic trash bag and heaps of rags. The real risk is long term exposure to incompatible substances. A lot of oil filter housing gaskets don't get fixed until they leak onto the belt anyway. Which by then they sling all over the hoses too. The rubber degrades/melts and expands, which then shreds or slips and then ends up inside your timing case. |

If you're worried about belt ingestion, thought about fitting one of these?

Edit: Some pretty mixed reviews on the seller and the part itself. Going to hold off on that item until another solution becomes available.

I doubt there is an 'official' mileage in these days of 'lifetime fill'. I change mine (including tensioner) every 50K...

Yeah every 50k miles. The belts are so easy to change.

It's a good idea, but I haven't seen any of their products in stock since they started the website. Ridiculous. Why market a product if you can't even sell it? I've e-mailed them for when they have them in stock for an N52, but no response.

Sorry Josh, hadn't realised that. Wouldn't have bothered mentioning it if I'd known...

I changed my ofhg, as soon as I took the housing out some coolant went all over my belt. I ended up needing a bolt that unfortunately broke off in the head.. so I ordered a bolt and ended up not changing the belt coolant looked like it had all dried, I've been driving around for 1000km and no slipping and no damage to belt. We changed the ofhg on my friends car same thing some coolant went on the belt.
Waited 2 days for parts, drove the car 200km belt ripped in half but luckily did not get sucked into the front main.. So honestly I would recommend changing the belt to be 100% sure. |
