Thank you. If your belt is showing signs of wear and you have no oil leaks from the oil filter housing area then that is exactly what I would do as well.

[@NijoR873]

Not doing this anytime soon but will definitely look back to this video when this oil leak arises on my M235i. It is honestly an amazing video and the amount of effort that has been put into this is extremely impressive. Well done and thank you for providing such useful videos!

[@FritzRamos]

Thank you for that, I appreciate your kind words and support. I wish you nothing but good times with your M235i

[@Tluchak14]

Ironically, I just installed the Mosselman thermostat on my 235i this week. I didn’t go the full route of replacing the OFHG, so it was a quick 45 minute DIY for me. I drive highway to work every day, so the last bit of info was helpful for me knowing it’ll just help me with longevity (currently I’m closing in to 110,000 miles). Thanks again for another helpful video.

[@FritzRamos]

Thank you. What made you want to upgrade it?

[@Tluchak14]

@@FritzRamos The main reason is for overall improvement to the reliability of the engine that comes with the lower oil temperatures. I already have what most to be considered high mileage and I plan to keep it for a few more years, so reliability is important for me.

[@FritzRamos]

@@Tluchak14 that's the same reason I got it! Good to hear I'm not alone😅 Hope it serves you for many more years to come

[@lucaalux]

I upgraded my thermostat with Mosselmann. Paired with MHD sport cooling mode. Now my engine operating temperature are: coolant from 85 to 90 Celsius, oil from 93 to 104 Celsius degrees. Before that coolant was 105 and oil 118 Celsius deg. This mod improve the life span of all gaskets and timing chain tensioners. I am mechanical engineer but not an engine designer, just my concern is about lowering temperature will thighs tolerance between pistons and liners. main goal of bmw designer has been set this temperature so high for emission homologation and fuel economy. Good job Fritz, I appreciate!

[@FritzRamos]

Thank you. All very good points and very detailed 👍 I suppose we'll have to monitor the situation over a longer period of time to see the full results

[@DigitalDissident]

I did this for my E82 N55. Now it runs 20 degrees cooler than stock. Also went with a better silicone gasket. Was a big effort with lots of steps to do in my garage. Worth it. Thermostat, fan speed setting, intercooler, & M3 cowel conversion all combined results in significantly lower engine bay temps which extends the life of your components.

[@FritzRamos]

Well said and thank for sharing your experiences. Where did you get the upgrades gaskets?

[@johnnyartiga3028]

do you mind telling me what fuse you pulled i’m currently trying to figure it out and can’t find any info on usdm 135i 2012

[@DigitalDissident]

@@johnnyartiga3028 When I pulled the fuel pump fuse, my engine fired up for a few seconds anyway. So take out your ignition coils. My cars been running fine though. I don't remember what fuse it was

[@kencorwin8341]

As I noted on your other OFH housing gasket video, the problem with using the 12-point ratchet on the E-torx bolt head is that it easily strips the bolt head and makes it much tougher to remove. Much, much tougher. Hours of tougher. If that bolt head gets stripped, your estimated 90-minute hour gasket replacement job becomes quite an ordeal, given how already-difficult it is in the first place to reach that bolt and get leverage on it. So, when you get to the point that you’re about to remove that small bolt, first disconnect and move aside the cylinder head temperature sensor and the hose just beneath that sensor. These are located at the front of the engine, just to the left of the OFH. When you pull the sensor clip, do it **carefully** as the clip can fly away, it’s not secured around the sensor. The adjacent coolant hose is attached to the engine via two simple 8mm bolts; just be firm but always gentle when pulling any hose. With these out of the way, you can fit a proper ratchet wrench with E-torx socket onto that very soft bolt head and avoid stripping it.

[@johnnygonzalezperez2346]

Thats what i just did, worked! I couldnt unbolt that little one even with the 8mm so i disconnected the cylinderhead temp unit

[@geemoney9533]

Great job I had to do this for my bmw but I also changed the gaskets in the manifold

[@richardggeorge]

Unlike the Keis Motorsport version of the same instructional video (which is 37min long!) you stated with the most important step FIRST, i.e. pulling the low pressure fuel pump fuse and running til it stalls. Don't want to lunch your engine! Edit: not sure if you want oil/coolant temps below 90degC for prolonged periods though as this may increase friction in your engine. This might be more of a track-only mod.

[@FritzRamos]

Thank you, but I did have the privilege of watching Bryan's video and making some changes and applying it to this project. If I remember correctly they also changed the gaskets on the manifold and did a belt replacement. So I just hope that the next person to record this job touches on a point that I missed or does a better job overall. Good point at the end there, I was thinking about that too. I suppose as things progress I could make an update video.

[@FritzRamos]

Thank you! Glad you enjoyed it!

[@TheHunterHofman]

Good content, Fritz. I'm just not sure about the thermostat's purpose. It does lower the running temps when driving normally, because it opens earlier. However, the oil used in our cars is designed to be used at 105 - 115 degrees Celsius, meaning that there isn't an issue in the first place, right? It feels a bit like creating a solution for a problem that isn't there. So if you then track the car, this thermostat won't save you either, because it does not improve the flow of the oil to the oil cooler. On track it does exactly the same as an OEM oil cooler (apart from opening slightly earlier, slightly delaying your oil getting (too) hot). A more viable option would then be to get a larger oil cooler so that more volume of oil can be cooled, or work on improving the flow to the oil cooler. What are your thoughts on this? Again, great video and look forward to the next one.

[@FritzRamos]

Thanks and that was my train of thought before installing it but after testing I think perhaps there's additional passages or wider channels in the MSL thermostat that allow it to sustain those lower temps. All that is unofficial, but I can't think of another it achieves the sustained lower temps. If you have another idea I'd love to hear it. As far as lowering the running temps, I was thinking that any heat above operating temps is excessive and can cause additional stress on gaskets and plastic components so reducing that would be beneficial to the other components. However someone brought up a good point of the excessive heat being used to prevent gunk build up on the intake valves so I suppose it has it's ups and downs. There definitely needs to be more testing over a longer period of time. As things progress I'll be sure to share my findings.

Thank you for this! I do have am interesting and quite possibly a critical question. I am hoping that I am overthinking this but do not want to risk blowing up my engine. I have a 2016 435xi that started leaking a significant amount of oil from the thermostat to the point the engine started smoking and the ECU spat out a Drive Train failure. The belt did not slip. luckily I was in my driveway. Please keep in mind I did pull the fuse mentioned in the video however I did not even get a full minute in as I started panicking. My question is, should I just drain the rest of the oil or top It off after installing the new Mosselman thermostat based on the fact that I did not get a full minute in. I understand this might be a duhh question but do not want to risk anything.

[@FritzRamos]

If the oil is still good, just top off and thoroughly clean the area. Was it the new gasket that failed?

[@77cvalle77]

First off, thank you for the response! I've been full panic mode since Monday with this is specific situation . It just so happens its due for an oil change. Please keep in mind it lost a significate amount of oil for what its worth. Still suggest to top it off or am I risking it by draining and full service? Regardless of toping it off or full service should I plug in the fuse before starting the car? Please keep in mind the car ran as stated less then 30 seconds with the fuse pulled, from there the car has yet to be turned on. Sorry If I caused any confusion, the failed part was the original gasket. The new new Mosselman thermostat came in today, waiting for a new belt and pully as there was a lot of oil on it and well, I am there already might as well. PS- you are spot on the "MVPs" tools needed. Thank you much in advance and yes, I understand you are responsible if the engine goes FUBAR :)

[@FritzRamos]

@@77cvalle77 If you have the car in a safe place I wouldn't turn it over until the job is done. Keep the fuse out I would start by cleaning the engine bay of any oil and dirt that leaked and be very thorough. Then do the thermostat and gasket job. Third I would do the oil change but pour 1-2 quarts directly in to the oil filter housing and observe for leaks. This is be very tedious and time consuming as you can only add in a little bit of oil at a time. If you're leak free, then change out your belt, tensioner, and pulley. Once the car is ready to run, try to turn it over twice with the fuse OUT. Then you can put back in the fuse and you should be alright Just check for leaks as the car is running.

The question is why would BMW engineering choose the temp they did for when the thermostat opened and sent oil to the cooler. If there are no cons to opening the oil t-stat at 20deg cooler, why wouldn’t BMW have done this OEM? Not saying you’re wrong, but questions like this need to be considered.

At what mileage interval do you expect the gaskets to get replaced? Is the 40k change part of any scheduled maintenance? If not, should a second owner who gets the car past 50k miles do the oil gasket replacement anyways?

[@radiomaster200]

I noticed that you didn't prime any gaskets with oil. Do we not want to do this?

[@FritzRamos]

I suppose you could, I don't think it would be bad if you do. On the opposite side, if you have oil on your hands and it gets on the gasket you don't necessarily need to wipe it off. O-Rings in a oil change get spun in and rub against the housing until it's fully seated. So the priming them with oil helps reduce friction to prevent tearing or ripping. The gaskets in the oil filter housing are just pressed in so it's less critical to prime them. At least that's how I thought about it, but if you find more information please share it.
