Great video and hard work. You can replace more things while you are there. But guys you can do it without removing the intake manifold too. Just take out the walls/plastic between the engine and heater blower, under the windscreen, and use a 3/8 flexible ratchet and a 22mm socket. You have to take out the fuel rail so you have better access. Took me many hour to realice that it was possible. Did it on my 323i e46. Hope this can help someone as I spent days trying to replace this sensor..

Thank you! I didn’t look to see if there was another way but to be honest it wasn’t that bad removing the intake manifold. I like to see what I’m doing.

@IAMASPANNER i was able to catch the fuel pipe and bend it back slightly allowing the 22 socket to just go straight onto the sensor with 2 long extenions.

Hallo one question please. When i term my car on the fan starting directly is this sensor is the problem too?

@IAMASPANNER Жыл бұрын

A faulty temp sensor could cause the issue if it was giving a too high reading but there are other modules and scenarios that could cause this too.

What a complete ball-ache to get to, but I see why they've done it - the back of the engine is furthest away from the airflow, so it's the hottest part. They're just erring on the side of safety. If you've got the manifold off an M54, for god's sake, replace the manifold gaskets, the coolant pipes under the manifold, and the CCV system - the gaskets are too cheap not to, and doing the CCV without the manifold off is the stuff of nightmares.😁 You might never be in there again, so get as many "while I'm in here..." jobs ticked off as you can!

OK. So while mechanically inclined, I don't know what the CCV is. I'm trying to teach myself to be a mechanic. I'm currently trying to replace the sensor in the video on an E39 530i with an M54. Manifold gaskets are something I hadn't considered but I'll look into it.

@@dennevyn05 CCV is "crank case ventilation" - a kind of loop of pipes that are supposed to take oil vapours out of the head and put them back into the sump. But it is a known weak design, which is why this engine is a notorious oil-burner. There is a way to replace it without taking the manifold off, but it is extremely awkward, and not recommended. Manifold gaskets very rarely fail, but they are very cheap, and you are already in there😁.

Could have just used a crowfoot wrench with an extender, it was made for this type of job and DIY.

@IAMASPANNER 2 жыл бұрын

I don’t have one, I usually do big jobs in a friend’s workshop but this was just a small one. I appreciate that the sensor can be removed without removing the intake manifold but at least everyone gets a better look at it on the video.

@@IAMASPANNER I used a stubby 3/8 Ratchet that has a flexible head with a 7/8 crowfoot wrench and got it off by not removing the intake manifold on my first try. My BF was gonna do what you did in the video and I surprised him by removing it myself.

You can do it without removing the intake. Ive done it on a 325ci a few years back. Lots of wobbly sockets and joints and fiddling but still less of a pain than removing the intake.

You see i bought many many cheap ones , facet, Calorstat, Eps. And all of them made the problem worse. Cheap ones does work but they dont give good readings. I installed those cheap ones, and my car whas reading 103 c instead 92 c. So i got a very sluggish car once the engine driving more than 15 minutes. After buying a good brand Hella, my problems whas solved.
