Does the valve itself usually get hot? I tuned my 325i on and it's very hot ( the valve itself)? I have connection just wondering if it should b replaced, don't know if this exploded my tank
...why did you remove the press release clip from the MAF. just disconnect the intake duct from behind it and release the MAF via the metal spring clips in behind the airbox. you don't need to drain the coolant, clamp the hoses to the valve using gator grips and a rag as not to damage the hoses. Disconnect the valve connector from the relay portion of the valve and then slide it out of the hoses. replace it and reverse the steps. Common issue with these are deposits on the shaft internally holding it in the open or closed position as the actual relay becomes aged and weaker.
If I suspect a malfunction in the water heater valve is why I'm getting mixed hot and cold air when using the AC, would simply unplugging the valve potentially fix my issue?
@@EnvyInMotion it'd be more of a headache, use a pair of vise grips to clamp the hose running into the cabin shut until you can purchase and replace the valve, ziptie the visegrip handle so it can't pop off and make sure they don't foul. This is in case of an emergency (unable to defrost or similar situation) or to diagnose the HCV.
I gave my heater valve a clean and grease. I will if this improves my heating problem. I can be driving for say 20 minutes and then the heater suddenly pushes out extreme heat regardless of the temperature setting. I will let you know how I get on and if the problem is fixed.
Did cleaning the heater valve solve your problem? I am also experiencing the same heat coming from the foot well regardless of temp. setting. I was thinking of replacing it, but I'd love to save $100 if I could just clean it...
@@EnvyInMotion hmm, It's been some time now, but I think this may have fixed it. I don't seem to have the issue anymore. I don't remember if this was the solution or something else. Sorry. I know I replaced a lot of the cooling system hoses, including those underneath the intake. Idk if that was before or after this cleaning job. Good luck!
Hello everybody, Do you think, the aux heater valve may affect on the duration of the engine warm-up? I have these symptoms of long warming up of the engine (bmw e91 330 xd, manual gearbox). I’ve changed both thermostats and it’s still like 20 mins (in spring time ~ 10 deg C ) to get to the 88 deg.. According to the Realoem the specific item is called: Changeover valve p/n: 64126951814 Regards
Yeah! You great master, with your instruction i´ve fixed my 330D!! no more heat on footrest, thanks!!!
I have e46
With ac on on foot get very hot up vent are cold, this will fix my issue??
Thank you.
Great video, I'm going to give it a try. What kind of grease did you use?
Great video . keep the great work
Very useful film, as i have to do mine ASAP
good educational video.
Thank you 👍🏻
I have no coolant coming from the bottom hose of the heater valve. Can you help ? My heater is blowing cold air.

Why do you need to fill it with water? That bit is unclear to me. Surely too you need to refill the coolant system?
Did you ever find out why or if it is even necessary?

hello, good vid, you use just water from in the can you put in? or coolant???
thanks
+rondjeee water is fine to clean it, then distilled to flush the mineral water out.
+Megan Berry thanks, much water comes out when taking watervalve off,or not su much?
drain the coolant first?

@@mikehitabranch did you eventually fix this? I'm having this exact problem

Gwei Lao, gwei lao!
why the hell did you put water inside ?
Why did you fill the solenoid with water?
To prevent air trap in hot water pipe, BMW hot water pipes gas are very hard to de-gas it

This device should have NO affect on the duration of engine warmup. It has nothing to do with engine temps, only interior heat.
