Many thanks to Rixens for both publishing this video and walking me through a glow plug removal to remove an atomizer screen I tore in half during extraction. Rixens has been extremely helpful to me over the few years I've owned the D5WS espar heater that came with my Winnebago Revel. I should probably send them a few beers or a cake or something, but I'm writing these words here as a poor cake substitute.

Thank you very much it's a pleasure to help customers like you!

[@christianben5459]

Thanks so much for your explaination! My D5WS (Opel Insignia 2.0 Diesel) was steaming like hell, now it works justs fine. I switched the screen, gaskets and the glow plug.

[@Wa61105]

Excellent! Just finished my rebuild with your replacement screen & gaskets..

What a great video, many thanks Rixen! Now I will dig into my D5WS and get it fixed (works nicely for 10-15min just to stop). Thanks again!

[@rixensinc.5474]

Do you have any type of code or fault reader?

[@helmsman6542]

@@rixensinc.5474 Nope unfortunately not. Unit has been working great. Ship yard did some repair where they had to disconnect one of the heat exhanger, they swear they let no ari in though.... Can't find any bleeding screws, what do you think about pulling the outgoing hose after the circ pump for a sec?

[@alexwilson4310]

Excellent Thankyou! I never see a video of the heat exchanger being removed from the jacket. I’m not surprised as mine was stuck fast.

Thank you for showing this. The B5WS in the volvo needs a cleaning after 8 years of service. The heater itself is mounted in the factory on the engine firewall, before they put the engine block in, access is pita... wish me luck trying to extract the unit.

[@ilsavv]

🔴 Good luck with that! Car makers sometimes place heaters in very inconvenient positions, it took me a while to learn how to uninstall that thing from a Ford Tourneo Connect.

[@ilsavv]

🔴 Eight years -- it's very good! I have to service my D4WS every other year.

[@petermoller4610]

@@ilsavv I think the difference is that mine is B, so it runs on petrol. I assume it produce less soot than the D variant.

[@alltiallo]

Extremely helpful video. Thank you very much!

[@CriftinsCampers]

Very informative thanks. Unfortunately after a few years exposed to the elephants I find the hardest part in working on these is getting the screws undone one or more are often seized solid especially the long one and being torx the heads are easily rounded off.

What about the glow plug? Very informative nice steady pace

[@rixensinc.5474]

Normally the glow plug does not need to be replaced

Thank you. Good quality video.

[@bonapartistico]

Fantastic video i have the d5wz and is not working: something about the blower motor shorted. My understanding is that the S version has an upgraded timer, but everything should be the same,correct?

[@rixensinc.5474]

The harness has a couple differences also.

[@bonapartistico]

Thanks! Is there any way to upgrade to a 7 day timer or a button to operate independently from the engine?

[@rixensinc.5474]

Yes you can but I'm not a fan of the 7 day timer I do like the digimax D 1000

[@Bobisch]

@08:06 you say screen welds should be on opposite side of inlet. But my Eberspächer D5WS repair manual says the screen welds should be towards the inlet. Confusing?

[@rixensinc.5474]

We see a problem with that and have seen lots of issues because of the position of the screens. If the fuel is entering and hitting one of the Welds it prevents the fuel from Being atomized properly.

[@rixensinc.5474]

In fact the instructions for repairs say the exact same thing I say. under page 34 were it says (please note)

[@miaoxix]

Thanks, very good demo. I have a question, how to take heater from the car?

[@amandeep6472]

Hey rixen thanks for the video i have hydronic 2 d5s 252526 so is it same as Show in this video or what. Thanks in advance

[@rixensinc.5474]

They will be slightly different. We never sold the 2 only the first generation and third generation

[@demil3618]

Ok, that‘s the straigh forward parts, very easy. But how do you remove the fan (w.o breaking it)? Should it pull off the shaft or do you need to remove the stator on the other side and get the fan with the whole shaft out?

[@rixensinc.5474]

Unfortunately there's no real way to remove the fan you just have to replace the whole thing. we sell them on our website for about $280 or a whole new D5WS for $700.

[@demil3618]

@@rixensinc.5474 Ok thanks. Well I‘ve got mine from Ebay for some 50 or so. This was just in case it needed a new motor- and for that one somehow need to separate fan and motor. But maybe that only works by destroying the fan- and replacing it.

[@17shakil]

Thanks a lot sir! Love the work

[@rixensinc.5474]

Thank you

[@celticspirit4001]

I am missing which part is the glow plug? I have lots of white smoke coming out of mine at cold start up, with two cycles often needed before a full fire up. This is all after it was supposedly serviced a month or two ago although we live aboard and use it daily.

[@rixensinc.5474]

Is the atomizer screen getting blocked up? If so We at Rixen's enterprises sell a screen that last much longer than the factory Eberspacher D-5WS screen.

[@smalanningen5137]

What kit should I buy if my heater gives a lot of smoke at startup and often needs a second start attempt before it runs. Also the heat is not good inside the car anymore even if the heater has run for an hour. I want to have the parts needed when I disassemble it. Any advise? Thanks for a great video! 👍🏼

[@rixensinc.5474]

If its a d5ws this is the kit to buy. rixens.com/products/d5ws-service-kit?_pos=1&_sid=5b6e82f7f&_ss=r

[@lappi_wojak]

can I use the car when heater is removed from the car or it will blew cooling antifreeze liquid from the top pipes?

[@rixensinc.5474]

If you take a straight splice, normally 3/4 inch and then connect the 2 hoses together. You won't have a problem.

[@ashleyhaffey1492]

Very helpful 👌 good video!

[@rixensinc.5474]

Thank you for your feedback 😊

[@SimasMc]

what about the glow plug? can you explain more how this heater works and all the parts that can be replaced? Because mine is smoking heavily from the d heater exhaust. so i want to service it, i have a code that says the heater has been activated for too long.

[@rixensinc.5474]

The service shown in this video and the atomizer screen replaced should solve the unit smoking. No reason to mess with the glow plug unless it is physically broken.

[@philipwoodgate4835]

Thanks for very informative video. Please advise on Eberspacher connector pin removal tool, just the dimensions would be of great help.

[@kleinergti1]

Great video. Would this be the same unit on a 15 Mercedes sprinter? Ordered the van with heater booster package

[@rixensinc.5474]

It is very similar to the factory install espar heater on 2018 or older Mercedes sprinter or Dodge sprinter

[@kleinergti1]

@@rixensinc.5474 Thanks. I plan on servicing mine since its been in service 5 years. I will plug the coolant lines and remove mine for service. Curious can I order a thermostat kit and control the unit on my own instead of through the Mercedes switch. I also have a D2 installed and that service was fairly easy.

[@rixensinc.5474]

Its not that easy on a factory installed d5 as Mercedes has tapped in to the unit...

My heater became very noisy soon after service. Is it a bad air blower?

[@rixensinc.5474]

It could need a new combustion fan, Or possibly has some debris in it.

[@gunslinger9352]

Doing a service on my d4ws and manual makes me crazy.. some vids ive seen they pull the glowplug and insert the filter then plug, some just drop it down on plug from other way.. Does it matter? And what is there 2 o rings in my kit.. cant understand where both are supposed to be ?

[@rixensinc.5474]

Usually i never remove the glow plug. Sometimes the atomizer screen will rip in half... Then you have to remove the glow plug. It doesn't really matter which way, I feel that without removing the glow plug it is faster and easier. one O ring is inside Between the fan case in glow plug housing the other is around the end of the glow plug.

[@gunslinger9352]

So one is supposed to be dropped down on glowplug before putting on the filter? I saw one o ring, and that was the one on the housing. Didnt see any more regarding glow plug housing. And factory manual for dw4,dw5 just show one o ring on installation. But 2 one " blue prints" And i never seen a video where someone use 2 of this small o rings, just one on the outside housing towards the burn chamber.

If you follow the wires to the fan Brown is ground black is power put 8 V to it if it spins and sounds normal it works. Follow the wires of the glow plug there's no polarity put voltage 8 to 12 V to the glow plug If it glows red hot it works.

The D5WS has an external mounted fuel pump the filter is inside that pump. The D5WSC has it internally.
