355 Heater Problem

Many thanks TR 512.

Will find the VW valve and get this job done before the baking hot UK summer arrives!

 

Just remember with the VW valve you have to trim the edge it no big deal.

 

I hate to be that guy that revives a thread - but I am hoping someone can help me on this subject.

Based in the UK and currently helping a friend source a replacement Heater Valve. The car is currently at a reputable UK Specialist, but they were unable to source a new replacement.

I asked them to send the Heater Valve back and in the meantime ordered one of the stepper motors from a Saab breaker.

When the original arrived, the partner number on the motor is 005, not 006 and this means that the plug is different to the one on the 006 that I received from the saab breaker.

did anyone else experience this at all? the car is not a UK car as it is LHD, but I have a feeling it was an Italian car. it is a 1997 car.

thanks in advance and sorry for reviving a VERY old thread.

 

If you are referring to the "electrical plug / connector", then no problem, just splice the wires. The motors are essentially all the same with some proprietary mods per manufacturer. T

 

If you look at the Heater Valve packaging in the photo, towards the bottom of page 1 (posted by Johan in Sweden in 2007), you'll see it's from Ruesselsheim, Germany. That is Opel country (HQ). I'll bet with a bit of research you will find it was used on some, possibly many, Opel models and possibly Vauxhall, for you UK lot. I wouldn't spend too much time concentrating on "Saab-sourcing" this part. Try Opel/Vauxhall.

Doesn't help the folks in the U.S. or Asia but maybe in Europe/UK.

PS. and why are you apologizing for reviving an old thread??? no point in re-inventing the wheel

Is anyone able to confirm which terminals are the 1st & 4th? There are 5 pins on the connector and I don't want to put 12V across the wrong ones in case I do damage to the 'new' motor I've bought.

I've actually bought 2x motors (both sub code 917) which allegedly work in reverse to the sub code 944 variants. Anyone managed to get these to work correctly?

Anyone able to help?

 

I also have the 917 sub cade and was wondering if there is an easy way to reverse the polarity? the motor comes apart pretty easily... is it just reversing the correct two power wires?

 

Hi,

Has anyone found any alternative motors for this issue or suggested part numbers? It seems the ones fitted to Saabs are getting as rare as those fitted to Ferraris.

I'll continue searching Opel and Vauxhaul as suggested above, since I agree that Bosch would have made them for other manufacturers.

Many Thanks
Paul

 

Ricambi has a kit to replace the whole valve. It's not plug n plan necessarily as you need to make the connector. The big downside is that it is painfully expensive for what it is. The plus side is it's a solid easy button solution. All the hardwork is done. It works. The bracket is included. I eventually bit the bullet after getting tired of manually adjusting the valve under the hood. Somewhere on here is a thread where I documented the install a bit.

Slightly off topic. Coolant leak at the plastic valve a common problem?


Best fix for this? Just replace with a modified VW unit? Are people modifying the gold lever as well?

Can't say I've heard of valve leaks before (at least not external ones). I have a VW one sitting on my desk at the moment. It looks like the gold lever has to be bent or shortened and the plastic case trimmed.

I can't see any part numbers on the VW part.

(EDIT: https://www.ferrarichat.com/forum/posts/146049409/ )

 

I’m not sure the reason mine is leaking at the lever. It appears I’m the first to report this issue?

Seems so.

Looks like your ad shows a VW item. It has to be modified. Not sure what a "Bosch engine" is (especially on a 348). Just use the link I provided to get the VW number. You may find a cheaper version.
