Duraterm Bosch Glowplugs in a 1.6 TD - Libby!

[deepgrooves74]

So I have read a lot of great things about these Bosch Duraterms (Duratherms). Self regulating, and since it is, it lasts a lot longer... There have also been other benefits as well like better efficiency.
I personally want them for the longevity...

Now I am under the impression that TD's can't run the fast GP Relay, and that there is also a different part number for the slow version of these. This is puzzling since I was told and read that the Duraterms can be used on either circuit (fast or slow).

Can anyone shed some light on this?

Libby I was told by theman53 that you would know... Help!

Thanks folks! I am almost ready to start assembling my car, and since I have been sick I transferred my focus to my motor assembly. Can't wait to fire this puppy up!

Fast is fine on a TD, but if you have slow plugs on a fast controller, they won't stay on long enough to heat up.
Fast plugs on a slow controller  will burn out after awhile.
Duraterms are indeed self regulating, and should work fine either way, but would be an extra electrical drain  on 'slow'
A guy on one of the truck forums ran one on the bench  30+ hours, and it did not burn out.
I switched my TD  from fast Prothe China plugs to Duraterms, and it starts fine just like before.
By my observation, they heat more of the plug to a lower temperature.

Can I come eat a snack off your motor?

Yah see I did a search for duraterms... It comes up, but never said it was a slow version... I think I'm gonna send back the slow relay, and get the fast. Be done with it...

Thanks for the info... You can eat off it if you like... It won't be clean for ever. Just sent the motor/tranny mounts off to the powder coater.

745 summed it up fine.  The Duraterms will work with either relay and either relay will work with any of the engines, but Duraterms are fast plugs so while running them for the full duration of the slow relay won't hurt them, it's longer than necessary to start the car.

Thanks libbydiesel! So I will get these, and acquire a fast relay...

What I don't understand is why they don't recommend fast glow plugs for the TD...

I don't know where you got that idea. Fast (7 seconds) is the factory part for '85 and up cars and there are virtually no differences between an '84 and '85 motor... There is also no difference between the TD and non-turbo with respect to getting the engine started.

Exactly what I was thinking!! Just thought I would ask the question since this came from my local diesel source...

Don't believe anything unless you can cross verify it about six different ways regarding VW diesels.
Other than firearms they are about the most miss-information prone mechanical things I've ever seen for some reason.


Or unless two or three people here agree on it, in that case it's probobly solid advice.

I'm pretty sure fast  plugs are like disc brakes...All manufacturers switched to them  when they  becam reliable and affordable because thy are better*.

* By better, I mean the customer is happy  to only have  to wait a few seconds to start the car, all else being equal

Okay my plugs came in! They are definitely the correct ones! I got them from AZ Autohaus in Arizona. They were $9 a glow plug. The closest price was $13-$16...



They had # 0 250 201 032 stamped into them.





They sold me this relay which I hope is a fast relay. I have not had a chance to double checking on the Internet yet.

Relay is correct, KAE makes decent stuff.

Man there is jack for markup on those glowplugs, my cost is like $7 something.. lol

Good ole Autohauz

Thanks... It is good to know that the relay is a decent one. The guy I was dealing at Autohaus told me that they can sell for as much as $23 per GP. Where did you get them for $7?

[wolf_walker]

Shop cost through work.  I'm sure Autohauz and such pays less but it can't be that much.
