Autolite GPs Fail

[buddy]

I installed new Autolite Glow Plugs less than 2 years ago and even in CA the hard starting began a few months ago. In this last month it got really bad, but of course it was never so cold that I couldnt start the truck. I would just have to crank for 10-15 seconds on the cold 45F mornings and wait for that big puff of white smoke.

I pulled them all off, and replaced with Bosch Duraterms.

Prior to installing the Duraterms all checked out less than 1 ohm. ONE of the Autolites was still less than 1 ohm, two were a few thousand ohms and the other 5 were all just open.

Is there a specific torque spec for the GPs?

It fired right up beautifully in an instant right after.

So even here in CA where they dont get used too much these Autolites were a huge failure.

Hi,
I am the tech manager for Autolite. If you found five GP's open, you should be checking your glow plug controller before you burn up the new ones.

I don't recall Buddy saying he modified his glow controller or circuit in any way, or it mis-behaving. We in the 6.5 community have had issues with "WAP" glow plugs in the past, symptoms very similar to what he described with the autolites. I've had personal bad experiences with the "WAP" glows, my glow plug controller is stock and performs exactly like the GM shop manual states.
Buddy - Please let us know if your GP controller is acting normal or if the debug procedure autolite provides helps.

Thats mighty nice of you, but I'm not looking to use Autolites again. When the Autolites were installed a new controller was also put in, and the controller operates properly. I have tested the output a good amount, and I get the correct glow time all the time according to the PCM programming I have.

There was another case where the Autolites had swelled, could of been an isolated incident, mine were not swelled at all.

They lasted 18 months, not like they were infant mortality defects from the factory. They had been on a slow decline in performance or dropped out one at a time over about 6 months.

These were the "fast heat" variants.
