Hello everyone,
I have two open element GM IAT sensors. I was wondering if I could one as a coolant sensor (CLT) for the ms-II? Or does it have to be a closed element for the CLT?
Thank you

Re: GM Open element sensor as a coolant sensor?
Electrically they would interchange, turbo guys reportedly used the closed-element sensor for IAT as it's more robust.
Haven't heard of anyone using an open-element in coolant, though. I would be concerned about corrosion and whether the wire leads at the 'bulb' are insulated. It might work, but for how long???
I'd recommend spendign the $10-15 and getting the correct one - it's not worth the potential hassles you might face either immediately or down the road.

Needs to get the toes out of the water and just jump off the diving board!!!
current EFI project:
65 Chrysler 300L, 413, working on inline dual GM TBI units, will run with MS2. Hoping to have factory-style appearance.

I thought the turbo guys were using the open element sensor for the faster responce time needed for boosted applications.fury fan wrote:Electrically they would interchange, turbo guys reportedly used the closed-element sensor for IAT as it's more robust.

Using the open element in coolant? I would think the legs on the element would be shorting through the coolant, or at least altering the resistance to give you a false reading. Any reason you want to use the open element?

Thanks all for the responce. Theres no real reason behind using an open element for the CLT, it was just that I had two of them lying around.
It looks like the wise choice would be to stick with whats been done and tested
Time to visit the wreckers!
Thanks again for the help.

You're right, I've read they use the open element but sometimes silicone the the bulb to make it last longer.rusty105 wrote: I thought the turbo guys were using the open element sensor for the faster responce time needed for boosted applications.
