Coolant temp sensor - what is a good replacement?

[someotherguy]

I'd probably buy this one, from SMP https://www.rockauto.com/en/moreinfo.php?pk=40549&cc=1353451&pt=4748&jsn=552

Weird that this one isn't available through Amazon.

Every time I look at my sender, I hope I don't have to remove it. I'm betting it's pretty well stuck with all the heat cycles it goes through.

I wonder what changed from the TBI to Vortec 7.4, as that's not the part # for the TBI application. Mine has the correct connector on it without an adapter (and is also a SMP item, # TS265) ... seems to have been working fine so far, delivering readings matching what I'm finding shooting around the cooling system with the IR temp gun, which I did quite a bit of after replacing all the hoses, thermostat housing, heater core, and the near disaster with the already-broken and gooped-over heater hose connector.

I have this one coming from Amazon. I got it just based on looks, so not positive that it will fit. I'll find out in a few days!

Standard TS375T looks like the one for a small block Vortec.

It very well could be. Curious as to why GM used different ones.

The wise thing would be to stop the delivery, and order the right one. I've never had to stop a delivery, but I've seen the option on Amazon.

If hasn't shipped yet, it can be stopped. If not, just return it.

Often but not always. If it’s from a 3rd party they can’t or won’t always. I’ve tried sometimes when it still says “Preparing for Shipment” and they still refuse to cancel. Either way, it goes back after I get it.

I'm going to wait until it gets here and see what the difference is. I'm sure it's just thread size.

I always assumed the pigtail was to keep the weatherpac connector away from the exhaust heat. The wire doesn't seem to come off the sensor.

This one did the trick! I crimped a spade connector on the harness and hooked it up. Easier to install too because I could put a socket over it.
