Thumbs up Re: coolant temp sensor

I used the spacer in the back of the passenger side head for my gauge.

After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: coolant temp sensor

Where did you put the one for your fans then?

I have my fans on the back of the passenger head, the ECM on the front of the drivers head, and then my guage we were going to weld a bung into the water pump but we haven't done anything yet. For right now I'm just using a bluetooth OBD2 scanner with my phone to keep an eye on it.

What gauge are you running? That will be a factor in what sender you use.

Wink Re: coolant temp sensor

The fans are controlled by the ECU which feeds off the sendor in the drivers side head.

Re: coolant temp sensor

Call me a chicken, but i didn't have enough balls to drill and tap the head to a 1/2" NPT. So i drilled and tapped the water pump.

Re: coolant temp sensor

Autometer makes everything you need, if you search my username there's a thread I posted in that contains all of the part #'s you need to use their adapter and sender with the stock 67-72 gauges.
I have one in my truck and the gauge is nice and linear in it's action and about vertical at 210* which is exactly where it should be with these motors.

Re: coolant temp sensor

The PO stripped the hole in the front of the drivers head, so I drilled and tapped it to 1/2" NPT and put the stock 5.3 sensor in the rear of the passenger side. It was pretty easy. I put grease on the bit and tap to keep the bits of aluminum out of the head.

Re: coolant temp sensor

I did the same as Andy. Drivers side is for PCM which controls fans, pass side is for gauge. I actually get a different reading between the two. It's been as much as 20 degrees at some times.

Talking Re: coolant temp sensor

I also have the scan gauge 2 in the truck so I have 3 readings and yes the passenger side is always higher than the computer readings about 18 degree most of the time.

Having a sensor in back is no different that the one in the front of your driver side... No... no negative effects.


Guage adapter after removing the passenger side rear cylinder head OEM fitting is: (m12x1.5 - 1/8" NPT)

Autometer 2277

Re: coolant temp sensor

Yup that's^ the same thing I did. And good to know I'm not the only one with temp variation between the two. I'm not worried since my e-fans run off the pcm anyway so when I check my gauge I just look at it and subtract about 15 degrees in my head. I haven't had any overheating problems since the new rad anyway though.

Re: coolant temp sensor

Took the stock temp sensor from my 91 350 had it milled down to fit the passenger head, plugged right in, voila.

Re: coolant temp sensor

Good info!

What 1/8 npt auto meter / vdo sender works with our 67-72 gauges though. With the Autometer. 2277?

Thanks! Should help the OP as well.

Re: coolant temp sensor

Does any of the late model cars/trucks use an idiot light. I am installing a lc9 in my 70 swb and just want to get a switch to make idiot light work. The right head is plugged on the back with a m12x1.5 bolt and washer.

Thanks

Re: coolant temp sensor

Wouldn't the adapter keep the sensor/switch from going into the coolant?
