I know in order to hook up their Ultra Lites, you need the adapter and sender for short sweep guage to mount to LS heads. But are those also needed when hooking it up to after market heads? I have Trick Flow 235 heads? Thanks

I drilled and tapped the passenger rear coolant port that was blocked off for use with a mechanical guage.

I'm running something like this below. Its not exact but they are all over ebay. I also drilled and tapped another hole for the steam tube to attach to instead of routing it to my water pump or directly into my radiator.

I assume it doesn't matter which hole I have the sensor in right?

I actually drilled and tapped a hole in the top of my thermostat housing and screwed in a 1/4" hose barb to attach my steam tube to.

this will be my 2nd option. I like the sender in the head as it keeps it hidden

got new sensor and adaptor. could also be getting interference? everytime i put a new load on, like turning on 2nd electric fan, my temp goes up.

I know not to put telfon on the adapter that goes in the head as that has the copper washer but do you put it on the sensor that goes in the adapter?

Yes, the sensor has pipe thread and needs the tape.

I still seem to be having flase readings. Highway driving it stays at 205-10 then stop and go drops to 190. Now I am guessing it is electric interference as the temp drops when my volts drop. Going to check the ground tonight. Should I ground it right to the engine?

99VetteFRC

That may not be false readings... You may not have a large enough radiator or enough air blowing through when driving.

it drops temp when sitting still in traffice and then goes up when highway driving??

plus I out a temp laser on it when it was reading 210 and the gun was 180

wait, did you say you did or didnt put teflon tape on the threads? I was told not to because it gets its ground from the head and the tape would interfere with that. im no expert but it works for me

edge04

no tape on the adapter or sender.

what temps are you guys seeing that are running the adapter in the rear passenger head?

I also notice that mine will read 5 degrees lower after getting up to running temp and then shutting the car off and restarting it, then when starting it from cold??

Maybe I should take the teflon off or add another ground?

Can you guys share what temps you are seeing with this set up? And if any of you expereince what I do above?

Other day I was in dead stop traffic, 80+ degree and sunny and my guage got up to 230. Once moving it dropped right to 195 and stayed.

I assume all these factors will give me a higher reading: Maggie SC, reading off rear of head, rear ports tied to front, electric water pump.

Would lowering changing my t-stat to a 160 help??

iTrader: (9)

well not many responses lol. But I just swapped in a 160 t-stat and drilled two 1/8 inch holes in it, let's see what that does.
