Aftermarket temp gauge?

[colelkhunter]

So after replacing the thermostat on the 931's NHC 250 and having zero results, the problem has been the gauge or sending unit all along. Temps read with a laser thermometer have not exceeded 150 degrees on several locations on the engine and radiator. After searching here and reading up on the topic, it seems this is a common problem. I have also seen aftermarket gauges installed on builds and engine swaps, but not a topic discussing it. I was also not able to find anything related to this in the Tm's Those of you who have done it, what have you had success with? Was it a PITA? I am planning an autometer temp,trans temp.EGT and oil pressure. I plan to drive the truck on camping trips and these are the most important vitals that I want an accurate reading on. I plan to use mechanical gauges so no worries with the 24v except with the EGT i think.

A mechanical water temp gauge will most likely require a deep well for the sensor.

I have replaced quite a few(owning a dozen or more trucks)stock gauges and or sending units.

I have never had any of the new replacements fail.

Diagnosing your problem, is not hard to do(covered in the -20 TMs).

Fwiw, I would just replace with stock items.

I have not priced any of the stock replacement parts as of yet, but it seems I will also need a trans temp sending unit or gauge as well as the coolant temp. Both are available locally in an autometer brand for 39.00 Thanks for the info on the deep sensor. i think that may make a difference in getting the right sensor.

Send tweeter166 a pm with your part numbers and he and bet you brand new nos gauges and senders.

When my sender failed I went to Napa and asked for a Stewart Warner mechanical temperature gauge. I did not need the deep sensor well for it. It works great but the tube going out to the sensor is a little short and I couldn't route it the way I wanted.
