I've got some questions regarding the Ohm readings from my 4.2L's temp sender....
Bit of background:
Ill admit my bad... The last couple months I was driving my jeep, the temp gauge was not functioning at all..... :/ I know! I know! but the thing is just so dam reliable I took my chances... (fuel gauge wasn't working either so I suspect It burnt out, causing both gauges to not work) I was running a direct drive mechanical flex a light flex fan, and had been for a couple years.
Since then I've decided to upgrade to an electric fan. Why? Mostly because the flex fan was very very loud in my opinion. and a couple other insignificant reasons of my own.
Also, I'm running a regular style rad from a V8 jeep. The COMPLETE cooling system was replaced a couple years ago. EVERYTHING new at that time.
I suppose I did things a little backwords, But I was excited for the electric fan and just finished installing it! and testing out my wiring! It works great!
Thermo switch plumbed into Intake cooling jacket FYI.
But does it cool enough? I started to wonder...
The fan was the ONLY one available from flex-a-light that would fit for me. It was my Only choice, Even though Flex-a-light customer service suggested a slightly larger CFM fan.
Well! I thought... until I get my gauges diagnosed and re installed(I was going to calibrate them both as well (fuel&temp))
I figured I could just throw my Voltmeter to Ohms, Hook it up to the temp sensor at the back of the head, and start er up! Lets see what happens!
So Heres the results!
The time in minutes don't mean much because my rpms and the outside temp and yada yada can all vary:
5:16 176 -Start motor.-motor was running earlier. cool but not "cold"
5:20.50 72 -thermostat opened???
37.9 -Manually turned fan on my self (Ill explain after)
5:36 52 -revved motor 6ish times pretty high.
5:37 55 -Shut motor off...
So........ Does 56 ohms sounds like the correct reading for my motors temp sender? Should I "calibrate" my Temp gauge to sit in the middle of the green at 56 omhs? Am I over heating? lol
Any info thoughts or comments are accepted with open arms!!
