Tips on installing water temperature gauge

Hello I was wondering if anyone had any tips on installing a water temperature gauge. I have an 85 CJ 7 4.2 Litre. I am not very confident on the factory gauge that it works as it should as it seems that it stays in the same spot most of the time and Jeep does not have an overflow tank. I plan on buying an Auto Meter gauge and installing that to get a more accurate reading of the temperature that I am running. Any help would be appreciated. Thanks

My question is why wouldn't you have an overflow tank? As for the factory gage, if you pull the lead wire off the back of the block/temp sensor and ground that wire when you turn your jeep on the temp gage will immediately peg itself to H if it is working properly. If not then the gage is not good. That's a quick way to test your gage if you think its not opperating properly.

Installation of a new gage really is pretty straight foward. Goodluck with the installation!

There's a threaded hole on the block, driver's side just forward of the motor mount that accepts the aftermarket sending unit. No need to cobble it and blow $23.

You can also remove one of the temperature sensors for all the emissions crap on the side of the intake and install a mechanical gauge there.

The fitting goes right beside the thermostat so you would get a more accurate reading,

CJ 8 Extreme I purchased this vehicle not to long ago. There was no overflow tank installed but I might just install one. Is it really needed though? I want to install a mechanical gauge just to make sure that I am not running hot and damaging the engine. Thanks

Ah I got ya, I've always needed my overflow tank . A cheap infared Thermometer from Autozone for 10 dollars will give you a quick reading on your temp under the hood. I keep one of those around in my glove box to help track down problems under the hood.

The last autometer gauge I bought just required finding a place to mount the probe for the gauge. I tappd a new hole for the probe near the thermostat as mentioned above. For ease you can probably use the orginal hole in the back of the block if the threads are the same, I can't vouch for that mounting spot because I did not use that one.

Splitting hairs really, but I wouldn't have the room on the boss that's on my t-stat housing to put one.

Did you ever install your water temp gauge?? I have a 84 cj7 and it came with a aftermarket water temp gauge but the wiring is all messed up, i need help with connecting the gauge on the right way, what wire goes where kinda help? i can find any diagrams for that for some reason..

Purple with tracer from the top of the sensor to the back of the temperature gauge.

The power was a shared red wire, there was one connection for the fuel and temperature gauge. It is unknown as to where your power is coming from for the new gauge but I suggest finding one that is linked to the IGN LPS fuse in the fuse box, probably red.

Depends which aftermarket gauge he bought. Some still use the regulated supply from the fuel gauge.
