Installing an Aftermarket Temp Gauge

[rousie13]

How involved is it to install an aftermarket temperature gauge? Will the gauge include everything you need for the install? I don't trust the stock gauge and with a manual switch for my fans, I want to know the exact temp.

well, maybe if you had a specific unit in mind, it would be easier to answer your question.

actually, flex a lite makes a temperature switch that i installed in my uncles cherokee. i removed the mechanical fan and ac fan, installed dual flex-a-lites, ran a relay to energize the system when the ignition is on, and the temperature kit includes a sensor on copper capillary tubing that you insert into the coolant flow. the capillary tubing goes to a microswitch assembly that has an adjustable on/off point.

i placed it on the hot side of the radiator so as long as the engine is under load, the fans are running.

The temp unit in our cars is elec. and a mech. gauge gives you a better reading. The temp. sending hole is 12 mm and most gauge kits come in standard so you'll have to find a 12mm fitting. Then it's just amatter of installing the gauge and routing the copper capillery tube to the front of the engine where the top rad hose comes in. Try to keep the tubing away from excessive heat. Autometer and sterling make nice mech. gauges. Both gauge companies supply all hardware but once again make sure it's in metric. Hope this helps.
