I want to do just that, install some type of temp gauge to monitor my engines temperature. Do you guys have any tips for install or kits you would reccomend? This would be the first time installing a gauge in a vehicle. Thanks guys at classic olds!!

Were you looking for Water or Oil temp? Either of both can be done. I'm sure some of the folks here can advise the best location to put the senders. I. E. sender location can have an effect on what temp you will see on a day to day basis, although any location will provide a heads up when something is going wrong..

The sender would normally go on in place of the sending unit for the dash light. On your car, assuming it has the 425 engine, that location is to the left of the coolant outlet hose next to the oil fill tube.

In the photo below, it's the thing with the green and black wires attached. Remove this and screw in the sensor for your gauge, route the wiring to where the gauge is mounted on or under the dash or wherever, and you're good to go.

sweet! any idea on a senor that will fit that hole? Yes 425. I see on my dash the spots where it says cold and hot next to my gas gauge.

More than likely, the gauge you buy will come with a sensor that just screws right in. It's a standard size. Any kit you're likely to find at NAPA or Autozone or wherever will include the gauge itself, mounting hardware, wiring, and the sensor.

I put three gauges on my '67 Delta 88, which has the same engine your car has. Below is a photo of the temperature sensor I installed. In place of the connector with the black and green wires shown in the photo earlier, the new sensor has a single wire encased in a flexible sheath.





Here's a photo of the three gauges in the car. Voltmeter - Coolant Temperature - Oil Pressure. I paid $5.00 apiece for them at a swap meet. They work fine, they're lighted as well, and by mounting them under the dash, I didn't have to irreversibly modify the dash itself to put them in.




P.S. Like my Tom Gill Oldsmobile key chain? That was a Columbus-area dealership.

hahahhaha love it. Thank you for the help. Maybe ill attempt installing more than one gauge too

You can also put a "T" in to keep the idiot light sender when you add the new sender.
Most Inboard boat motors have a string of sensors that are all normally open and wired in parallel so that if any one of them close it turns on an alarm.
These are always set up with "T" fittings so that both alarm and gauge sensors are reading the same spot.
This is usually a Transmission temp sensor, an Oil pressure sensor, and a Coolant temp sensor. It's kind of like the ultimate idiot light...

you mean it t's off so i can put BOTH sensors in???

Yep, The only limitation is the space needed to plumb it, look at the threads on the original sender and match them to a short piece of pipe with the same threads. Attach a "T" with the same threads to this and screw both senders in.

This is my 70 350 but you should have some similar bungs on your engine as well. cheerio

Agree, your best bet is going with a triple under dash kit. I put a small Auto Meter set up in my 77', and painted the plastic bracket to match my my dash. Kit includes all the senders, and back lighted.

Actually, one of the SBCs in my boat has a tee that feeds the heater coil in the domestic hot water heater and the other side is the alarm...
