Temp gauge installation

[JoeMarine]

I plan to install a lower water inlet with a port to install a water temp gauge. . . seems pretty easy. Looking for any advice/guidance.

If you're talking about the lower radiator hose you will not get an accurate reading

I am. I didn't predict that. Is it off by much

The reading you get from there will be waaay low because it will be reading the temperature AFTER your coolant has gone through the the radiator. How much depends on how well your radiator does its job. The best place for the sensor is in the water outlet at the front of the head.

Probably about 20 degrees low reading.

Tom,
If he put one in the TOP & one in the BOTTOM, he could KNOW if the radiator was doing a good job or not.---LOL
Bill Idiot

Several Parts Houses Sell A Short tube with a fitting for a temp. sending unit that fits in the top radiator hose. I have used them in the past worked great

Go with Vintage Precision great product and has outlet for gauge. Easy to take apart and clean out. ( rust flakes will collect on the inbound side of the thermos.)

Bill's idea is slicker than snot, ideal for the Model A. You could keep tabs on engine temp. and radiator efficiency. Then comes a sensor in the rear of the block to monitor rust corruption at 3&4, before the pistons began to grab the walls.

Since no one else mentioned it it.... Water Outlet

I replaced the gooseneck above the water pump with one that has a boss for a temperature sensor and it works very well. Routed the line through the junction box to the gauge mounted just below the speedometer. Very pleased with the installation.

Yep, thats what I'm changing to this winter, looks much cleaner and with less clamps, meaning less opportunity for leaks.

I did the top water outlet housing with the tapping for the temperature probe. It works impressively well.

Not to highjack this thread but, is that the way the crankcase vent tube is supposed to be routed?

Kill, aftermarket breather tube assy'. No right or wrong way.

I didn't realize that this was an aftermarket accessory type thing. I guess I should have as all of the vendors sell fill tube caps that are just that, a cap with no tube. So if you just have the cap, how does the crankcase vent?.

[denniskliesen]

Through the cap. The tabs inside the cap hold it up off of the top of the tube.
