I know this has been mentioned several times but what would be the disadvatages of putting my Temperature Guage Sending Unit at this location? I see this as a better alternative than to drill and tap the head or alter the upper Radiator hose. Would it not give a true and somewhat close temperature reading? 1948 8N
Thanks, Mark :)

You can put the temperature sender in your upper radiator hose by placing a tee fitting about midway and cutting two short pieces of hose to connect it to the head and radiator. I bought a tee that had a 3/4" pipe thread and a reducer to take it down to the size of the gauge fitting. It was a lot easier than drilling and tapping the head.

All that "T-ing" and connecting sure is costly, bothersome, and has a MUCH greater potential for leaks than drilling and tapping a simple hole, and tapping it with a pipe thread tap!

It worked for me and I didn"t have to risk messing up a 50+year-old cast iron part. I hope LOTS of people are a little hesitant about grabbing a drill and making new holes in antique parts. How many people do you suppose will drill the hole in the wrong place and ruin an $80 head?

If the radiator hose idea did not work, all I would have to buy to fix it is a four dollar piece of rubber hose.

Your idea looks like a good item to make and maybe one kin make a few bucks if he could come up with a clean and neat set up. I have to drill and tap on engines all the time so install’in it in the head izz no problem for me but I kin see were sum would hesitate, its not that bad to do but like enny thing else yes it kin be screwed up.

Thanks for all your responses. I should already know that in the tractor business nothing is ever that easy. I will take pictures tonight of the location on the head that I will be drilling and tapping to get more feedback from you guys. Should wish you lived next door Hobo...

I agree with Bob. This location would be affected by both the cool water coming from the radiator and the proximity to the "relatively" cooler crankcase area. Drilling and tapping the head and block isn't a particularly hard job, especially with the 48 as the generator/alternator is opposite the boss where most use to install them. My temperature gage is located there and reads very close to the thermostat setting when the engine is hot and not under load. Goes up when working. Seems to be very representative of the water leaving the engine. I'd suggest you go for it. If for some reason you wish to return the engine to the factory pristine condition, put in a hex plug, grind it flush with the block and paint it. No one will know unless they NDA the area.

A waste of time and effort. No benefit to that location if it did show a high temp their all it would tell ya izz its to late call the family in my engine izz cooked. I have checked the temp their and when at 200 the lower part of the block izz a round 150 to 160 at the most. @ 160 the lower block temp izz around 130 Also this will scare ya if one checks the temp on the exhaust side of the head at the top you will see temps close to 400 degrees. Put your afford in installing it in the head or top rad hose between the head and thermostat.

If one drills a hole in the head or anywhere else, won't metal pieces end up inside the heads?

Use a small but strong magnet to pull any shavings that fall inside. I will put a magnet inside the gooseneck near the area to drill, hopefully all shavings will stick to the magnet. HTH

I can't give you an exact number, but there would be a considerable temperature difference between the coolest water at the bottom of the block, that has just returned from the radiator, and the HOTTEST water (that you want to be sensing) at the top front of the cylinder head.
