Thread: Temp Sender?

Tweet

Just for s's & g's, how about a little "shade tree logic"? The key word(s) is water temp. Now, I ain't an egineeer like some of y'all, but it seems to me that the best indicator of overall, average engine temp would be to take the water temp at the spot in the engine where it is the average hottest, just ahead of the thermostat where the returning water all comes together before heading to the radiator; between two exhaust valves in the head, even though it is in water, will give you the temp at that point only. I know, y'all prolly already had that figured without sayin' it, but I just thought I'd poke it out there anyhow. I'll duck and cover now and put on my thick skin so's you can throw things at me and call me names.

And, Mike, thanks for the lead on the symbols; that's gonna keep me busy for a spell.

Roland, someone in the past showed it to me the same as I passed it on to you, I simply taught you something that you didn't know, like the º instead of using 'degrees'. The question shouldn't be WHY?, it should be WHY NOT? Do you remember sitting in a class at school thinking, "I'll never use this later", well ALT 0254 might have been the same................until last night!

Have fun but don't burn the retinas

Doesn't work on my Windows Vista either. Maybe there's some special way of entering it?

Good thread, we get customers all the time wondering why the temp is different at different spots on the engine.
I get many folks calling with their infrared heat guns pointing at their radiator saying thet their gauge is wrong. Please don't use a temp gun to check the temperature of the coolant inside the engine from the outside of the block, or radiator!

@ntfday well sir the general has always put the temp. sender in the head for the gauges. the one in the intake is for fans or computer. I just thought that GM may know more than Me or you do about this. I do believe the head would give a more accurate reading of the engine.

All i'am saying is this is how General Motors does it and Me myself being a line mechanic for 30 years I want to know what the most extreme wtr. temp. is so i dont blow head gasket or crack a head. Put it where ever you want LOL thats just where G.M. puts theres.

I guess in those 30 years you never had the chance or opportunity to work on an early sbc, say circa 57, since the heads had no provision for a temp sending unit. There are others on this board who probably remember it better than an I since I was only 13 at the time.

Yes i would say other things can cause heads to crack and gaskets to blow, but from my experience I would say nine out of ten was due to over heating. sense the engine has over heated, i would say nine out of ten it is because of low coolant level. the problem of cracked heads was more likely in 80's and newer small blocks due to thinner decks on the heads. I would say 230 degrees and up will cause these problems. which is why i would put it in the the head for a more accurate reading of engine temps. again put yours where you want me and G.M. will put ours in the head. lol You are correct ntfday not much work done on 57 LOL besides all 57s i see nowadays have blown big blocks install or fuel injected small blocks. lol Sorry if i made anyone mad with my thoughts on this matter. I was just saying
