Thermocouple installation....

[HVAC SuperTech]

ok, I just got my Stewart Warner Guages and A pillar pod in, when you install the thermocouple, where should be installed? The tech section said on the up pipe of the drivers side exhaust, but, the gauge instructions say mount it after the turbo. Where do I want it installed? Where is it going to be giving me readings that I can count on for good engine information?

Drivers side manifold for the best readings the downpipe can read almost 400 degrees cooler

i am also to the same point as you. I have the gauges and i'm gonna install them soon. Everyones opinion on here was the same. Mount it on the drivers side up pipe BEFORE the turbo. Check out dieselmanor.com and there is a whole write up on putting the thermocouple in, pics included. Let me know how it goes for ya!

Your exhaust manifold for the most accurate readings. If you install after the turbo on the downpipe it has had too much time to cool and won't let you know what the actual temps coming out of your engine. Here is a pic for the 7.3

ok, thanks!!

Was wondering about the shavings. It says to vacume out the hole. To vacume out the hole, you just use a shop vac or whatever right? nothin special bout that? Will that get the rest that dont fall downward, so they dont enter the turbo?

[vitalidle]

Yeah a shop vac should get you fixed up. What if any shavings you get in the manifold are small enough not to really worry about anyway as its going to pass right out the exhaust.

K, thanks Vitalidle. Lots of help!

My gauge is on the backside of the turbo, how far off is it going to be?

another tip for drilling the manifold is along with vacuuming it out, go buy a small telescoping magnet and probe the hole several times with it prior to installing the probe... I got one at the local farm and fleet store for about $4. Cheap extra insurance.

Back side of the turbo would be in your down pipe. Its going to read really low, maybe between 300-500* lower than the actual temp coming out of the exhaust manifold. Manifold temp should never exceed 1250* or so for more than a few seconds (like 10-15 sec.) If you have a post turbo probe I'd be nervous if I saw 750*'ish or more.
