Engine/Transmission (1998.5 - 2002) Fast reacting exhaust probe

[59Turbo]

I'm looking for a fast reacting exhaust thermocouple. The one I have now is way too slow and I fear I'll melt something before I even see it on the pyrometer. What's everyone using? I can't remember which one I'm using off the top of my head cuz it's mot the one that came with my Autometer gauges. thanks in advance, Dan

"I'm looking for a fast reacting exhaust thermocouple. The one I have now is way too slow and I fear I'll melt something before I even see it on the pyrometer" ???



is your pyro downstream of your turbo?

Sorry, it's upstream and tapped with 1/4" pipe thread into the manifold.

You might try getting a replacement from Autometer. The one that I got from them reads as soon as I step on or off the gas pedal. Or maybe the gauge is sticking? How old is it?

i got a vdo thats slow too and it sits right between cyl 1 and 2 on the left side its the truck in sig

My Dipricol moves up as fast as the tach. Going down is slightly slower - but that's not the probe's fault. :-laf

My Autometer seems to be very fast. It moves quicker than the speedo, which I find annoying and plan to remedy someday...

Isopro with the amp boxes is real fast,

go with a thinner sheath diameter. I run an ungrounded 1/16" inconnel 600 thermocouple that is very responsive. less mass is good :-laf

I 2nd that... ... ...

Just about everything you need to know regarding thermocouples used to measure exhaust gas temperatures in this article from issue 34 of the Turbo Diesel Register: https://www.turbodieselregister.com/EGT_EVAL.pdf

Thanks for the replies guys. Thomas, thanks for the link, it's just what I was looking for.

Talk about fast here is autometer's 5243 probe on the right. Probes that come with a reg. gauge are not that quick to react. Like (Bob said the thinner the faster) but this probe here cost more than a EGT gauge kit. About 165. ?? just for the probe and the open end just has a wire.

Holy cow ^^^thats sweet.

I didn't know about those. Gonna have to go get one now :-laf
