Location of your egt thermocouple

[Albie30]

I was wondering where eveyone had their thermocouple for the egt gauge I ve got mine in the drivers side exhaust manifold Right where edge says to pit it but I think that could leadto problems only reading temps from one side of the motor Would it be better to put it in the down pipe???

no yur in the right place leave it there

I think you have it in the right spot.there will be some one that has more info on this then me.

Unless you're a competition diesel then one place is fine - most all cylinders will be very close in temperature. I've heard of people putting a probe at each cylinder but that's on a pulling truck...

EGT probe placement

heres a guide

Thanks How is that pre turbo ???

good to me , max i get is about 1350 but thats pushin it


pre is the way to go

I've got mine in the up pipe (dunno what ya call it) that connects to the driver side manifold. Didn't wanna pull the manifold and felt kinda sketchy at drilling the manifold on the truck. So when I did my 5" I pulled the pipe, drilled it, cleaned all shavings out real good, mounted the clamp on style thermocouple, and called it a day! Should be as accurate if not real, real close to having it in the manifold itself, I think .

Mine is in the drivers manifold. Everything I have heard says that a probe in the down pipe doesn't react fast enough, and shows a lower temp than at the manifold, so you have to do some figgerin to match up if you know what I mean

Yeah in the manifold its reading is coming right off the engine before the exhaust gets to the turbo where as in the downpipe it has had time to cool and I have heard could be 300 degrees cooler. Im sure there is some cooling going on before it hits your turbo from the exhaust manifold reading but at least you know by the time it hits the turbo you won't be maxed out.
