I have a D max 2004.5 lly and I thinking about install a egt guage. I know that some people install these on the passenger side exhaust manifold. I have seen the instructions and the pictures, however I am thinkling of installing the probe on the exhaust pipe on the passenger side with a stainless steel hose clamp provided by ensproo guages. This way if the probe should drop off it will not damage anything. Has anyone completed an installation like this and is this the right way to go about it or does it make any difference. I am also going to install another water temp guage on the side of the block in one of the drain plugs. Has anyone done this yet and is how did you do it? Thanks for the help. Love my D Max-:t

Dosen' anyone have a thought or answer for my problem

personally I think the manifold is the best location just because you will get a more accurate reading. if you install it further down the line in the exhaust the temps will be different and maybe not what you are expecting or should be. I would think the temp coming right out of the manifold to be the hottest and is what you want to monitor since that then goes to the turbo.
that is how I picture it in my head, but I could be wrong.
just my $.02
Good luck

I'm with Briano, if you want the most accurate reading, install it in the manifold like it shows. That's what I did, and I think for the most part everyone has done, and it seems to be working the best.
An EGT probe installed after the turbo is of no real value since the primary reason for monitoring EGT's is so you don't cook the turbo and shortly there after, the rest of the engine. The reaction time and the differences between pre and post installs are such that there is no reliable scale to figure out what the pre-turbo temps would be on each specific vehicle. Some here have installed EGT's post-turbo for various reasons, but even most of those folks have one installed pre-turbo as well.
The worry about a probe breaking off is something that's not likely to be a problem with the materials and manufacturing methods used these days. The gauge should stop working long before the probe was eroded enough to break off.

Most definitely needs to be in the manifold to be of any use.

Does the turbo get it's air supply from the exhaust manifold, the air intake or both? I'm confused! If it does get it from the manifold how does the turbo keep from getting all sooted up?? And if it is getting it from the manifold, isn't this the same principle as an EGT? If it's not getting it from the manifold, why is it so important to monitor EGT temps pre-turbo (manifold)?

turbo gets both air and exhaust, but not in the same chambers.. the exhaust side only turns the shaft that is connected to the turbines on the turbo (if this is too hot it will melt the impellers).. the air intake is on the turbo side and sucks in the air and compresses it as the turbines are spinning forcing it into the engine.
reason you take the EGT's on the manifold is because the exhaust and temp coming out of there feeds teh turbo and if that gets too hot you fry your turbo and just like someone said above..shortly after that you fry your motor.
there is a better explanation for it than what I have mumbled..but that is my lamens terms.. lol

Thanks! That makes more sense now.....the air used for combustion comes from the outside - the air used for turning the impellers comes from the exhaust manifold. They must get sooted-up to a certain extent then. Why not turn the impellers with electric power?? Not enough supply I suppose!? Of course, who needs more electronics ):h

Exhaust is a "free" source of energy to turn the impeller. That's the beauty of a turbo...taking wasted energy and turning it into horsepower! :ro)

Thanks for the info I will install in the manifold as been discussed. Ive seen pictures of on various threads and have read thier instructions.
