me again guys,, any posts or instructions on this. Is this very hard??

 

Well it depends on were you put it.I put mine on the down side pipe after the turbo,it works great and was very easy to do. didn't have to worry about anything going in my turbo all was blown out at start. But you EGT'S will be a little lower don't go over 1,0000 degs

 

I can't remember where I found the instructions, but if I could do it, anyone can. Just make sure you get a real good drill bit(s) and take your time. I put it in the exhaust manifold on the drivers side of the engine.

Piece of cake. Your probe should come with instructions on the install. If not, go to Diesel Manor's web site and go to their installation instructions section. They have pretty good instructions. Most people drill and tap into the driver's exhaust manifold just before it turns up to the up pipe. This area is accessible from beneath the truck. I started with a 1/8 inch bit and worked my way up to the final bit size. This keeps the chips very small,almost dust. I then shop vac'd the manifold and also used a pen magnet to fish any "stray" chips out of the manifold. However, my shop vac did a great job as I didn't get any chips on the magnet. Whatever you do, don't use grease on your bits to try to "catch" the chips like some recommend as this prevent the flutes of your bit from performing their function and funneling the chips out of the manifold. It will also prevent the chips from coming out of the manifold when using the shop vac as they will stick with the grease to your manifold.

 

i thought i read somewhere to have the engine running??? is this true?? and if i was to put it somewhere safer,, after the turbo. Is this ok as long as I make the allowance with my readings??? thanks.

 

After the turbo you don't have to have it running.To me it's lot safer and i didn't like the idea of drilling a hole in my manifold,it does weaken it up.And it works great it just a little lower numbers don't go over 1,000 degs and you will be fine.

 

I have 2 EGT probes one in the common location on the drivers side manifold and one right after the turbo. At below 800 deg manfold side the post turbo probe reads about 150 -200 degrees less. At about 1400 the post turbo reads close to 900 degrees on short WOT runs. I think if I were to sustain 1400 deg during a tow the post turbo side might slowly come up and read closer to pre turbo temps. I been meaning to insert the post turbo probe deeper into the down pipe to expose more of it to the exhaust and hopefully get the two reading a little closer.

+2 on PSD2005's recommendation on not to exceed 1000 if you put it post turbo.

 

No need to have the engine running when you drill. IMO you actually run more chance of debris going through the exhaust with the engine running as well as the safety hazard.

Your call as to where to put the probe. However, post turbo measurements have a larger variation and IMO are not as reliable or responsive as pre turbo measurements. Having pre and post turbo probes isn't a bad idea. The pre turbo gives you a reliable measurement of the actual exhaust temps coming out of the engine and will help you from burning down your cylinders while the post turbo can be used to monitor the temps coming out of your turbo so you know when it's safe to shut it down.

 

If I only have a pre turbo EGT probe installed, what is the safe temperature on the pre turbo to shut it down?

 

I let mine idle for a minute after the pre turbo EGT gets below 400 degrees. That's unloaded and not towing heavy. If I was loaded and/or towing heavy, I'd give it 2 or 3 minutes of idle after getting below 400 degrees. Not scientific, just my opinion.

 

I have noticed that when my pre turbo gauge reads exactly 400 the post turbo will read about between 430-450 but drops down after a minute. I have also seen the temp rise back up about 10 degree's after shutting down for a heavy tow for a minute or two before it starts to come back down. I use RP synthetic but what is a safe temp to shutdown?

 

Good info.

 

I've read 300degF is where you should cool down to. Usually my gauge reads around 300-350 when I get to where I'm going. Sometimes I wait until it gets below 300 but most of the time I don't.

I don't see the point in having the only EGT gauge after the turbo. If you have one pre and one after that would be ideal but I want to know what the exhaust temp is before it gets to the turbo.

Here is an image from Dieselmanor.com similar to where I installed mine:

 

They have very good installation instructions too. I should have put a link in my last post.

Not sure if it was mentioned, but make sure you use the correct 1/8" NPT tap (thread pitch) and use grease on the tap......after you have shop vac'd the manifold after drilling but prior to tapping.

I will state the obvious buddy but wear eye protection!
