EGT install

[Randomrunner12]

Hey all,

Wanted some advice from some more experienced folks around here. I am getting ready to install some new gauges in my 2012 ram g56 truck that has long been deleted, studded and has an S465 swap.

I sold my edge insight a while ago and due to family issues have finally gotten around to getting my auto meter z series boost and egt. My question to yall is......

Should the truck be cold or could it be hot such as after having driven it before i remove the 1/8" NPT plug from the manifold and install the new EGT probe and all the fun stuffs? I know that cold i wont burn myself but I have gloves to prevent that.

You could probably do it both ways! But why chance on burning yourself, I would let the truck cool and then install the EGT probe and what ever other monitoring probes you are installing.

I would do it cold, unless in the rust belt, in which case, the engine heat maybe appreciated on a day like today.

It might be easier to remove the plug when hot, then install the new one after it cools off. But I'm with Jim, it probably doesn't matter.

IMHO technically it might be easier, i.e. less damage to threads, when cold. Steel or brass bushing expands more than cast iron, thus tighter when hot. To hedge your bet, drip some penetrant at threads when still 'warm', i.e. not hot enough to boil off the penetrant.

I did this to rethread my 2004 probe's 1/4MPT bushing to keep debris out of manifold...a slight mod to my shop vac nozzle.

Thanks Walter J and everyone else that replied.

Got everything installed back February and did the job one weekend after lunch at my old man's. That way the truck had time to cool off.

Got my auto meter z series boost and egt installed and setup and working great.

My next question, should I cut the slack on the 6' air line I have for the boost gauge or just leave it. It seems that an electronic gauge is more accurate than the mechanical and I'm wondering if that's because of the length of air line?

In my experience "line loss" is insignificant when deadheaded to a gauge only 6' away, 'cause the actual flow is miniscule, but has no effect on accuracy, only affects response time, which would contribute to some needed damping afterall. [that's the tech in me coming out...]
