When you run out of room for gages?

This ties into my post in finishing up the water pump and repairs I just completed. I wanted to add an aftermarket coolant temperature gage (Bosch) and an aftermarket coolant pressure gage (glow shift max tow)

I measured the lower dash and had just barely enough room for a two gage pod, but it was made to mount upright on top of a dash.

Below:The three existing holes (red arrows were for mounting upright. Then I took a dremel, removed some plastic and JB welded steel clips for mounting it

Then painted it grey, not an exact match but closest I could find to my dash.

Below: I had wired a longer brake controller pigtail onto the truck. I kept the supplied “illumination wire” originally with the brake controller for my two gages and moved the brake controller behind the access plate with the bag hook.

Below: Some of the wires had to be hooked up to the coolant pressure gage first, and then the gages attached to the pod. Then the excess wires were taped up and inserted back into the dash

Below: The max tow gage was already green with several brightness adjustments for daytime and nigh-time and selection is kept alive by constant 12V power. The Bosch gage used a 363 clear lamp. I found an Ebay seller who sold green 363’s for model trains. The green backlighting was perfect.

The gages are working great, and the coolant pressure gage is climbing as I drive, now at least I’ll have a heads up when there are coolant leaks or I have a cap on the degas bottle go bad

Nice work,
what is in the tray just above the new gauges?

I presume you want the Coolant Pressure to detect the DeGas bottle cap is cracked?
being a newbie to the 7.3L, how does that effect the engine when the pressure gets too low, or at Zero with a bad cap?
That space above the gages was just a pocket for coins, miscellaneous.... and I saw on RT’s post where he had put his ScanGauge2 there using a spacer block of wood to make it flush. I was really impressed, and RT sent me a description of what to make. The ScanGauge2 does a lot of stuff and shows 4 items of live data at a time which you select from a list.
(post edit: corrected text to read 4 items of live data shown)

As far as coolant pressure dropping I never noticed the engine running any different and it never overheated but when I changed the water pump there was signs of cavitation erosion. I have know idea when it happened, but when checking my cap it wasn’t holding pressure, so I wanted something in the future to keep an eye on the system pressure and an aftermarket temp gage as the dash instrument is just a sweeping needle of cold to Hot. I had a temp sensor on my water pump go bad and my oil temp on my ScanGauge2 was good but now I’ll have the actual coolant temp gage to fall back to for reference.

I’m also going to take one of my used, spare degas bottles, cap the hose fittings and add a Schrader valve making a test bottle for checking caps.

Kevin, Nick and the other guys knew what the cavitation erosion was on the front cover👍......... I’ve never ran into that before.

I just recently bought a holder for my iPhone that’s attached to the vent and love it.
John, my Max Tow gauge is still a little too bright on the daylight (d1) setting due to LED backlighting. I called Glowshift and talked to the techs about twisting my white (12v key on) and orange wire (headlights) together along with the key on 12V+ supply from fuse box to fool the gage and always default to night-time mode, both day and night, Tech’s said “yep - no problem”

Picture taken during Daytime - d1 lowest setting: a little too bright though it doesn’t look as bad in the photo

Picture taken in Daytime - parking lights on and n1 lowest night setting which is what I will re-wire to default to all the time, and the Bosch gage backlighting with the Green 363 bulb:

Yesterday, I took the truck up town and washed it. I think coolant system was 8psi which I’m reading is a really good pressure (7-10) for normal driving, no heavy loads, no towing, etc. Anyway had truck turned off for 20 minutes or so to wash, fired it back up and was still holding the same psi with no loss.
Kevin, Nick, bugman, and everyone else that contributed to my post prompted me to do a lot of reading on cooling systems, pressures, water pumps, cavitation, etc. something I was severely lacking knowledge on.... really quite interesting👍

I have purchased the GlowShift Fuel Pressure gauge,
that is one of the items that needs to be installed muy pronto.

I really like my fuel psi gage, another kudos to RT for his many posts and his thoughts on the fuel gage’s importance.

right now, the back of the truck is up in the air, my son is installing the Fuel Sump kit for me.
I am too slow and clumsy now it seems, I thought I would help out a bit yesterday, and ended up a mess

It happens. I’ve got hide like a rhino but now with blood thinners I bang up pretty easy. I’d say your doing pretty good— if I remember you’ve got a few years or so on me 😉
