With the problems I've been having, I think your assessment should be correct. Actually, it sounds like a great protocol to begin. Maybe it would help me justify my work and decisions. Ha ha (I hope)

layback40: I'm glad you've been inspired with my efforts. I'm glad to share them.

Everyone else: Can't find the 'tune to delete the Glow Plug part of the ECM programming. I've seen it here someplace but so far I haven't had any luck finding it again. Anyone know where it is?

I checked my glow plug wiring and it all seems sound. Next I'll have to check voltages coming to the Glowplug Control Unit (GCU). Last weekend I had to rebuild a door in our bathroom. darn Termites! This next weekend is coming soon...

Searched real good using all search functions, even did a Global Search with no hits either.
Search Tool:
LOSTJeeps Site tool:> "put-search-text-here between quote marks" site:www.lostjeeps.com/forum/

Reach out to Marco (Yeti), bet he could help you with this.
He can also be Messaged over on FaceBook, search for "Yeti Chip Tuning"

Thanks WWDiesel,

I sent Yeti a message through Facebook IM and he asked for the Glow Plug Control Module number. I replied with the number from the Bosch GCM 0 281 003 034. Also sent my Engine Control Unit number.

It's Friday night already so I don't know if he operates after hours.

Yeti wants a copy of my ECU software so he can determine how to delete the Glow Plug software. Attempted to download the ECU software to the laptop via MPPS program but it did not work. It could not find the ECU. So, plan B is to simply fix the glow plug system on the Jeep.

The main DTCs for the Glowplug Control Unit (GCU) was low voltage on 3 of 4 glow plug wires. I found 3.5v on the Glow Plug Control Unit pin 11, where there should be 12v. The likely suspect is splice S123 in the starting circuitry. So, instead of digging into the wire harness (which is behind and under the power brakes vacuum unit) I ran a new wire to pin 11.

Image

I'll find out if the Jeep goes into Limp-in mode again over the weekend or during the week. The low voltage DTCs are gone now, but still have a GCU Malfunction code P0670.

When someone else needs to find the pin numbers for the Glow Plug control module, here they are. I PhotoShop'd the numbers on the pictures to match the Field Service wiring diagram numbers.

The business end of the wiring harness to the Glow Plug module.

The backside of the harness connector to the Glow Plug module.

The pins on the Glow Plug module.

I still want delete the Glow Plug software and the EGR system.

The beast went into Limp-in mode after idling for about 15 minutes. Got diagnostic code P0299: Turbo under pressure, Turbo pressure sensor malfunction, Low oil pressure. Erased the codes and P0299 went away, along with Limp-in mode.

I'm starting to think that some damage occurred when my PCV hose kinked and pushed my oil out of the front seal. So, for now I'll simply avoid idling very long.

Wow, it's been a month already. Been chasing a problem about the beast going into Limp-in mode and tried a couple things...
    Checked boost hoses for leaks. all good.
    Checked vacuum reservoir solenoid. it's good
    Connected the electric radiator fan up again. maybe made a difference but didn't cure the Limp-in mode.
    Checked mechanical fan clutch. not in such good shape. :(

I've never liked fan clutches and never understood what good they do. 50 years ago I changed a Datsun clutch fan to a mechanical fan and drove away happy. :D Now I've done it with this Jeep and I'll see what happens.

Drilled 4 pilot holes through the 4 clutch fan mounting bolt holes and avoided damaging the threads. :) The drill went through the clutch assembly and the clutch disk.
Image

Flipped the clutch assembly over and drilled 4 clearance holes for longer bolts to go through the clutch housing and the clutch disk. Ran a tap through the holes just to clean them up.
Image

Got some longer bolts (5/16-18x1" NC) and ran them in through the clutch housing and the clutch disk.
Image

Reinstalled the fan onto the fan clutch assembly which is now a pure mechanical fan. All seems fine so far. :)
Image
If this doesn't fix it, then I will have to check the turbocharger waste gate. It could be leaking...

Ordered a $58 Viscous Heater delete kit from IDParts. I didn't notice at first that it also deletes the mechanical fan. :oops:
Image
Sent them a message to see if they can provide a serpentine belt that bypasses the Viscous Heater but still runs the mechanical fan. I don't like the idea of relying on an electric fan to cool the engine.

Dean.

Ditch the metal fan blade and upgrade to the GM 11 blade lighter plastic fan and the larger heavy duty V8 fan clutch. Moves a ton more air flow through the radiator stack. See picture 1
As to the viscous heater, I can provide you with a delete kit that gets rid of the viscous heater but still allows you to use your stock serpentine belt and keep your mechanical fan. See picture 2

Thanks WWDiesel,

I know about your offer of Viscous Fan idler pulley replacement. My choice is to remove the viscous fan and gain space and accessibility around the front of the engine. Thanks for the offer and reminder. :)

Regarding the fan, I may change to a Nylon(?) LDPE(?) plastic fan later if my problem persists. That is something I had not thought of before. Thanks.

At the moment, I'm taking a week off work to relax before going back for my last 6-month run to retirement.

Dean.

Biggest problem with plastic fan is if you drive through deep water, it can bend into the radiator.
Take it easy for the next 6 months! Congratulations!

layback40,

Not much chance of me driving through deep water since there are no surface streams nor lakes or ponds on the west side of the Big Island. Only chance is to drive into the ocean.

Thanks for the support of approaching retirement.

Dean.

Drove the Jeep today and there is an immense difference in fan sound. Nothing off balance, but the rush of air sound is very noticeable. Maybe that is the biggest advantage of having a clutch is to have the fan sound reduced.

Dean.

The sound is all the extra air.
I did the same thing about 20 years ago to my old Mercedes 300D.
It worked very well. Only problem is that it puts a bigger load on your belt.
My fan belt failed after about 10,000 miles.
Its a bit like why the alt has an overrun clutch in the pully of the CRD.
You may wish to keep a spare belt & tools in the car just in case.

Thanks layback40,

When I get the new Viscous Delete Kit I'll get two new belts just to be prepared.

I ordered a Viscous Heater & Mechanical Fan Delete Kit by mistake. Returning it to IDParts means losing 10% plus paying shipping back to them. Doesn't seem worthwhile, so if anyone wants it, contact me via PM to arrange shipping to you. Mail a USPS cushioned bubble envelope to me with postage already on the envelope.

Now I'm searching for the right parts to delete only the Viscous Heater but keep the mechanical fan. Measured the length of the serpentine belt and found it needs a belt about 12" shorter. NAPA says the original CRD belt is 113", so that calls for a 101" belt. I bought a 101" belt and a 100" belt.

Next part to find is the idler pulley #1 in the image.
Image

I've been searching but so far have not found the right pulley. Anyone have some suggestions?
70mm diameter, 17mm bore, 26mm width, 5-grove pulley.

Dean.

Closes pulley matches to your quest I have on file.
Pulley
Manu. Material PN OD Dia. Width Bore Flanged Y/N
Gates Thermoplastic 38009 76mm 25mm 17mm Y 6 grooves
Gates Steel 36157 87mm 31mm 17mm Y 6 grooves

Dean, I still have a big problem with the design you posted due to the huge loss of belt contact surface to the both the AC pulley and especially the crankshaft pulley. Not to mention the loss of the cooling fan.
I think this is going to cause a several belt slippage problems under load.

That is why I designed and sale the viscous heater delete kit which retains the OEM belt length and all belt contact to pulleys remain the same.
You simply completely remove the viscous heater and replace it with an in-kind size idler pulley and bracket (see picture) and this allows you to keep your mechanical fan in service if you want, or to completely remove it, you simply screw the fan and fan clutch off the hub pulley. :D :2cents:
