2nd Generation Dodge 24 Valve Powertrain

I know alot of folks have temp fluctuation but I think it usually swings low instead of high. I had this trouble a few months ago and fixed it with a new water pump but its back again. I just had the radiator cleaned and rodded but it hardly had anything in it. Its got another new water pump and I have ran two different radiator caps. I have 3 different t-stats and they all fluctuate the same, two are 190 from napa and one is a cummins 180. I generally see swings from 190-203 or so, usually cruising it stays around 190-194 but will jump up to 197-199 for a second then back down. That doesent bother me as im reading those temps from the ultra-gauge and I think those are fi…

Alright been messing with this for a couple of weeks. Started when it first got cold. Noticed my heat was not as warm as usual. I checked my radiator and it was about half gallon low. After I filled it up I drove it and the heat seemed to be better. When I got home I noticed some antifreeze on the ground. Looked up there and found it dripping from the drain plug. Replaced the plug which I might add is a stupid design and pretty much worthless to actually drain your radiator. Why cant it be a pitcock drain. NOOOO it has to be some nasa frickin design with an O ring that doesn't actually work after you remove it the first time. :banghead: Sorry !! Anyway it wasn't the plug …

My 2001 truck is currently in "temp storage" on my side yard. I've been starting it once a month for last couple years. During the month it sits, the OEM alarm is on and what ever else slowly drains the batteries. Last month I pumped out 2 year old fuel and put in new fuel with a shot of biocide. Thinking I should disconnect batteries or install a battery disconnect. Maybe I could just pull a fuse to stop batteries from draining. If pulling a fuse is good idea which fuse or fuses should I pull? Any other things I might consider?

I had some errands to run today and drove the truck. As normal the temperature came up and held steady at 190*. I stopped at the local station to top off the fuel and left the truck running.It was in the low teens here in Michigan today. I know it's colder in other states but.............By the time I had topped off and went in to pay the temperature had dropped to about 160*Why..........

I am wondering if there is anybody here with an exhaust brake on a 2nd gen with automatic tranny? Do they work good together? There are transmission controls available that lock the torque convertor while braking but do they only lock up in overdrive and drive, or in gears below that? I've been trying to cut through the clutter on everything that's available but not having much luck. Hopefully someone here can help me out. Also what's the best brand to be looking at? Thanks!

Has anyone ever replaced the bearing in the belt tensioner? is this something that can be replaced and if so who has the part number of the bearing? mine is starting to squeak and i figured that this would be the cheaper route rather than replacing the entire tensioner. thank you.

My tensioner started sqealing like a pig. I plan to replace it but was wondering what the torque is on the bolt and if it had been over-torqued, could that make it squeal? Thanks

Beginner question... adding to my birthday wish list. Terminal tools for wiring. What would you recommend.

Is Quadzilla a "live data tool" or is the "live data tool" a section within the Quadzilla? ( I know beginners = real pain in rear) (edit part...adding onto post) I need a code reader and unsure what to get and at same I would like a little more power. I've been reading this thread https://mopar1973man.com/topic/11729-quadzilla-adrenaline-v2-testing/?tab=comments#comment-140263 and it seems it would work for me. But terminology and knowledge totally lacking on my part. Thanks

I really just want to see if it is just me or if others have the same luck. 3 years ago i smoked an airdog 150. Bad seal between motor and pump burned it up. 8 months thirteen days on that one. Replaced with a raptor 100. 123 days later, bad seal, smoked motor. Replaced with a raptor 150, Big lines from DSV to VP. A year and change later. Dead. Opened it up and I'm telling you, no magnets left. Just a big pile of soot and carbon inside. Replaced with a warrantied 150. Eight months to the day, same thing. Dead. Only this time, brushes as well. I rigged up a stocker with some fittings and hooked it to the biglines of the Raptors, plugged it into the raptor harness and …

Man, I tell ya, something is gong awry. I done alot to get my truck into excellent running condition. The truck practically is "brand new". The list is long with what I have done to the truck. The most extreme of things I have not yet done are replacing the vp44, tps, turbo, etc.Over the course of a few monhs, my mileage has dropped significantly. I was averaging about 18-20 mpg right after I replaced my injectors. But now, my mileage has dipped down to as low as 14mpg on avg!I don't understand what this could be stemming from? I have not noticed any drastic change in performance in the truck and have not had a CEL. Granted, I can scan for codes tomorrow and check just to…

If I tested my alternator correctly... touching the positive probe of my multimeter to the big black wire on back of alternator and negative probe to the negative post of the battery.. with my multimeter set to 2000mV... I'm getting a reading of 1. Does not fluctuate or anything. Is this okay or am I doing it wrong?

Hi, i'm new to this site and there is a-lot of neat stuff on here.I got a question that maybe someone can help me out with.I got a 24v engine out of a 2001 school bus been sitting for a long time so i threw it on my motor stand and put a new head on it. I want to test it on the stand but having trouble wiring the apps because it is on the throttle pedal and not on the side of the pump. I don't want to burn the pump up by doing something stupid for it is a new one.I have already had it running but only at idle i want to throttle it up but can't figure it out . Thanks Craig

2001 24v. Blue Chip V44, Fass DDRP lift pump, Beans sump with 1/2" hoses, otherwise stock. Autocomputers repaired my ECM and PCM ECM- Replaced Lift Pump circuit, Resoldered CPU, Resoldered Flash Chip, Replaced APP circuit, Replaced 9.5 and 5v drivers. PCM- Replaced voltage regulator, replaced 3 220uf caps, resoldered CPU and Noise Filter. I have replaced the alternator and installed a 5A fuse to protect the PCM. I am testing the wire harness for shorts and haven't found any. If I do the W-T mod first, will it be safe to connect everything and turn the ignition on so I can connect my new BlueDriver and check for fault…

I want to personlly thank Dually and Michael for the help and pictures ,when I replied about the APPS installation, got it today installed and took it for a test ride and noticed the differance,quess the old sensor was on its way out,,,, again Thanks

I needed to put the 7x12's on the shelf.I wanted to see if i could get better mpg.As well as help my new vp last a little longer.I traded some guy.He wanted my old hx40.I wanted his rv injectors.So he gave me some cash and the injectors,i gave hin the 40.I sent the injectors just to get freshened up.The guy at the injector shop told me they were crusty.He fixed them up and did whatever them guys do and sent them back. So i put them in.I had hard cold starting problems.Somehow air was getting into the system.I did find the return line needed to be tightened.Did that little to no change.Then i remember the injector guy saying something about (They should work themselves in)…

Just wanted to take a minute to say thank you to everybody in this forum for all the help you give me and each other. This place really is like no other when it comes to getting help or advice with Cummins issues. I don't post on here much because I don't know enough to help with most of these issues but I do read A LOT and there is always a wealth of knowledge and ALWAYS someone willing to help. This forum has taken me from doing oil changes and an occasional brake job to finishing my first VP install about an hour ago. Mike I especially want to thank you for creating this place and deciding to keep it going. I'm not in a place where I can donate monthly right now but I …

Well the past couple of days my pressure started out at 13 then it went upto its usual 17. Once driving it, it would drop 4 or 5 psi! :wow:I change my fuel filter at every oil change, it was time to do it. Put the new filter in and it is right back to the steady 17 psi. Now I see how people kill their VP when the lift pump goes out and they don't have a pressure gauge!

Thanks to all that share their knowledge. I just did the valve lash adjustment. Only took 4 hours. Not to bad for first time. Thank you Mopar1973man for your GREAT article with pix. Now onto my next project swap out the injectors for some RV 275. Couple more paydays then back here to get the info needed to do the job. The change in the sound at idle was amazing. Seat of the pants I would say 25-30% better running, seemed to get up to speed faster, will have to be careful already spun tires. Most of the valves were loose. intakes were .012-.013, exhaust .022-.023. I guess not to far out for 217778 miles.THANKS AGAIN!!!!!!!!!!!
