2nd Generation Dodge 24 Valve Powertrain

Do the cummins brand of t stats have a fail safe?The question is when they go bad are they made to brake in the open position? My engine gets hot 190.The t stat housing is hot. The radiator fluid is cold.I am thinking water pump. The radiator and heater core were flushed in summer.

Took my truck and trailer (trailer rated for 14000kg) and drove 3.5 hours to pick up a backhoe attachment, drove back. Filled up and checked my mileage and was very dissapointed to see the result! 11.6 mpg

Now that it is getting colder outside I'm preparing to change oil in my truck. I live in Illinois just East of St. Louis. Occasionally the temps will fall below 10*F which is out of the 15w-40 range according to the chart. I'm curious what some of you guys do regarding oil changes and viscosity? Do you change oil in the fall to 10w-30 and then again in the spring back to 15w-40? I know I can buy 5w-40 but all I've seen is a full synthetic. I only put about 6k on my personal truck in a year, so when I had my gasser I would change oil at the 3k mark. I've only got about 2500 miles on this truck since the last oil change. I hate to change oil unnecessarily but again…

My exhaust manifold has a small crack....doubt there is any way to repair this besides replacement.Anyone have suggetions on what aftermarket manifold to buy? not sure what mods I will end up doing to this truck down the road....nothing to extreme though. Just want somthing that will help it breathe better,won't crack and won't brake the bank

Just took my truck to the voltex battery today and had new batteries installed, I figured its about time the old ones were 6 years old and weak. They put it 2 of the 65 group size blems (2nds) for $35.00 each, left there with $75.00 out the door with a 1 year warranty . I work at advance auto parts, part time and they are $90.00 each with my discount. If anyone has a battery store that sell blems that will save you a lot of money.

Well if Cummins cant fix it it's doomed to fall of a clif. I took truck to cummins to let them try. Well if I had stock injectors he said they could search for leaks by pressure the system. And there stock injectors are about 500.00 each, thats what he said,I dont know. They did the usual routine stuff, hook up scanner and the usual stuff came up NOTHING. They seemed sure that the crossover tubes where leaking and one may have been. It runs a little diff. but miss is still there. Here is where I am at,new DDP 50 HP injectors, ECM,Apps,crossover tubes, cam sensor, VP Blue Chip, Head rebuilt, Starter, Alternator, water pump, thermostat & sensor, new airdog 150 with quic…

Upgrading your diesel. In order to upgrade your diesel from stock, you should have a baseline of readings in order to know what has changed. Also, if you do multiple upgrades at one time and something goes wrong, you will not know which upgrade caused the problem or error code. In order to know what is happening to the engine, you should have at the minimum compliment of aftermarket gauges. At the minimum for Dodges, you need a fuel pressure gauge, boost gauge, and EGT gauge. Those with automatic transmissions should also have a transmission temperature gauge. With these gauges and a stock engine you will proceed to gather information as to how well the engine…

Ok guess I am just stupid. Repacing my radiator and got it out without having to remove the fan clutch.But tried and couldn't budge it. Searched this site and other places on how to remove it. Some places say there are holes in pulley mine does not. Tried using a rubber belt ratchet thing to hold pulley. Didn't work. Found this pic of tools to use but not sure what that 71 mm wrench holds. The 36 goes on nut holding fan clutch but where does 71 mm wrench go to ????Thanks Rob

So yesterday I was driving in winter like conditions, busted through two snow drifts, shortly after that my dash went dead except the tach. 'No bus' was displayed in the odometer and my over head consol had 'CCd'. I was able to get to a small town only about 70 miles from home before the batteries gave out. I just put on an ecm and pcm from a 99 manual, so I am not sure if the ecm gave out or if it might be an electrical issue? I tried to read the codes with my Smarty but it seems that it can not find the ecm, it just keeps telling me to turn the key off then turn the key on. I do have a down load on the Smarty so I am also wondering if the ecm is toast is there any …

Is it pretty common for these trucks to not come equipped with overdrive?

My lights are on and it pulses like a bad rotor.Can anyone tell me what to check.I had all this problem before i replaced the wheelbearings,rotors and ball-u-joints.When i am light on them around 30mph it seems ok, hit them hard the pedal pulses.I only have a smarty to check codes so i cant get into the abs computer.

I bought this truck a couple of weeks ago with the owner telling me that he thought it needed a new VP44. The one in it was rebuilt just over a year ago. I've been working on some of its other problems and trying to figure out if it is in fact the injection pump that is causing the trucks problems. Basically the truck will sometimes start missing and farting. Sometimes it is just a minor little blip and sometimes it is bad enough that it will die at idle. It happens at all RPM ranges but is definetly worse when there is no throttle applied. Some days it does this right off the bat and other you can drive for 30 miles without any problems. When I got the truck it had codes…

I know my VP44 is on the way out, but I was wondering if installing an airdogII now would hurt anything. I think I'll go with the AirdogII because I like the idea of the adjustable regulator. Does FASS offer anything that's adjustable? I'm still hoping the vp44 makes it to spring.

I saw this but opted for Ubuntu instead of Vista on my laptop. Am in the OS learning curve. http://www.obd-2.com/#download There is lots of linux related conversation also. Just wondering what others here have done. This looks interesting also. http://www.scantool.net/software/scanxl-std.html

I'm stock except for the exhaust. I don't tow very much... but when I do, we put 600 miles on in a day. I don't know how heavy the 28' Tahoe TranSport is but I found one year listed as 7000 dry weight / GVW of near 10,000 (a second listed GVW of 12,000). Truck (see signature) has Tow Package which includes a transmission cooler. I haven't been able to add guages yet. Note: I've discovered 4.10 is the wrong gear ratio with stock tire sizes but I own the truck now. As I posted previously, I pretty much have to use OD on flat & downhill, kick the OD out & drop speed if the truck is unhappy on a grade (no issues except loss of cruising speed). I'd like to bum…

what do uguys recommend for fuel additives?I see some of you use 2 cycle for its lubricating value but what about for the cold winter months to prevent gelling......all of them pretty much the same?I think they use a product called 911 at my work.Oh....and what do u think of stanadyne additives?

There was a write up on it and cant fine it to save my life. Anyone know size and pitch? Need to clean block --- Update to the previous post... I got it, cummins ordered me one, 31.00

Hey guys - replaced my injectors 1x with ISX holding my hand (where's the "flower" icon ) anyway Thinking of getting rid of my RV275's and going to +75 => +100HP ...... together with hx35/hx40 hybrid. That with my methanol/water kit should bring right at 275->425 HP which is as far I as think I should go without new headstuds/bigger turbo. So thinking a couple things. (1) What you think between full injector replacement or just nozzles ?? (2) Think of these http://www.cumminsperformanceparts.com/cpp-injectors.html + 100HP and http://www.dieselautopower.com/product_p/35-fslash-40%20turbo%20budget.htm or something else in some price point ? I haven';t …

I know this is a dead horse but i need input from anyone that has experience. My current setup is HX35/ht3b, Edge juice (HOT) WAM, JL Machining 240hp injectors, Haisley head gasket with fire rings, ARP studs, 6 spd, SBC 3600 DD , 3.54 ratio. I think I have enough supporting mods for everything I have but I know the JL's are way to big for towing. I can easily stab 1500 in the back in about 3 seconds when I get on the juice. I have towed with this setup some but really have to be on top of it. I been there and done that and now I just want "usability" so I am fixin to order some new injectors from Jacob(diesel auto power) he seems to have some good prices. I have decide…
