    Did a search and couldn't find exactly what I am experiencing. Sorry if this is in the wrong spot or has been asked a million times. Was having a coolant temp issue so changed sensor and thermostat. Now My coolant temp is reading all over the place constantly. Always bouncing around. It shows...

    About to head to AK. Coolant needs a top off. can’t find the recommended Mopar. From what I’ve been reading is you can use Zerex g05. So my question is can i use Zerex G05 in my 2014 6.7 even though the manual says OAT and Zerex G05 is HOAT? I was told to stay away from the Zerex Dec cool...

    So i have replaced water pump, fan clutch, radiator, thermostat but anytime i give it some throttle she gets up to 210-220 and won’t cool down. i can’t seem to figure out this issue and i had also did a whole system flush with coolant, still nothing.

    I have a 2001 mostly stock 24v only 172k miles. I was just recently experiencing a wastegate that was stuck closed that's what I thought. It ended up being the Pitcock air goes through to get wastegate. So it was building a crap ton of boost like 30 -35 and barely hitting it almost 25. Well, I...

    I have a 2001 mostly stock 24v only 172k miles. I was just recently experiencing a waste-gate that was stuck closed. So it was building a crap ton of boost. I realized the missing coolant like 2 days ago the boost started 3. Today I filled up the Reservoir completely with coolant and checked...
  7. 98.5-02 Non-Powertrain
    Hello- I have a 98.5 with a stock radiator. Here and there over the past few days, my radiator will be dripping after my morning commute. I found (and tightened) a fairly loose hose clamp on one of the 3/4”(?) lines near the left motor mount, basically directly underneath the left headlight. I...

    Was checking oil and noticed it kept going up, I suspected fuel in oil and smelt it and it smells just like oil. So I think its coolant, its not very bad at all but definitely made the oil a little thinner and lighter. I notice coolant going down all the time but didn't think twice because of my...

    So just like my last topic, Im not sure where to start. This truck was always my daily, but starting in Nov21 I quit my job and started using the pickup to hotshot oilfield pipe. Limiting this topic just to my coolant and heating problems: Now that its winter, the problems are really showing...

    If you have already read my other topic, then great - you know the backstory Heat and coolant problems. But... I ended up seeking advice from multiple diesel mechanics, and they all bet on the head gasket. So, this entire past week, I worked on replacing it and I'm hoping successfully did so...

    I have a 2013 6.7 that’s been having intermittent high coolant temps. Just running 65 on the highway temps reach 135 and I pull over to let it cool. It seems like it will sometimes cool randomly like the thermostat isn’t opening but I just replaced it. Wondering if it could be the water pump...

    Long story short a shop replaced the engine coolant sensor cause it was leaking when it went in for trans work. Ever since the sensor has been reading 60 degrees cooler than it actually is. So around operating it reads 125 degrees. From my understanding 03 has a different sensor than the years...

    2012 Ram 3500, 6.7 Cummins, 68RFE, 4x4, SRW 295/60/20, 30hp tune with 56,000 miles on it. Today I noticed a small coolant leak underneath my truck in the garage. Looked up from under the truck and noticed that it was on the passenger side by the turbo leaking down onto the oil filter area...

    So not really much to say but i wanted to see if anyone out there would be able to tell me 100% but what had happened was i drove my truck for the first time in about 2 weeks, running fine then i park the truck and turn it off and coolant starts dumping from where it looks like to be the water...

    I have an 03 that I did a manual swap to. Can I delete all of the factory trans cooling system without any issues?

    My standpipe is leaking exactly where pictured in this photo. Is there any way to get around paying $800 for this entire assembly?

    2011 Ram 3500 Cummins. I need some advice on some issues I have been having. I started having some overheating issues at the beginning of the year. I put a new aftermarket thermostat in and that seemed to solve the problem for a couple of months. Then it started overheating again. Turns out I...

    I have a small coolant leak from the adapter that connects to the factory air bleed fitting in the picture. I included a photo of the blue plate so people can see what brand EGR I have. This leak happens on cold starts but seems to disappear after warmup. It is most noticeable if I start the...

    Flushing the coolant in my 1998 ram 2500 12 valve. I put green coolant in because that’s what we use at the shop (for cars and light pickup trucks). My buddy said your not supposed to use green coolant in deisel engines, what is the recommended coolant? Thanks
  20. 3rd Gen. Powertrain
    I have a coolant leak at the rear of the engine, above where the transmission mounts. It looks like it maybe the part that the coolant hose mounts to. Just replaced hose. Not that. Anyone have a diagram of what I am dealing with back there? Thanks, Bill
