    I looked at the fans they had, I just need to measure what size will fit the cooler and order one, along with the wiring. I'm sure I could find a 6 AN fitting for the temp sensor to go in line with the hoses.

    No AC. It was inoperable anyway, so I ditched it. I had already axed the dryer to make room for the HE351VE. Good thing there are 4 windows to roll down instead of 2. 🌬🌬🌬

    Next step with the transmission cooler for sure is adding a fan. If it won't fit where it is behind the grill, I'll look at relocating it. The CAC is sitting where the AC condenser was, so I have that going for me.

    It is a used Cummins radiator, it could not be fully flowing or gummed up somewhere. I didn't want to put holes and new ports in a new radiator until I knew it would work, so I started with this one. I'm considering going back to an aluminum GM radiator and modifying the intercooler or going...

    Roughly 70 degrees ambient.

    I upgraded the transmission cooler to a larger one when I did the CAC install because I'm using the Cummins radiator with it and got rid of the secondary cooler in the stock radiator.

    I put a 2nd Gen Cummins CAC in the cooling stack earlier this year. IAT was never above 110 degrees under max boost, approx 16 psi. All of that heat removed from the pressurized intake charge is now going in to the radiator though, which probably isn't helping the issue.

    Used the truck to pull my 7500 lb camp trailer approximately 400 miles round trip to and from elk camp. It didn't break any land speed records, but made it there and back. The Sisters on I-80 east of Evanston were a crawl, but I expected that not wanting to push things to failure again...

    Yeah the T valve, I deleted it and the FFM when I installed the Airdog.

    Running an Airdog pump and filters on the frame with 1/2" hose direct to the IP, no more bleeder valve.

    Especially if they were already old and were just taken apart to replace the heads.

    Been driving the truck, still getting a drip from the front of the motor. As dark as the drops are I was thinking oil, but after a while the drops are spreading out thin so now I'm thinking fuel that is picking up oily residue from grime on the front of the engine. I'll be looking at the hard...

    After daily driving it for a week, I see no evidence of coolant in the oil. It is pretty black though, even after just a week.

    I gave them a brand new tube of Optimum Black with the ARP torque fluid. The tube didn't come back with the core parts. Draining the oil now... 🤞🏻🤞🏻🤞🏻

    Getting a pretty good oil leak from the front of the engine. The shop that did the heads put in a new front main seal when they did the fluidampr, hoping they didn't screw it up. Another big concern I have is they didn't put sealant on the studs before threading them in to the block. I checked...

    I was looking the old heads over today, and there don't appear to be any damage or cracks. I may have wrongly assumed they cracked and/or warped to cause or contribute to the pressure leak in to the coolant system. I havent put a straight edge to them yet, but they don't look warped either...

    Probably just going to have a shop do it honestly. I used to be able to do my own projects, but I have come to the realization that spare time is too scarce to be able to dig in and do things like this myself. Maybe after kids grow up and can be more self sufficient.

    Truck is home. The oil leak ended up being the driver side valve cover gasket. We think that the tick must have been air in the fuel lines, it's gone now. Looks like the rear main seal is going to need to be done soon now, but I knew that already. It's running great, can't believe how much the...

    Thought I was going to get the truck back today, no go. Got the call that it was ready, so I went to get it. Started it up to leave and could hear a tick like an exhaust leak or valve train? It increased with RPM so definitely in the engine. Go back in to get the tech that did the work and have...
