I concur. No louvers on the Cowdog.

Hood louvers! Several people with v8's in the M715 truck have found just propping the hood open an inch at the front will drop coolant temps 10°-15° on trails.

I have a separate oil cooler along with a separate transmission cooler in front of the condenser which is in front of the radiator. Engine oil cooler is air to air with the oil never going through the radiator oil cooler. The transmission cooler is also air to air with the fluid going through...

Glad you found belts that work for you. I have 3 CUCV belt systems on the road just about every day. 1 of them likes different sized belts than the others. I haven’t been able to figure out why. Without turning this into a Ford versus Chevy type debate. All of my Diesel engines eat any brand...

Ahab, I read a lot and research just about all the time. I took several boxes of old metal parts and bad fasteners to the scrap yard Monday. I found out $4.00/100 pounds is the going rate currently. But, I also found out the Cowdog weighs 6,974 pounds with me in it. That is 1800 pounds more...

1988 k3500. 6.2/TH400/NP241. 14 bolt semi float. Pm me your email and I can tell you more. Yes, speeding up the water pump probably would help. I’m kind of stuck in “in between land” on this issue. Square body truck designed for gasoline engines, Diesel engine designed for 55 mph speed limits...

I have been driving and driving it. Last Sunday I was meeting Colton for bonfire cut in the middle of nowhere. He had sent me an address that was wrong. I found myself 15 miles from where I needed to be and about 3 minutes to get there. Nothing but dirt roads with 90° turns. I discovered some...

One of the early multifuel TM's actually said something along the lines of. If the truck is smoking, dripping, leaking, running eratic or just about anything else. Load to max gross weight and drive 100 miles. Then recheck to see if problem still exist. These things like to be run hard.

Open or closed knuckle doesn't effect the castor measurement. I have the stock closed knuckle D60 on my M715. When measured by a Hunter Engineering alignment machine, I have 4.5° castor. You didn't state in the first post that you were trying to set up stock axles.

Somebody sure did care for that truck. Military looking horn too.

Thanks for posting that Rory. I was mentally composing how to put down the same basic thing you did when I saw that you had done it. Only good experiences with them for me. I am also 2 hours away if you figure in traffic.

Yep, the injectors are wrong inside. Did you by chance get some of the "marine" injector internals off an online auction site? They are for the shorter 6.5 injectors, not the 6.2 injectors. Just a little bit of size difference gives you that leak and noise.

The CDR is supposed to be hooked up before the filter. There are several versions of the CDR. 2 versions that bolted on somewhere and then 2 versions that fit in the valve cover on the 1988 and newer engines. The valve cover versions are turbo and non turbo. There is a difference. There...

That is the same place Andy. I just couldn't remember the name and have no paper work hear in my class. Glad you got it working.

The 4L80E is controlled by a Transmission Control Module. Full range of travel by the shift lever on the column can't be used unless the shift rod from the column to the transmission is lengthened a bit and maybe bent a bit. The arm on the 4L80E will have to be swapped with the arm originally...

Do the vent test procedures posted above. If it still happens and if running with the tank cap off causes you to drive ok and then start loosing power and top speed progressively. Use a pair of pliers to pull the red clamp up off the hose on the radiator end of the IP. Pull the hose off the...

Good. Accessories turned by the grooves in the serpentine belt with grooved pulleys turn crank shaft direction. Those turned by the smooth side of the belt with smooth pulleys are counter rotating.

I like Permatex Number 2 gasket maker for those plugs. The white tube with the really sticky black goo. Being NPT, they shouldn't need sealant, but as pointed out sometimes they do. I have never used it on my fuel tanks though. Just the gear oil plugs.

Have you pulled the return check valve from the top of the IP to see if the glass ball is covered in little bits of black things? It sounds like you have a fuel system vent issue, however. It could also be an IP issue.

Power steering pumps turn the same direction as the crank shaft on both systems. Only the water pump is backward.
