i need some fan clutch help. local a/c place swapped out my oem fan clutch and replaced it. didnt ask them to but they did. now a/c temp rises at stop lights. the fan clutch they put on, the fins are much shorter than the fins in the picture in @Mopar1973Man "cooling system flush" article. does anyone know the brand/type/part number you have on your truck. i got 2 numbers from parts look up tool, need to find the proper fan clutch and get it cooling correctly again. the one i looked at from autozone have short fins also. for comparison, belt is 1-1/16" wide first picture is of @Mopar1973Man fan clutch fins second picture is from thoroughbred diesel site third and fourth picture is what is on my engine

Hey guys, just reaching out before I start spending some money. I have a 2nd gen dodge 5speed 3.73 gears with mild build. I recently bought a 37’ toy hauler that weighs close to 9,000lbs empty. I live in Colorado and when I tow this thing is usually over some pretty serious passes. As summer is here I’m struggling keeping my engine temps under control. I do have a high flow water pump, new oem replacement radiator and 190* thermostat. While pulling up RIO with my RZR in the trailer I got a little out of control on my temps. Probably 225*. My EGTs were getting a little hot at about 1250. My truck was getting hotter sooner with my antifreeze/water ration about 70/30. I took some advice from my father who ran heavy duty diesels for 20plus years and am running 25/75. As he said it will still get hot but not as quick. He was right. Anyone done anything to their truck to keep the temps down that actually worked while pulling heavy? I’m guessimg my truck and trailer combo was close to 24,000lbs when loaded.

Recently bought my 2nd 97 12v. Currently has a long warmup cycle 20 miles + and was going to replace the thermostat (with a big block per Michaels suggestion) Turns out I have a small amount of oil in my coolant :sad4:. both the thermostat and oil cooler have formagasket and the heater core was recently replaced. I am suspecting that the oil cooler was recently checked or replaced and perhaps the form in place gasket is not so good. Question is what year make and model thermostat do you suggest? Secondly does the oil cooler break down and leak with age like the heater core? I do not seem to have coolant in the oil and am hoping it's a problem that replacing the gaskets on the oil cooler will fix. Hopefully not a blown HG. Any suggestions welcome.ThanksRich

See attached file. I'm trying to figure out the path of the fuel flow within the VP44 injection pump (IP). I'm interested in the slight possibility of additional cooling for the IP. Does anyone have any other pics or drawings or diagrams they can upload? I've done a bit of research on forums and I've talked to BlueChip at lengths. The VP44's computer sits on top of a heatsink or is integral to it, this is bolted to the IP housing, and the diesel fuel passing under the heatsink cools the computer. There is a vane pump at the inlet of the VP44. The "ww.chinahanji.com" drawing is helpful. I'm thinking the area directly beneath the computer, adjacent to the inlet and outlet ports is a cavity and inlet to the vane pump. The fuel enters the cavity thru the inlet port, the cavity is pressurized to 14 psi via overflow valve (or pressure release/check valve, whatever you want to call it) that is integral to outlet banjo bolt. A portion of the fuel is taken from the cavity by the vane pump and fed to the high pressure rotary section of the IP, the rest is returned to the tank thru the overflow valve. This flow of fuel, most of which is returned to the tank is what cools the computer. Does anyone know what the bottom the computer/heatsink looks like?- is it finned or flat? The smaller cavity that the heatsink/computer also covers is shown with what looks like a wire ribbon passing thru and has a seperate gasket. Does anyone know if this is also filled with fuel? Please, are there any VP44 guru's out there that can correct me? VP44 pics1.doc
