I know it’s been awhile, but I have been working on the truck. When it got really hot, 102F, the A/C sucks, and the engine got hot at red lights. I’ve heard this about these trucks from a few forums. I started to investigate.
1st off, the fan shroud was chopped. The previous owner and his redneck ingenuity, removed the bottom section of the fan shroud to replace the water pump, with out removing the fan. Needless to say the fan did not pull air correctly at idle. I replaced it.
I also added a helper fan to push air through the condenser:
I don’t think it really does 2500 CFM as advertised, but the price and size was right. I even though I only needed 30 amp relays, I found a great deal for 5 70 amp relays and harnesses for only 15 $$! Here’s a picture of the relay tapped into the fuel pump hot wire ( the fan relay clicks on when the fuel pump comes on, with the key turned in the ignition)The biggest improvement I made was the foil duct tape to seal the air gaps between the radiator and condenser. This ensures that the air is pulled through the condenser and then the radiator. Now that it’s all done, the engine doesn’t run hot sitting at stop lights, the A/C runs great at 98 degrees and below. There seems to still be a knee curve on the A/C performance above 98 degrees F, where the thing works as hard a s possible, but can’t remove and more energy from the air. I’ll check the 143a coolant levels in the coming weeks and see if there’s a problem, but the system might have reached its limit.Thanks for reading.
Only 49$$ and this will help keep my differential from bobbing up and down. I don’t need anything fancy it’ll be stock +. Although a ladder bar/ track bar system would be nice, this will be easy and simple, and not need changes after I put on new/ refurbished leafs.
I finally get a chance to work on the mower this season. It’s that time of year when the grass is taller than the dogs.
I poured in some sea foam to get the carb cleaned out, the engine started and sputtered out. I could not get it to crank properly. It kept acting like the valve lash needed to be adjusted, but I just did that:
Next I checked the oil, there was bunches in there, but not just oil. I drained it out and found about half a gallon of old oil, fowled fuel, and possibly water. Looks like a carb needle was stuck open and I left the pet cock opened at the end of last season, so all the fuel drained into the cylinder and seeped past the rings into the crank!
I refilled filled the oil, added fresh fuel, and it cranked right up and ran very nicley. Now I need to replace the fuel lines and filter, the dang ethanol eats them away and I can see little black chunks coming off in the tank. The deck belt is also stretched and the battery needs to be replaced.
Needles to say, I pay about 70 plus dollars every year, just to make this machine run again. It’ll get going, but its to wet to mow today anyway, so maybe next weekend I’ll actually get to chop down the grass.
I was digging around the innerwebz and just found this site. MagnumSwap.com has a lot of good info on the LA-318/360 and Magnum 5.2/5.9L engines, and what parts they can swap between the two for a conversion.
To keep the adaptor in the hole, I found an old nylon ratchet tie down and wrapped the 4″ side fo the adaptor with it. Then I covered that with electric tape and pressed it into the hole by hand. It holes nice and snug.
