JHTrucking Posted March 23, 2017 Share Posted March 23, 2017 Is it worth rebuilding my engine on my 2005 Mack cx613 with a 460 ASET engine, my biggest problem is overheating. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted March 23, 2017 Share Posted March 23, 2017 If you plan on keeping it yes. How many miles are on the engine? What's your oil usage? But I would first find out the reason for over heating. Pull the screen out out the "Y" pipe and pull the water pump off and check the water pump housing for putting . Have radiator cleaned and check fan clutch operation. Is it a air fan or electric viscous? Quote Link to comment Share on other sites More sharing options...
JHTrucking Posted March 24, 2017 Author Share Posted March 24, 2017 850,000 miles, I go through 1/2 gallon of oil weekly, I pulled the screen, the water pump housing does have putting, haven't checked radiator, the fan clutch is electric.

br549 Posted March 25, 2017 Share Posted March 25, 2017 2 quarts a week= $6.00 oil, Overhaul =$10,000-15,000 dollars, don't know how many miles you run a week, but that's not much oil. I had a 2005 AC427 that used 2 quarts of oil a week at about the same mileage and sold it at 1285000 miles on it and it uses about 4 quarts a week, had no other problems with the motor and I figured oil is a lot cheaper. It ran about 2500 miles a week. The guy that bought it now has 1375000 miles on it and still runs good. We did drop the pan and put rod and main bearings in it at 750000 miles. Like Pro said, find the heating problem. We had the electric controlled fan on ours and it started heating up and the fan was not kicking in. When it is running hot you should be able to hear the fan kick it. Quote Link to comment Share on other sites More sharing options...
carlotpilot Posted March 25, 2017 Share Posted March 25, 2017 when it starts using a gallon every 500 miles think about an overhaul Quote Link to comment Share on other sites More sharing options...
