Overheating and loosing Power

rdebolt · #1 (**permalink**) 08-20-2007, 08:13 AM

I have a 99 F350 Crew Cab Long box. Superchipped, 4" Exhaust, K&N Air filter. I have been having Engine overheating problems that are gradually getting worse. Also the Power is deteriorating as well. When pulling a trailer up a hill my exhaust temp climbs to 1250 and engine overheats. Fan clutch and thermostat are OK. I used to run 1100 exhaust temp with no problems at all now temps are climbing and power is lacking. If I back out and keep exhaust temp at 1000-1100 I do not have engine overheating problems. Any help would be GREATLY appreciated.

I say clean the radiator and flush the cooling system. When I say clean the radiator I mean clean it, I had the same problem. I ended up removing the radiator and taking a pressure washer to it. I flushed the cooling system at the same time. Then I refilled with new coolant and I have had no problems since.

pull radiator off and send it to radiator shop to be rodded out. most of the time (if it is aluminum radiator) it will need to be replaced. this should solve your problem.. good luck
