coolant smell

2008 F450 6.4 KR. I had the exhaust up pipe leaks and the dealership replaced these by removing the cab. I knew they had to. However in the process of putting the truck back together they cracked the plastic nipple under the coolant tank and it developed a leak on a trip 1000 miles from home. A dealership in Salem, IL repaired the truck with no problems. They flushed the coolant and added the proper level and installed the recall hoses and "t" fittings on the coolant bottle. After I got back home I had the dealer reflush the coolant and everything is great with the leak. However the truck has a horrible odor. It came from the coolant leak in the begining. No leaks now but the left over coolant may be causing the odor I dont know. Please help.

Also the truck has the latest PCM program from Ford. (the truck is bone stock) The cooling fan comes on and cycles when it is 40* outside and the truck at normal operating temp. and no load just the naked truck. It cycles loaded and unloaded at 55-70 mph and the cycle is the same loaded or unloaded. is this normal PCM strategy or is something funny?


Final question. I live in North Carolina. NE corner. What dealership has the best Powerstroke Tech. in NC or either Virginia.

thanks guys

First my truck had the smell both time the rad was replaced. I just kept a lose watch on my coolant level untill the smell was gone. Second, I have the latest reflash from Ford and my cooling fan only comes on when I am towing heavy in warmer climates, usually on the longer hills. Sounds to me that there is still a problem. Only speculation of course, but maybe air trapped in your cooling system, or something wrong with the thermostat. Could be other reasons, but that is all that I can think of.

That could be a problem. I know a lot of guys on here with their Spartan tuner forget about the OEM gauges and look at the DashDaq. I remember reading a thread that some guy's truck was overheating on he DashDaq but fine on the OEM gauge. He had a screen in front of his grille and it was clogged with bugs I think. So maybe there is also bad gauge in you truck. Mine will get hotter, then the fans kick on and it goes back to normal pretty quick. Is your coolant level ok? I was also thinking that they maybe put in the right kind of coolant. It shouldn't make a dfference, but you never know with these new high tech trucks

coolant is motorcraft coolant and is up to the proper level it is not leaking at all. it has been pressure tested for about an hour at a time. the truck is stock and has never had a tuner. it is bone stock.

More than likely its the EGR cooler, they will leak when they are hot and seal up when they're cold. Good ole' expanding and contracting!
