Question: smell in cab sometimes
Question
i thought it was an antifreeze smell, a sweet smell, but now i wonder because i'm not losing any antifreeze fluids from the radiator. it seem to be happening more often and i notice it when i excelarate, like on hills. all the gauges on the dash are normal but i have noticed my mpg gauge is slowly increasing but i though that was because i had the tires rotated and rebalanced 2000 miles ago. the other thing i've noticed is if it happening and i have the windows up i can turn on the ac and i can't smell it. also, i can't smell outside of the truck.

MasterMaybe a pinhole leak in the heater core and probably the only way to know for sure is to have the cooling system pressure tested to see if it holds pressure also I found this in Repairpal's common problems for your vehicle The cooler for the EGR valve can leak internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine. A friend of mine has a 6.0 diesel and he was having problems with the EGR cooler and had it replaced under warranty

Visitor, November 14, 2010, 12:12ReplyI replaced the oil cooler and the Antifreeze smell went away.
I found that the coolant side of the cooler was filled with what looked like
"The coolant had failed". Or had broken down and turned to mud.
Not a fun job to replace the oil cooler but I did it for around 200 bucks. I cleaned the coolant system very well and no smell anymore.Flag ThisLike0
