Heater

[smokeshow101]

I was wondering what could be making my heater blow cold air when i come to a stop or like when i let out of the gas and start slowing down. And when i am pushin on the gas and going it blows really hot???

your coolant is low ,check reservoir if it is low ,that is your problem ,i cant say for sure but i bet the short hose runing from the egr cooler to oil cooler is leaking ,you probably arent seeing the leak ,because the engine is burning it off before it its the ground , seen this 50 times , anyway to star off with ,just check coolant level

I concur with Scott! I'm no tech but I know I've seen (and experienced) these same symptoms before. It's a good time to treat your coolant also if you have not done it yet. Good luck and let us know the outcome.
