My 2006 2500HD LBZ Duramax pick-up just turned over 440,000 miles......
I starting smelling coolant last week, Turned out to be one of the Heater Core quick connects was dripping onto the EGR Cooler. Not a bad leak but I didn't want to tempt fate as these are known to blow apart at the worst possible time. Kinda surprised they lasted this long. Went to the dealer & got all the parts & 3 gallons of Dexcool.....@ $120.
Not really what I wanted to do on my day off, But I got it done before the Cowboy game Sunday!
These are a little tougher than their gas truck brethren......Take out the trans dipstick & plug it so you don't contaminate the trans fluid!! I use the OTC 6046 disconnect tool.
I use Hylomar Blue to dress the O-rings on the quick connects.
Changed the Air Filter along with the Fuel Filter & Water Separator on the Airdog lift pump which were way past due by @ 10,000 miles. I don't change the OE engine mounted Racor fuel filter very often as the last time the filter media looked new with 30,000+ miles on it.
Just waiting for the old girl to lay down with a major repair.....If it costs me more than a $1000....I'll sell it as is. Truck has paid for itself several times over & owes me nothing!!
