[6t7gto]

I have an 03 3500 drw with the dmax and i have a leak coming off the rear of the oil pan on the passanger side and i can not find were it is originating from. Now i had a slight problem last winter and no problem over the summer just when i started to use the heater again. under the hood just reaks of coolant. any ideas would be great thanks jason

My brother has an 04 d max and it was the water pump on his that was leaking. that would be my guess

Ryan, thank you for the reply. I guess we'll have to take off the skid plate to see where it is leaking from.

Can't see anything from the top.

It could be the water pump, but i beleive it is located on the drivers front of the engine, Could be the block heater (if equipt) or a leak off the heater lines......?

Common problem I am told. Was just talking with a friend who got rid of his 2003 for the same reason. He said he had to replace the heads, injectors etc. A defect exists. Supposed to be an extended warranty on this (200,000 miles he says) but some dealers act dumb about it. Also bad head gaskets are another common complaint.
