Well,i just made the last payment on my 99 2500 5 speed,so ishould have expected something like this would happen. Anyway,now the head gasket is leaking antifreeze from the front of the motor(rite in front of the exaust manifold) I feel like this is a job i will let someone else tackle,however im still wondering if there is anything tricky about this job or anything that i should watch for when the gasket is being replaced? How many hours labor should i expect to be charged for?
