Ok, Isuzu in Sanford Fl is only dealership near me to deal with front of motor coolant leak. Dealer tells me if they break it down and water pump is not the issue I will have to pay for all labor. Question is what else could this be at front of motor under timing cover? Is there any other possibilities? I can see Isuzu screwing me in this if I am not knowledgable of this issue and possibilities. Anyone who has had this done please advise. Thanks
