In this area (picture) its leaking quite a bit of coolant underneath the car it is heavy dripping. Could it be the water pump? Car is over heating .It almost looks like its missing a screw or something where the coolant is dripping.
yes that is the water pump weep hole you need a new water pump that hole leaks to let you know that the ceramic seal inside the pump has failed
Water pump. When the bearings go they allow coolant to seep out.
Looks like it needs a thorough coolant flush and a water pump.
You're trouble could be one among two.....The gauge cluster could be bad and want exchanged out(the dealer does no longer restore them),or the gasoline sender(or flow/level sensor)which is attatched the the gasoline pump(does no longer include pump)could be inaccurate.The vendor or repair facility easily makes use of your old sender when changing the pump(which is a dumb thing to do once they have already got the tank out of the auto).And oh incidentally........A GMC is nothing more than a re-badged Chevrolet....And were considering that 1996 once they stopped making GMC seperate on the truck and bus plant and diverted all manufacturing to the Chevrolet crops....Equal construction line,distinctive title plates,do not let anybody fool you about GMC being reliable grade,no more durability...Just more money !
