I purchased a 08 5.7 dc 3 months ago with 24k on it.I was changing the oil today at 26k and when i took the skid plate of i noticed pink antifreeze had been leaking down the front of the motor so i made appointment to have the water pump done Thursday at Toyota.Seams awful early for a water pump.Is it the pump or gasket.Will they use a updated pump or gasket.
