Hello! I've got a 1993 GMC Sierra 1500 with the 4.3 v6 (122,000 miles), manual, and I just got it running last night after it was given to me a couple years ago. I had removed the radiator and water pump and flushed out the engine block and radiator with water not long after I got it. Well I put fresh coolant in last night, got the thing fired up to get the coolant circulated, and this is how it's looking. The oil looks perfectly fine tho, the green in the pic of it is just from the big outside light on the house.
