Hello and thank you for using justanswer.


Which engine do you have in your truck?


How bad is the leak, is it seeping or pouring out?

Customer: replied 5 years ago.
Just a minute while I go look under the hood. It a Vortec V8 It is a very slow leak and the low coolant light comes on , it takes a few days before the light comes on after we add coolant.

Was this the older body style truck with the 5.7 or the newer body style 5.3 liter?
Customer: replied 5 years ago.
I don't know How do you find that out
Expert:  Dave Nova replied 5 years ago.
You can either look at the emissions label under the hood, or let me know what the 8th digit of the VIN number is XXXXX I can figure it out.

The VIN is 2GCEC19T4Y1180194
Expert:  Dave Nova replied 5 years ago.
You have the 5.3 liter engine. The most common place for coolant leaks is the water pump. Since you have already replaced the water pump, you will likely be leaking coolant from the radiator end tanks. Look carefully at the tanks for small cracks, you may need to lean the radiator back to check the front side of the end tanks.
