[/B]My new Behr radiator just arrived. I changed the water pump and discovered slug and small pebbles of coolant in the pump and block ? I do not want to plug up my new radiator. All the other components of the coolant system are new. Should I:
a) put on the old radiator and flush the system, then put on new radiator
b) put in the new radiator and flush system without worry
c) flush the block in an alternative method
What would you do ? a, b, c, or d (what I didn't think of)
Recommended brand of engine flush ?
