Im considering a purchase on a 2018 Ford F150 and it comes with orange coolant. Ford has no more old stock of their orange left over, and I am aware I can buy valvoline or zerex branded orange deathcool and use that instead. What I want to know specifically is because there is no way to drain the entire engine block, can I switch over to the yellow ford coolant with the cor guard?
I will not flush a system that has 140k on it, I just want to do a dump and fill. Will the little bit left in the engine hurt anything?
