Oiwa Garage Tech Note
"Flush the block and fit fresh hoses and a new cap with the radiator so the whole system is clean - a new core behind old, scaled hoses does not last."
Frequently Asked Questions
Should I replace hoses too?
It is smart to renew the hoses and cap while the system is open so the fresh radiator runs clean.
How do I know the radiator is bad?
Overheating, visible leaks or corrosion, and fins packed with debris all point to a tired core. Watch for coolant stains and a temperature that climbs in traffic.
