DENSO Auto Parts Radiator P/N:221-3135
DENSO Auto Parts 221-3120 radiator for the 2001-2005 Lexus IS300 6-cylinder 3.0L moves engine heat out of the coolant through a thin-tube aluminum core. It is a new replacement for a radiator that leaks or lets the engine run hot.
A high temperature reading or coolant leaking from the core or tanks can mean a radiator is failing. A thermostat, water pump, coolant hose or radiator cap can be behind those signs too, so track down the cause before you buy.
This new OE-quality radiator is a direct-fit replacement for the 2001-2005 Lexus IS300 6-cylinder 3.0L, which takes one.
