coolant question

Can someone please tell me where the drain plug for the radiator is on an 03 450?

There is no drain plug for just the radiator. Instead, the entire cooling system is drained by removing the lowest water pump cover bolt. :thumbsup:

^^^^^ what he said, at the water pump. Remember to loosen the radiator cap too and tighten the bolt prior to refilling again.

Got it. Thanks
