What can be done about rust on a radiator
I was looking at a diesel coach the other day and noticed rust on the bottom of the radiator. Not a lot but it was there. Does that mean a new radiator or having the current one recored?

They stopped making steel radiators a long time ago. Your radiator is probably made of aluminum and brass so any rust you see is either rust coming from your engine block and leaking through the radiator with the coolant or rust from some exterior bracket. If it is coming from your engine block and leaking out, the only solution is to remove the radiator and have it checked to see if it can be repaired or if it needs to be replaced.
