You are screwed! Get that radiator flushed by a profesional ASAP! ANOTHER SUGGESTION DO NOT RUN THE MOTOR HAVE IT TOWED TO A PROFESSIONAL. IF YOU DID RUN THE ENGINE GOODLUCK BUDDY HOPEFULLY IT DIDN'T AFFECT THE ENGINE IF SO YOUR GONNA HAVE A HELL OF A TIME REPLACING ALL THOSE HOSES AND YOUR RADIATOR AND HAVING YOUR COOLANT LINE REPLACED.
Nothing will happen if you drain the cooling system and replace the coolant.
You drain the oil immediately. If you run the engine with coolant mixed with the oil you will do serious harm to the engine. If you continue to drive it in this condition you will destroy the engine.
Change oil and filter
Have the coolant changed immediately and you will be ok.
There are a couple of things that can cause oil to get into your coolant reservoir. A blown head gasket or a broken piston ring are the most common causes.
The oil filter on a crafter is to the left of the engine under the coolant reservoir.
Do you have an oil cooler? I have heard that is a possible cause, as would be the head gaskets.
if there is oil in the coolant system it could be a crack in the intake, a ruined intake gasket, a cracked cylinder head
Blown head gasket, cracked hed or cracked block
If there is oil in the coolant reservoir that means that the oil has gotten into the cooling system. The most likely place for oil and coolant to meet is at the cylinder head gasket. I hope this isn't the case because it's a very expensive repair.
Down on what? Engine oil, check the dipstick. Coolant, check the reservoir.
