Hi, In the middle of of taking both my radiator's out of my 348 for refurb. I've got the left hand one out easily enough but have a question about taking the right hand one out. The top radiator appears to be bolted to the oil cooler which is underneath. The bolts also appear rusted so it looks like the oil cooler needs to come out aswell. Do I need to drain the oil before disconnecting the two big hoses which are connected to the oil cooler ? Cheers, Simon.
