Info needed: C60 radiator overflow tank connection

[Ken Thomas]

Hi everybody, I am getting my C60 radiator re-cored. Could anybody tell me, or post a picture, to show how the overflow tank connects to the radiator. I assume it connects to the radiator over flow pipe. I further imagine that the over flow pipe would be shortened [probably near the top tank]. I have to get this right & none of my old radiators are of any help with a clue, as they all have overflow pipes to below the bottom tank. The overflow tank is above the front of the mudguard near the side vent, on this vehicle.

I am told that this is not a pressured system & that it has a plain cap i.e. no spring & valve under the cap.

All help will be appreciated.

Hi Ken

Which Pattern 12 it comes off the filler neck, 13 off the top tank, but don't forget get the steam relief line coming off the back of the block which connects to the top tank as well.

Both the recovery tank and the steam relief are very important to making cooling system work correctly. I run all three of my CMPs with the steam relief open just a little bit which first vents any steam or air out of the back of the block, it also allows coolant to start circulating when the thermostat is closed fully when starting, helping to stop hot spots in the block.

When the coolant recovery system is working as designed it really keeps the radiator full at all times. You may have seen the photo of my Pat 12 running with an clear bottle attached to the vent on the standard coolant recovery tank. This is how I charge the recovery tank with coolant so that it always as some coolant whether engine is cold or full hot.

Cheers Phil

Thanks Phil, could you give me a diagram or photo of the overflow pipe from the centre of the top tank to the point where it connects to the hose to the overflow tank. I want to determine the shape & length of the copper pipe & how it is supported i.e. where it may be soldered to the top tank or side strap before it connects to the hose. Thanks Ken.

Hi Grant thanks for that. Exactly what I needed. I will take it to the radiator shop tomorrow. Ken. And thanks again to Phil.

Hi Ken

This is why I have enjoyed MLU for all these years, a question gets asked and answered in short order. Grant beat me on the photos of the Pat 13 Radiator recovery and seam relief tube locations, so below is the top tank of Pattern 12 Chev Radiator which is different.

Please post some photos of your new radiator.
