AUXILIARY RADIATOR

[prop]

I have discovered a leak in my aux rad. I have taken it off and just linked the hoses so there will still be a flow. Now I have to consider if I am going to build another from a Mocal oil cooler or find another rad to use like a motorcycle rad or just leave it linked. My thoughts are I don’t really need it as it is only effective when the car is moving. I have never had any problem overheating when moving even when I removed the aux radiator for a season and blanked off the pipes. My overheating is only when stuck in traffic so no air flow through the aux rad. So stuck not moving with engine running it’s not contributing to cooling. Any thoughts anyone?
