Hi fellas, can I get away with fitting a smaller radiator on my 404 1800? By smaller I'm referring to the regular one used on 404s(1600). Just to be clear, we had limited edition 1800 404s in South Africa with the wider 504 radiator. Problem is my 404 is automatic and when one is having battery issues I cannot crank it with the hand crank due to the radiator blocking the crank hole. If the smaller radiator will cool the 1800 just fine then I will go for it and I will need to get someone who can make me a hand crank, it's imperative to have this in an automatic car I believe. Please advise.
