Default Re: flathead engine temps?

read what our friend said [ the coolant is about 1" over the core " not full so my guess is where he is shooting the hoses there is NO coolant only air so if he tops off the coolant and retries bet he gets totally different readings Air pockets can create absolute havoc they cause overheating yet read cold [due to lack of heat transfer] and worst of all if they shift rapid temp change and cracking
