The radiator hose which connects from the radiator to the block. What is the path of the antifreeze? Reason I ask is I put some radiator leak tablets in the hose to dissolve and cement the radiator cracks but then wondered if it could damage my motor.

 

Those aluminum fillers that you put in your radiator actually clogs up your heater core. Your better off just getting a new or used radiator. Its better than having your motor overheat and blow a head gasket or worse your motor.

 

my motor did overheat temporarily as the gauge needle went up to about 65% of the way up b4 I shut off.

do you think i'm fine?

 

i would say that you got lucky, yes. good thing that you caught it when you did.

 

oh boy.
