Anyone ever have there vapor lock on there coolant, or the line freeze up going down by the radiator cap. Where would the Coolant go from the radiator if it can't go out the overflow?

Not sure if I understand completely but, I would think if the overflow was plugged somehow, it may build pressure and the cap would pop. Not sure how many pounds our rad. caps are rated for.
