Flip up radiator cap.

[Skeezixx]

Hi, I'm new to this forum and I have a newbie question.

Back in the 60s I had a 31 Tudor sedan and let it get away from me.

Years later I found I missed it so today I went to check out a 30 Tudor which is owned by a widow ( in a garage for 30 years). Upon inspection, I was embarrassed to find I did not know how to operate the flip top radiator cap with a motor meter installed (mine had a stock cap). I'd like to poke my nose in there and see if there is still any water left.

What's the trick to opening them?

Also, the gas shutoff valve inside the car is stuck in the horizontal position (off I presume) so my attempts to start it with a battery charger were useless.

I am to return later this week to "get it running" with a new battery and some fresh gas.

Any advice on steps to revive an A which has been sitting this long would be greatly appreciated.

Thanks,

Ken
