VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 questions about the 207 c.i. inline 6 in my '34 Chevy Truck

Hey y'all:
anxious to get started on my '34 Chevy Truck project. I'm reading everything I can get my hands on, while I'm waiting for my manuals that I ordered to arrive.
I came across the following on Hemmings:
"The head also incorporated eight small stamped copper nozzles pressed in near the exhaust valves, used to direct streams of water at the valves and seats, keeping them cooler."

Does this mean there's a water reservoir somewhere that'll need to be filled for this purpose?
How do I know if this system is operational? What happens if it's not?

What other nuggets am I gonna find? haha.

No, they act like jets and send waer to the hot areas arund the valves.They are pessed into the head casting and no serice is required.

They use the water from your radiator.. that is circulating through the engine...

that's the key that was missing for me.

I'm going to guess that these were not pressurized coolant systems? So checking the radiator level was a regular/ daily thing?

1948 was the first year to have a pressure cap.

It was common years ago to CHECK THE OIL AND COOLANT EACH TIME GAS WAS PURCHASED.

i Had my 1934 CAR FOR 40 YEARS AND 25,000 MILES AND NEVER FOUND IT NECEAARY TO ADD WATER. hAD A 160 thermostat a 50/50 antifreeze mix.

Never add water with the engine hot - It will crack the head.
