[TR] Radiator Caps

[Keith Stewart]

So, the TR2 through TR4A engines all have the same derivation. The TR2 through
TR3A engines use a 4lb cap and the TR4 through TR4A engines use a 7 lb cap.
What is the deciding factor that makes the difference? Is it the rad? Is it
the heater core? Something else?

Curious minds want to know :-) Thanks.
