[Tigers] Radiator header tank question

[CoolVT at aol.com]

Is the overflow bottle just fed from the rubber tube  on the stock overflow 
tank? Does it have to be sealed in some way? Any pictures  or diagrams 
available?

I second that and it is an easy  installation.   I installed a
coolant overflow bottle many years  ago.   The bottle is just a second
Sunbeam windshield washer  bottle mounted and squeezed into the left front
corner in front of the  header tank.   I did not change the stock cap on the
header tank  and it has work just fine for the past 20 years.   The  coolant
comes out when hot and is sucked back in as the system cools  down.  Maybe I
was lucky with that cap, many have said it would not  work correctly with 
the
stock style cap.

The reason I  installed the recover bottle;  I was driving an event
at Watkins Glen,  in a right hand turn the coolant blow out onto the left
front tire creating  massive understeer.   Fortunately this was also an up
hill turn  so my speed quickly dropped and tire traction returned.   I  did
not put a tire off track but my next stop was the Pit area for the rest  of
the afternoon.  The following year it was mandatory for all vehicle  to have
a catch can at this driving event.  Safety first and  always.

Just a comment about the coolant level in the cooling  tank.

If you add an overflow tank and a cap like a Stant with a double  seal  and
a toggle relief valve, you can keep the tank and  radiator  absolutely full
at all times so that;
*   the radiator is always full of coolant and all of the   radiator
core is used.
*   there will be no  aeration of the coolant to degrade the waterpump
efficiency.
*   when the engine gets hot, the over flow coolant is saved  and
returned to  the tank during cool down rather than on the road or  track.
*   the overflow tank becomes the place to  check the coolant level
without  removing the cap.
