[TR] Alumimium Heads

Aluminum heads are commonplace these days; any quality antifreeze will have the additives to protect aluminum.  

But be sure to follow the recommended change intervals, as the additives do wear out with time, even if the car is never driven.

There is some debate over whether “Dexcool” type antifreeze is good for old engines; I don’t know how much is true and how much is urban legend.  But I don’t use it myself.

Just watched an interesting video on the rise and fall of the Triumph Stag.  One of the comments was the need for special coolant due to their aluminium heads.   Never gave it much thought but my TR3 came to me with alumimium heads and I have always just used the regular antifreeze 50/50 from my local FLAPS.  Should I be doing something different, getting ready to winterize the fleet.
