As I sit at my computer thinking of the latest weather report and hurricane
Wilma heading for south Florida it occurred to me that winter is knocking at
our door here in the mid-Atlantic area. I am sure your T-type is safe and
secure wherever you have it stored. But had you thought of the possibility
of damage that can be happening while it sits there waiting for next season?
Of course an oil change is in order as is checking and adjusting the tire
air pressure. Topping off the gearbox and differential might be worthwhile
too. But what about the coolant? The antifreeze and water mix in the block
and radiator often go unattended and can become a pretty nasty solution, all
by itself, over time. This tip I bring to you is from an acquaintance in the
Morgan world that is a very prolific writer of hints and tips for Morgan
sportscars. Fred Sisson's book "Morgan Driver's Bedside Reader" is chocked
full of all kinds of information that can be transferred right over to our
T-Types.
Fred writes that old coolant, working with the dissimilar
metals in your car's cooling system can create a "battery" that can
deteriorate the metals in the engine and radiator. The radiator is of a
thinner metal and is usually the first to go but it takes time, several
years in fact. Fred's tip is to use a digital voltmeter to check for this
electrolysis taking place. Connect the - lead to the radiator. And then
dangle the + lead into the coolant. A reading of 0.2 volts dc is good. 0.3
to 0.6 is marginal and any more would require a drain and flush and
replacement of the coolant. Last I checked, regular antifreeze is $10-$13 a
gallon. It's not cheap anymore that's for sure. Also, please dispose of any
used coolant properly and safely. Everyone knows it is lethal to anyone or
anything that would drink it. Pets and other animals seem to be attracted to
its sweet taste.
