While putting the final touches to the DHC's engine
bay already two months ago I also gave the water pump a quick look. And at the
time there were clear traces of coolant from the infamous slot underneath the
water pump. A tissue wedged in the slot would be soaked within 24 hours. But
during a circa 300 kilometre tour over a month ago all was normal. When I set
of in the morning there surely was a leak. With the tissue stuck in there again
being completely soaked in coolant. But there was no significant drop in the
coolant level in the header tank. So I decided to ignore the leak and enjoy the
driving. And when I returned home some 5 hours later the slot in the engine
block was completely dry. Even after the engine had cooled down there still
were no traces of coolant in that area. So it looked like my initial thoughts
on the problem were correct: due to the cars idleness the mating face of the
water pump's seal had corroded slightly, thus causing the leak. And using the
car more often should get rid of the corrosion and the leak.
But when I wanted to take the car for a spin last
Friday evening, a quick inspection before I set of again showed a tiny trace of
coolant from the slot. But more worryingly, the coolant level in the header
tank had dropped considerably. But then I remembered that while changing the
header tank recently, the hose between this tank and the radiator developed a
leak (hose clip slightly loose). And since I hadn't topped up the coolant. So I
did it now! After which it was time to enjoy a lovely evening of topless
driving.
Of course I kept a keen eye on the temperature gauge.
But I needn't have worried. The temperature remained rock steady in its usual position.
And a close inspection of the complete coolant system carried out this
afternoon showed no leaks and nothing wrong with the coolant level.
So hopefully there's no need to replace or recondition
the water pump. But I have made a mental note to use the car on a more regular
base in the time remaining for Club Triumph's 10 Countries Run in September.
But before that event there are two essential items that will be replaced. They
were dropped of at a friend's place for renovating, a few weeks ago because the
ones currently fitted to the car have rather worn spindles. As a result of
which they have become rather difficult to tune and synchronise. So time for a
shiny new set ...
