1985 PT-40 Radiator Question

[curlesw]

Thanks Pete.

The hose ran from the pump into the engine block....fairly easy to
reach. It had a 2.5" rip in it...didn't expect such a huge failure.
Sure, maybe a small hole from a 21 year old hose, but wow! I lost a
lot of fluid very quickly. I'm glad the engine alarm worked since it
was at night and I could not see all the smoke pouring out the back.

I did not noticed the surge tank and site glass...will have to look
for that when I add coolant back into the system to ensure I do not
overflow.

I read the BB manual and it said to use an antifreeze which contains
ethylene glycol. When I get back home I'll have a complete flush of
all fluids anyway, it's time for a complete refresh...just need to
get home by Sunday, which is 2,000 miles away!
