Dear Tom,
Good p.m. For how long have the French hoses been in place? I'm wondering if that ridge is a manufacturing defect, that compromises long-term serviceability.
Thanks for the "heads-up" about the hose ports on the firewall. I will use an
X-acto knife carefully to cut the rubber paralell with the copper tube's axis. I may make two cuts about 30 degress apart, so that the hose will come free easily. Those ports are relatively accessible, so that should not be a problem.
I'd like to flush the cooling system. What is the proper sequence?
For example, should one:
(a) drain the coolant by opening the drain cock
(b) re-fill with water
(c) let the engine get to operating temp (so get clear water to the heater core)
(d) let the engine cool
(e) drain the clear water (dirtied by what's inside the heater core)
(f) close the drain cock
(g) change the hoses
(h) re-fill with coolant/water (50/50mix)?
Some further questions:
(a) Can dishwashing liquid be used as a hose installation lubricant?
(b) Is the head hose port stronger than those on the firewall?
(c) Must one cut the hose length-wise, to detach it from the head hose port?
(d) Can one grip the hose and pull it free of the head hose port?
I'd hate to snap the hose port from the side of the head!
Thanks for your insights.
Yours faithfully,
spook
