We were going to replace or at least inspect the impeller and loosened the cap for it.
We took the TS out and gave it to Jonco Marine who was at
the Marina Puerto de la Navidad(Barra Marina) doing some chain plate work on a boat. Jonco
tested the TS and cleaned it. We got it back the next day. He said it tested to
be OK so it is the o-rings. They are still good but they did not seal. So
operator error – again. This time I will try a little different approach.
Centering the TS then evenly tighten the bolts.
The good thing is the
TS got a good cleaning which I was not able to do. I have cleaned the TS and
end caps up with 220 sand paper this time I was a bit timid to be so aggressive
with the cleaning before. Next will be the heat exchanger flanges then a re-assembly.
Of course we had to remove all the antifreeze we could from
the system. Also we re-routed a heater hose removing a loop and getting it away
from two fresh water hoses it was touching, possibly heating the water up. The
hose from the engine to the water heater.
Aside from that and scraping the water line water got cold
we have been hanging out t the Barra-Bahia de Navidad pool and Debbie is
working on getting well. We have two pool cards now as a friend let us use them
and we get the use of the hot showers and pool with towels etc. We just dinged over and have pool day Not a bad way to
spend the day!
We did take a trip to Manzanillo by bus but that is another
story.
Based on what you were saying about the coolant in the raw water pump, my guess was the tube stack was OK. We had a leak in the tube stack of our Pathfinder once, but in our case raw water was in the coolant side of the circuit. The pressure of the raw water pump is greater than the engine coolant side when the engine is running, so raw water gets forced into the coolant side raising the level of the coolant to over flowing. The Pathfinder tube stack has to be centered 'exactly' inside the heat exchanger, and if it's not one of the end boots will allow mixing of the raw water and coolant. My guess is if the end cap or boot is not sealing correctly coolant will actually be drawn out of the engine, lowering the level of the coolant not raising it like a hole in the tube stack would cause. Do you remember if your coolant level was lower?
