So it wouldn’t be a holiday without a couple of mechanical bits of joy!
Noticed that the coolant in the reservoir attached to the Universal 5432 was down about 40% one morning; I usually keep it just below the overflow level. Topped it up, adding about 0.75 litre/quart and motored away; after about 4-5 hours of engine running, same issue – no visible signs of leaks; oil was clean and dark; engine temp was right where it should be (+/- 178F); Checked the engine coolant loop - hot water tank and bus heater – no leaks & hot water doesn’t taste like coolant.
This scenario has been repeated for about a week.
The only thing that I can think of is that the heat exchanger must have an internal leak, letting coolant escape to the raw-water side. Does this make sense? Is there any other place it might be escaping to? Would greatly appreciate any thoughts, comments or recommendations!
