Wooly,
I will start with the coolant level. We have engines that have seized because of slight coolant leaks from the valley mounted
fuel coolers. The valley holds
water and no coolant is noticed on the ground. The coolant bottle stays at the same level because it can't draw back into the radiator because of the leak. Radiator is difficult to check due to it not having a radiator cap.
They still get the
fuel coolers leaking due to our corrosive
water that gets in there from underground. Since fitting the low
water coolant alarms the problem has been solved.
One engine just failed and the vehicle was sent away and came back with a repaired engine from Toyota. No explanation was given as to what went wrong with it.
We have done some injectors but I don't know if it is
fuel related. I don't believe they need extra
fuel filters as it is just random injectors that fail. Although our
fuel is clean, all sorts of crap goes in when they are being filled + the odd bit of
water, so I believe the filters are doing their job.
All the best,
RA.
