Today my 605 decided to leak some coolant and it has no heat. The engine is getting up to temp, last year i replaced the thermostat and coolant also flush the cooling system, but the coolant again looks like dirt, this engine has incredibly high mileage so the engine block must be full dirt. I pressure tested the entire system up to 1,5 bar and there was no leaks, not sure where the coolant come from but i proceeded to fix the heater. First i drain the coolant and its awful, then had to take off the upper intake and couple of the boost pipes. Then i hooked up my 3/4" garden hoses from the tap and the other to drain in bucket, i flashed it in both direction and use some oven degreaser. Put it together and now i have much better heat. This car has surve me very well but it's getting near its end i plan to get it registered for 2022 as well but if there is any big bills i'll park it.
