My Raw Water
cooled Volvo Penta
2003 has been overheating
. I am replacing the Exhaust
of the, (is it brass), distribution pipe which runs through the engine
block I discovered it was clogged up and only has a small 2mm diameter hole at the inlet end.
I also lifted the thermostat housing and found white gunk everywhere, but the area was relatively clear compared to the cooling
tube. I know the thermostat works because a calorifier
is in the circuit and this and that heats up.
To my questions:
Is it possible to remove this tube for cleaning
? Or should I try and descale it in place by pumping a descaler such as Rydlyme through it?
Should I be pumping decaler through the engine
block as a whole? Where is the best point to exit the descaler? (I have an anode I will have to remove and plug
up, is this a good place to attach the return hose?) Or is their a better place?
Thanks very much.
