Myths and fairy tails about the VM TD

Do not obsruct airflow to the radiator. I know about the cool bars and aux lights in front of the radiator. They are an absolute nono!
Just have a look at the FSM. It is also mentioned in them.
They do not write it for fun!

What do you think about using white vinegar as a cooling system flush? I've seen it mentioned a couple of times on naxja... (i don't actually own a diesel, just curious in general...)

@davesta:
every sort of vinegar works- you need to leave it the coolant circuit over night. alloy may get a bit dull but that doesn't matter at all.
I used household cleaners with great success like antikal- they contain sulfur acid wich kills a lot of grime.
The heater is copper clean inside now. I let it in the coolant circuit over night-it does not work on the grease slime inside the engine. But drano works good there, hehehe

@murray:
You just convinced me to use that CAT stuff.
If it works in their engines it will work in our diesels too!
The data sheet has remarkable abilities and it does contain already deionized water.

I tought about Evans waterless coolant, but what to do if you need to refill while travelling?
I just have to find out were to get CAT elc...
CAT engines are designed to give fullpower all day long-so it must be good stuff.

Just found out, it is designed for wet sleeve cylinder liners.
That the absolute right stuff for our engines! Good find, Murray!
Do you work with CAT equipment?

Cool Murray, thank you very much for the info. I bet you know about your job and I won't go cheap here.
It is essential to have the best affordable coolant! No doubt about that. and I'm sure Australia can get a bit sunny!!!

I just replaced my thermostat, it had the worn scratch marks in the wax chamber again. I don't waste my heads for a 9 € thermostat.

It took a lot of scrubbing to getrid of at least the visible dirt inside the engine.
A rifle bore cleaner and several bottle cleaners are good to use for that. Chemicals alone are always difficult. they simply can't replace a good brush.
So a good coolant is very important. And access to a better one is extremly valuable.
