[xk] coolent filter

XK

I was watching some of the Jay Leno videos last night, now there is one
serious car nut.
One of the videos was about filtering the cooling system. He had a screen
which fit
into the coolent supply which caught the trash in the system. My first
thought was this was a good idea. Then I wondered, is it really a problem
that the coolent
system needs to be filtered? Anyone have thoughts on if there is trash in
the coolent system?

As always, enjoy the discussions.

Neil,

IMHO,
Not in a small closed system! If some how a heat exchanger was shared
between multi engines, then perhaps it would limit clogging to the good
ones should one of the others go sour.

It also might be fine in direct water cooling but then you’d need a lot
of hose…

Seriously, I would seek where the “trash” comes from and eliminate it
instead of “trapping it downstream”. Even if you are forced to add
coolant gleaned from the side of the road, you’d be better served to
strain it through your socks and shorts than rely on a screen in the
system somewhere.

Just as in the oil filter system there is a bypass provision, there properly
should be one in a water filtration/strainer if crud were a real problem.
Complexity for no tangible gain.

The local service station sold a ‘sock’ which one puts in the top
radiator hose.

Considering the age of our engines there is no end of rubbish
inside the cooling system
Blocks and heads should be thoroughly tanked before a rebuild, but
I suspect many people don’t.
Even after that one can dig inside the galleries where the core
plugs have been removed and try and loosen the really hard stuff.
I have often found wire from the reinforcing in the orignal sand
cores from manufacturing.

And if you’ve had a new radiator core or it just cleaned it out
you don’t want that clogging it up again.

So the last one I did , I put a sock in the hose and removed it
after about 1,000 miles and it was full of rubbish.
I would definitely use one. It’s cheap and there’s no down side.–

Ed,

Glad to hear you are using ‘‘safe cooling’’.

There is a product in the US at around $US72.

The sock sounds simpler and less obtrusive for the purists.

Regards

This is pretty common on large trucks… Not a bad idea. Best though to
frequently check the acid level in the coolant.
