Coolant flush
16. Sep 2007 at 00:02

How many times do you think it needs emptying/refilling ??

Done it 5 times today, with a 5 mile run with heater on max hot ( Shocked

phew !!) between each empty/refill - and yes - it was left to cool down after each run !!

Still getting manky dark red/brown fluid in header tank and from radiator drain on each empty, runs clear after about 5 minutes of hosepipe action in through the header tank.

I intend to continue this tomorrow until it is clear after a run, is this wishful thinking ?? ... then top up with 50/50 mixture

Markjay Omega Lord Offline Posts: 5452 London Gender:	Re: Coolant flush Reply #6 - 16. Sep 2007 at 09:24 I do the following Drain, fill with water, warm-up engine, drain. Fill with water and 2 bottles of Holts regular rad flush, warm-up engine and run for 10 minutes, drain. Two more drain and fills. Last drain, them add 5L of Vx red antifreeze. This seem to work well, though the secret is repeating it every year.

Try the forte stuff - miles better than the holts rubbish on my tractor....

Sep 2007 at 14:59 All the petrol engines follow same procedure... ...the 2.5TD is different in that it has a block drain plug. The petrols don't have this, so you only get half of the coolant out with each drain.

im getting up early Tuesday morning and going to attemp the "coolant flush and re-fill"

IM SCARED !!!!!!!!! LOL

i dont have anyone with a VX Trade Card, how many big bottles do i need of this long life red coolant?
how much is it per bottle?
where can i buy FORTE stuff from guys?

also, do i need to use the hose pipe for a better flushing? or is that too complicated?
im gonna flush me car as many times as it takes to clear the blue mucky gunk out
i just use water from the tap on every re-fill?

cheers Thumbs Up!
