Jspec Germany Posted January 4, 2006 Share Posted January 4, 2006 I hate to post without concrete info and am sure I'll be showered with criticism from Jake or Ian, but... I've heard that it's better to use distilled water rather than tap, eliminates the deposits. I'll also be doing a full flush soon and will include a bottle of water-wetter.

Yes the purer the water the better....as it's only animals and us that need crap in their water This is why I get 4Life Red from Toyota, it's already well filtered/distilled and premixed!

n00b Posted January 4, 2006 Share Posted January 4, 2006 i did mine last weekend and i got 2 5litre red coolant from mr t and was left with around 1-2 litre after top ups etc.... (£36 or there abouts) i drained the system then filled with tap water, ran for around 15 mins (topping up all the time (i was testing heating)) then drained that and filled with the red toyota coolant... theres a good trick here Car cold,take the rad cap off and start the car, switch the blower on to full and heater onto full, get yourself a nice big jug for adding the water into the rad. keep the car running at a fast idle and eventually the thermostat will open and thats when the water will be cicurlating fully, you will start to get bubbles (this is AIR) coming outta the top of the rad just keep adding water in and eventually you will remove the airlock. it takes a while to get the airlock out,keep checking the heat from the airvents and they will eventually go very hot. And be careful as doing this can get you a nasty burn. Replace rad cap and check expansion tank and take car for a run and check levels later . from this post http://www.mkivsupra.net/vbb/showthread.php?t=54779&highlight=heater+matrix the guy who wrote it was bedlam good luck n00b Quote Link to comment Share on other sites More sharing options...

I have 50l of de-ionised water for the task. Cheers for the help everyone, Holts/Radweld flush it is. Quote Link to comment Share on other sites More sharing options...
Ric Posted July 24, 2006 Share Posted July 24, 2006 if your using toyota 4life coolant isnt this ready mixed? so you wont need any water Only for the flush so you dont really neeed to use distilled just for a flush? Quote Link to comment Share on other sites More sharing options...
Scooter Posted July 24, 2006 Share Posted July 24, 2006 Only for the flush so you dont really neeed to use distilled just for a flush? i agree....its over kill. Over a long time the ions in normal tap water could give you problems but for flushing i wouldn't bother, or at the most i'd do the last flush with de-ionised stuff.............. The filling of the system with plain water (ionised or deionised) and running seems like a good idea, but also a hose pipe (obviously not available to all at present) flush will possibly remove more solids as it will give more flow than just draining the coolant/water.

JohnA Posted July 25, 2006 Share Posted July 25, 2006 I'd *never* use tap water in the cooling system, not with the limescale levels of England. Even for a good flush, I only use non-tap water (filtered rainwater in my case). At least a couple of litres of coolant will remain in the block if you don't use the second drain bolt (a bitch to access) Quote Link to comment Share on other sites More sharing options...
