Raven Posted June 19, 2011 Report Posted June 19, 2011 LOL, C & C Radiators. He's the rudest customer out of all our customers at work. I've had experience with Motor Radiators in the city on Halifax Street, one of our best customers and their quality of work is pretty awesome. Give him a try! Quote
love ke70 Posted June 19, 2011 Report Posted June 19, 2011 coolant doesnt stop chlorine reacting with aluminium but coolant will provide a layer of protection usually in the form of a corrosion inhibitor, generally a silicate (silica based) material. Premixed coolants are just coolant ( and demineralised/de ionised water - so either buy demineralised water or leave your tap water out over night - the chlorine will evaporate quite quickly - either that or boil it - i just leave my water out over night if i need do any cooling system work - that way the protective layer the coolant provides wont be eaten away by the eventual formation of acid caused be using straight tap water with chlorine ..... but then again we are talking about pretty long term slowly developing issues i guess .... MMM like my radiator developing a leak where the tubes join the end plate you mean :P didnt know about leaving it over night. would leaving it in the sun be better, as the sun 'kills' the chlorine? might have to fill a couple of buckets lol what do you do to flush the block etc? as even when you take the drain out of the block some gets left behind....

philbey Posted June 20, 2011 Report Posted June 20, 2011 the less weight it has the better it will cool. silver is the best thermal conductor of all and its much heavier than aluminium - next best is copper and then brass, then aluminium. the reason that aluminium is used now days is first of all it is cheaper and secondly the lead based solders used to join up our old radiators where found to be a health hazard in the manufacturing process. Lead is a very poor heat conductor as well, so basically performance of copper/brass or aluminium radiators (based just on the material used) is very similar ........ :yes: maybe based solely on material used it might be similar, but I can assure you, a triple core copper/brass rad in a patrol will only be marginally better than a standard twin core aluminium/plastic one, and yes, thats 45mm vs 32 but then theres ebay complete double core aluminium ones that are thicker than the standard ones and don't cool anywhere near aswell, so maybe it comes down to construction as much as materials not trying to start a shit fight, just my belief and a number of peoples experiences. Yeh no point arguing. Weight affects how much heat energy the metal absorbs. Thermal conductivity determines how fast heat travels through the metal, and isn't affected by weight, but rather the thickness of the metal. With intercoolers, the weight/heat absorption thing would be critical for heat soak, copper intercoolers would suck because the copper would be able to absorb more heat than aluminium.

I know you don't like him Mick, but I thought he was pretty good. having said that, the guys on Halifax street lay some welds on my trashed rims and they were really good to deal with. Quote
