waynos 0 Posted January 13, 2011 i personally wouldnt put daz through my cooling system! however i have heard of people using a dishwasher to clean out the expansion tank Quote Share this post Link to post Share on other sites
carrots 1 Posted January 13, 2011 i think i will use the right kind of flush even tho a few people said to use it,also fairy liquid :shrug: Quote Share this post Link to post Share on other sites
fla 9 Posted January 13, 2011 use some baking soda - its caustic, hence alkaline so will remove the rust from the system. Dissolve it well in hot water then fill the system and curcualte for 15-20 mins. Do it after you've flushed the system thoroughly with water 5 or 6 times Quote Share this post Link to post Share on other sites
aki 0 Posted January 16, 2011 hi yep tried washing powder! just make sure its not going to foam up (washing up liquid is a no no!) dishwasher fluid may well work too! i even know of rover technicians using floor cleaner on k series! just make sure that you flush it all out afterwards a few times to make sure its all gone!! andy Quote Share this post Link to post Share on other sites

Henny 0 Posted January 17, 2011 I'd go one further as I wouldn't really class K-Series as engines to be honest... :norty: cleaning the expansion tank in a dishwasher works well... I've been advised not to do the cap by a mate who's a mechanic in the past, can't remember why though... :roll: Quote Share this post Link to post Share on other sites

Supercharged 2 Posted January 17, 2011 I wouldn't really class K series technicians as knowing much about engines tbh. they get pretty good at changing head gaskets though. LOL, not better than Henny surely?? As for Daz VW do a flushing agent and new expansion tanks are £15 - not going to break the bank is it! Quote Share this post Link to post Share on other sites
boost monkey 0 Posted January 17, 2011 The flushing agent is good stuff, comes in 2.5L square bottle (like an oil can) and isn't expensive. Whoever decided to put the thermostat in the coldest part of the cooling system on the K deserves a pat on the back :nuts: Quote Share this post Link to post Share on other sites
carrots 1 Posted January 19, 2011 i used surf in the end the liquid type,took the expansion tank off and used degreaser in it as its only a couple of months old.its also stopped my coolant light flashing all the time :clap: Quote Share this post Link to post Share on other sites
