kingrat Posted January 18, 2010 Share Posted January 18, 2010 Hi, take off the bottom radiator hose, thats the quickest and best way to drain. Make sure the engine is cold, cos scalding hot water on hands and feet is very uncomfortable. Refill with pre mixed OAT antifreeze (the pretty pink stuff)will take around 10 litres due to residual amounts remaining in the block.

Aragorn Posted January 18, 2010 Share Posted January 18, 2010 I would use Concentrate antifreeze. That way you can put in 5L of the neat stuff, and then top off with water, to ensure the concentration doesnt get diluted down by the residuals in the block. Its probably cheaper doing it that way too! Quote Link to comment Share on other sites More sharing options...
kingrat Posted January 18, 2010 Share Posted January 18, 2010 the OAT antifreze is recommended for the TD5 engine as the blue stuff corrodes the internals over time. I know the blue stuff is for pennies compared, but just thought I would point it out. BTW Halfrauds had OAT on offer recently on a 3 4 2 but can't remember the price.

Aragorn Posted January 18, 2010 Share Posted January 18, 2010 I didnt mean not to use OAT, i just meant get the concentrated stuff, rather than the Pre-mix. Quote Link to comment Share on other sites More sharing options...
Andrew Chua Posted January 19, 2010 Share Posted January 19, 2010 open up lower screw on radiator hose. right side of vehicle (left side when facing the engine) open up the plastic bowl screw open up upper screw on radiator hose allow to drain tighten lower screw screw in upper (finger tight) top up coolant / antifreeze (depending where in the world you are) at the plastic bowl keep at it till you see some flowing out from the screw at the upper radiator hose. let some drain out tighten the upper screw (securely) start the engine top up the coolant at the plastic bowl again until correct level.

tweetyduck Posted January 19, 2010 Share Posted January 19, 2010 Just done this myself Drained the system and ran two big buckets of water through it before refilling used this antifreeze http://www.commaoil.com/productsguide/view/6/351 Motosave sell it in 5 litres. it didn't need the full 11 litres spec'd for my 300tdi. Yours should need 11.5 litres according to the web site. I reckon my drain wasn't 100% so i used 4 litres of Antifreeze and just topped up with tap water. The web site doesn't list this stuff for you vehicle but i can see no real reason why it wouldn't be OK its OAT stuff.

ajh Posted January 20, 2010 Share Posted January 20, 2010 There should also be a drain plug on the block you can use to properly drain the jacket. At least on the v8 there is a substantial amount in there. Personally I use PG coolant over OAT/Dexcool as it is non-toxic to animal life.
