bear101 Posted February 28, 2021 Share Posted February 28, 2021 Morning guys. I have just bought a 2005 3.0rn and while I had the undertray off I noticed the front oil cooler water pipe that goes to the oil filter was leaking . Do I need to drain all the coolant to change the pipe as it is at the lowest point of the coolant system . And do I do that by undoing the bottom hose ? What coolant do you recommend I use as the one in the system is a greeny /yellow colour. I've been looking for a good 2005 one for a while because of the cheaper road tax . Not a good start .

Dr. Acula Posted February 28, 2021 Share Posted February 28, 2021 Re: antifreeze, I've just learned that OAT (organic acid technology) is the recommended one for my 2007 Forester. 1 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 28, 2021 Share Posted February 28, 2021 I don't have much experience with the 3ltr but I've always drained ej20's via the bottom hose . Colour of anti freeze isn't necessarily the best way to determine what to refill it with . I personally use motul ingul premixed anti freeze (around £40 from as performance) but as long as you use a antifreeze suitable for aluminium blocks (oat) you'll be fine . On the ej20 /ej25 you can buy a oil cooler hose kit , that comes with the 3 silicone hoses and hard pipe that crosses the front of the engine to the waterpump . unsure if the 3ltr has exactly the same set up but worth changing it all if your draining the coolant imo Quote Link to comment Share on other sites More sharing options...
