Hi All,

I'm going to change the coolant this weekend on my '03 WRX PPP. I've heard that they need special coolant, any advice for which is best?

Also do you need to use the coolant conditioner?

I'm going to drain the coolant and refill with water to flush it round, then drain again and refill with the correct 50/50 mix.

I've read about the filling procedure to ensure that all the air is removed from the system and i'm fairly sure I can manage that (I'm used to BMW's which can also be a complete pain in the ****).

Many Thanks,

 

Go to a reliable auto-factors (so not Halfords etc), and buy anti-freeze suitable for an alloy engine and with corrosion inhibitor. They will know what you need.

Coolant conditioner can't hurt, but isn't really necessary with modern anti-freeze.

 

If you live somewhere with hard water (i.e. your kettle fills with crusty shyte), then see if you can find someone who uses a dehumidifier in theyre conservatory etc. That waters the shizzle.

 

Changed it today, easy as pie, don't know what all the fuss is about!!

Longest part is waiting for the system to drain itself!
