without wanting to sound silly...How do I change the cars coolant?
The coolant in header tank is a horrible brown rusty colour and having only had the car a short time I don't know when it was last changed.
I am no mechanic, So even something like this seems a bit daunting to me. Is it something I can do easily myself? Or should I just take it to a professional to get it done?
If it is a simple enough job, could someone just let me know what I need to do...
Cheers!
