Realised on a long journey "farn sarf" that my climate control doesn't provide much heat, it's lukewarm at best. After ignoring the missus going on about "there's cold air hitting me again" for a few weeks, I finally realised she was right....but don't tell her.
I want to try flushing the heater core but I have two questions:
1) Halfords sell a VW 5ltr bottle of coolant, how much coolant is required from empty? Do I need that much or can I get some VW stuff off ebay in 1.5ltr bottles?
2) Where is the easiest place to get the required hose. It looks like I need 20mm/21mm or 22mm diameter hose but clearly don't want to buy an entire reel for 50 quid?
