Hi all, I need to top up my coolant, I've got the green stuff already in there, anyone know where i can get some?

I'm working till late everyday this week so anywhere open till about 8pm would be preferred. I'm based in west London. Does Halfords do it?

Also do I need to dilute the liquid? Thanks in advance and apologies for the absolute noob questions!

 

halfords should have it. It should be mixed 50/50 with water. But if your topping up and dont know what the dilution is in there i'd top it up with the neat stuff just to make sure its strong enough.
