DEX-COOL

I have a 2009 C6 and need to top up the coolant

The manual says to use DEX-COOL

This seems hard to buy in the UK

Does anyone know of a UK supplier or a GM-approved alternative? (I am in south London)

Many thanks!

Late response to this thread, but Covid-19 does have that effect. I had to top up my coolant on my previous C5 and sourced some DEX-COOL from Keith at Eurovettes, posted straight to my door. Think the general advice is NOT to supplement your coolant with anything else - cheers!
