Which coolant

[dfen5]

Got a '98 Rav4 I've just done the timing belt / water pump on. Coolant drained was blue. Looks like the shops recommend the pink/red stuff (OAT?).

There's some horror stories about mixing coolant types - what to do?

Was thinking that but just had a better look at the old stuff - it's purple so it's been mixed already. Going to flush it and put the newer pink but thanks anyway.
