Hey folks. I about to change the thermostat on my 2001 Toyota Sequoia so figured I’d do a coolant drain and fill while I’m at it. I looked thru my records and can’t find if I used OEM or aftermarket coolant the last time. The dealer says the new pink stuff replaced the red and that I’d need two gallons for a radiator drain and fill. Well, that’s about $65 bucks for OEM. If I need it, I’ll get it but I wondered if any of the OTC brands are good quality? Valvoline maybe? Thank you.
