Hey guys,

I've had my Hilux for 6-7 years now but still feel like a newbie. I've been driving my Hilux around town a lot this summer, but with the temps increasing I've been thinking about the radiator and coolant. Looking into the reservoir, it doesn't look low or anything, but I can't remember changing the coolant in the time I've had the vehicle...

Whats the best way to even tell if the radiator is working? Should I change the coolant? Any tips on doing this? Can't find much for these older Hillux's. I could send photos/videos if needed!

SOrry if this is a basic question, but I just worry about overheating on hot days like this!
