Coolant type

[Mr DJC]

Hi,

So I need to top up my coolant on my LS460. It’s not leaking at all but need topping up. Am I best to drain it and refill it or just top it up with the recommended coolant.

Thinking.     When was the radiator last changed ?

10yrs / 100k miles might apply

It hasn’t been changed. It is on the to do list but for now I just want to top the coolant up. Problem is I don’t know what coolant is in it now so need to find out really.

It should be Toyota pink coolant (Super Long Life), you can buy pre mixed 1ltr bottles from dealers, to be completely sure look in your manual.

Here you go

well, if the radiator changeover is going to be prior to the onset of next winter then I would think maybe a simple top-up with distilled water might be ok  . you're not going to worry about it's deep cold / freeze preventative measures ........unless the changeover isn't really on that short horizon   🙃
