Spot on with the coolant. Good idea to burp your baby :P what's burping the system mean ? Bleeding the system of air. champion! i'll do that tomorrow, hopefully toyota have some in stock :) also i heard from someone that toyota long life coolant (red) isn't too friendly on rubber... he said that ford used to use red coolant until it did the same thing and they changed to the green coolant. he said the dye is the culprit. how accurate is this i wonder? full of s**t. The toyota red coolant is awesome. Remember when you remove that plug it will basically drain your whole radiator, so be prepared for that and you'll also have to refill and burp the system afterwoods. can i plug the holes with my fingers while my wife changes the o-ring on the tap? LOL also can i drain the fluid in icecream containers and use it again? of course the fluid must not be contaminated You can try, but you will still lose some.
