Thank you!

 

how often should you do this?

 

Its in the owners manual.

Im doing it once a year, but Im wierd like that. I think its every 36K miles.

 

my friend gave me some of the water wetter from redline racing I noticed my fans on my Xa don't kick on half as much as they used to so maybe the stuff actually does work I was skeptical of it has anyone heard of a downside to this stuff. so far it seems to be working at least I don't have to hear my fans running constantly at idle.

 

Scions have super long life coolant, manual says like 90k or so
i DO NOT rec. to go that long
at least every 2years/24months (30k)

 

TRD also offers a thermostat that keeps the car cooler it's way overpriced but what does everyone think about them as the car is set up to run hot. the fans come on an awful lot I imagine this could affect engine life.
