My tC has approximately 124k miles on it so I'll be doing a coolant drain and refill pretty soon. In the process I'll be installing a new Koyorad radiator along with new hoses.


While I'm at it, should I replace the OEM thermostat too? There's nothing wrong with my current thermostat, but I'd like to be proactive and replace things before they become a problem.


I've search around, but couldn't find what's the average lifespan of a stock thermostat and when it should usually be replaced.


Any help would be appreciated. Thanks.

 

Knowing me i would. I replace all my parts with aftermarket performance stuff as it breaks. So that being said go with a mishimoto to complement your koyo rad
