Thermostat Installation Note
WARNING: This page is about a different car, the 2016 Mazda CX-3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- Do not apply oil (such as engine oil, ATF) to the rubber seal part of the thermostat. Otherwise, the O-ring could swell causing a seal malfunction.
- Install the thermostat with the jiggle pin aligned with the notch of the water outlet.
