Oil Pan Installation Note

WARNING: This page is about a different car, the 2014 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Completely clean and remove any oil, dirt, sealant or other foreign matter that may be adhering to the cylinder block and oil pan.
When reusing the oil pan installation bolts, clean any old sealant from the bolts.
CAUTION:
- Apply the silicon sealant in a single, unbroken line around the whole perimeter.
- To prevent silicone sealant from hardening, adhere the oil pan to the cylinder block within 10 min after silicone sealant is applied. Tighten the installation bolts completely soon after adhering.
- Using bolts with the old seal adhering could cause cracks in the cylinder block.
Apply silicone sealant to the oil pan along the inside of the bolt holes as shown in the figure.
