Internal and external anodizing of the tank ensures a long lasting finish. Internally welded fill and vent tubes provide a leak-free construction. The fill tube extends to the bottom of the reservoir to prevent air ingestion as coolant level expands and contracts. The vent tube exits through the bottom of the tank and can be routed out the bottom of your car with included silicone tubing. An integrated dip stick is anodized red and allows for quick reference of coolant level.\u003cbr\u003e\u003cbr\u003eThe main reservoir cap is a snug fitting injection molded plastic.
