Dayton Parts 603-5103 COOLANT RESERVOIR-NAVISTAR/IHC

Heavy Duty Pressurized Coolant Reservoir

The original coolant reservoir on certain International vehicles fails when the level indicator leaks. This Dorman OE FIX solution is made of entirely clear plastic to remove that failure point.

• Improved design - this replacement heavy duty coolant reservoir removes a common failure point in the original equipment design
• Simple fix - clear plastic instead of original black plastic eliminates need for leak-prone level indicator to gauge fluid levels
• Durable materials - proprietary polymer resists cracking from extreme temperatures
• Application specific - made to directly replace the pressurized coolant reservoir on certain International models
