Mustang Coolant Overflow Bottle - Tech Inspection
Canton Aluminum Coolant Reservoir
With age comes weakness. While it could be construed I'm referring to Publisher Shiver, in reality I'm talking about plastic products. It's no secret that automakers use lightweight products-mostly plastic but also aluminum and other materials-to save vehicle weight. Doing so increases performance and fuel economy, provides better handling, and can even mean easier servicing. For more than two decades, Ford has used plastic on Mustang interior parts and trim items. But the use of plastic reaches under the hood as well, where many new cars have plastic valve covers, timing covers, and so on.
Mustangs have had plastic coolant reservoirs since the late '60s. It's only a matter of time before your car's reservoir will fail from heat cycling and contact with coolant and other chemicals. Sure, you could buy another plastic replacement bottle-and watch it turn yellow and brittle, only to be replaced again down the road. But for a few bucks more, you can purchase a Canton aluminum reservoir that will last a lifetime, look ultratrick under the hood, and-best of all-bolt right in without a single modification (why can't all "bolt-on" parts work like this?). Check it out as we install one on Associate Editor Johnson's new and as-yet-unnamed '89 notch project.
