WHY TO BUY?
The radiator cap plays a crucial role in your cooling system. Its job is to make sure the cooling system stays pressurized, but if it achieves too much pressure the cap bleeds off coolant and air so that other crucial components do not fail. Over time factory Toyota Sienna radiator caps break due to the extreme temperatures which they are subject to. Here at Andy's Auto Sport we have a complete offering of replacement Toyota Sienna radiator caps to keep your cooling system working properly and give you added piece of mind as you drive down the road. A new Toyota Sienna radiator cap is cheap insurance to avoid other expensive cooling system problems.

DID YOU KNOW?
Radiator caps come in different pressure ratings depending on the vehicle. However if you run a high-performance aftermarket radiator and aftermarket hoses, it is often possible to upgrade to a higher pressure cap. This will allow the cooling system to operate at slightly increased pressures which will keep coolant circulating through the motor when things get hot. In addition to being a functional part of the cooling system, aftermarket Toyota Sienna radiator caps also provide a shiny new look that will keep your engine bay looking clean. Available in different custom designs, radiator caps can help your ride stand apart from the crowd at the next show and shine.
FAQs
Q: Why buy a radiator cap?
A: With a high horsepower motor that sees the track often, you'll need a high-pressure radiator cap. With a higher pressure rating it raises the boiling point of the coolant

Q: How do you install a radiator cap?
A: Radiator caps are installed in seconds by removing your factory cap and replacing it with a high-pressure unit.
