OEM Toyota Water Valves Vs. Aftermarket: Who Wins?
When it’s time to replace your vehicle's water valve (tutorial here), you might be wondering which type of replacement part offers the best value and quality. We can answer that question for you: OEM Toyota water valves definitely come out on top. Here’s why:

1. More Fidelity
OEM sensors have more fidelity, as they're manufactured to exacting Toyota specifications. Most aftermarket water valve sensors are 'universal,' and as a result they don't always work as well or as consistently as OEM sensors.
2. Tighter Tolerances
Not only are OEM water valves and water valve sensors manufactured to OEM specifications, but they are also manufactured to tighter tolerances. That makes them both easier to install and less likely to leak. You can’t say the same about all aftermarket water valves.
3. Manufacturer Warranty
OEM water valves and water valve sensors are backed by the Toyota parts warranty, which is a fair and comprehensive policy. Many aftermarket water valves don’t even come with a warranty, and the ones that do aren’t covered by a policy that’s as good as Toyota’s.
4. Better Grade Materials
OEM parts in general use better grade materials. A lot of cheap aftermarket parts cut costs by using inferior materials. OEM Toyota water valves are made of durable materials that are designed to withstand the corrosive effects of older coolant, which can be substantial. While no part can survive a cooling system that isn't properly maintained, these valves are built to last a long time.
While an OEM water valve may cost a little more than an aftermarket water valve, you’ll end up saving a lot of money in the long run, thanks to its incredible quality, fidelity, tolerances, and Toyota’s parts warranty policy.
Not to mention, when you buy OEM parts online, you save big. For OEM Toyota parts, for example, our pricing is much better than your local dealership.
A cheap aftermarket water valve is more likely to malfunction and cause radiator problems and engine damage, so we strongly recommend replacing your water valve with an OEM Toyota water valve (part no. 16670-21010).
