Gates Radiator Cap 16 psi
Product description
If you need a replacement radiator cap, the first question is whether its pressure rating and cap style match your cooling system. This Gates cap is listed for open or closed systems, but that alone doesn’t confirm fitment for a particular vehicle.
Its stated rating is 16 psi, with an SAE range of 14–18 psi. That gives you a concrete starting point when comparing it with the cap you’re replacing.
The cap also has a safety-release design and corrosion-resistant, heavy-gauge metal construction. The tradeoff: the product details don’t provide vehicle-specific fitment or dimensions.

How to use it
Treat this as a replacement part to match against your existing setup, not as a universal cap. Before ordering, compare the pressure rating and cap style specified for your radiator with the information available for this part. The included replacement references—7916, 10333, 11333, 33065, 46066, ST-16R, 70333BL, 70333RD, and 703-1394—may help identify whether it corresponds to the cap you need.


A practical check is to look at the markings on the old cap and your vehicle’s service information before removing it. If both point to a 16 psi cap and the listed replacement references match, this Gates part is more relevant than choosing a cap by appearance alone. Work only on a cool cooling system, the release feature does not make it safe to open a hot radiator.

Pros
- Rated at 16 psi, with a stated SAE range of 14–18 psi.
- Listed for applications with or without a coolant recovery system.
- Safety-release design and corrosion-resistant, heavy-gauge metal construction.
- Multiple replacement part numbers are provided for cross-checking.
The range is useful context, but it isn’t a substitute for matching the required rating. A cap that looks similar can still be the wrong choice if the pressure specification or fit differs.

Spec sheet

Gates describes this as an OE-grade replacement radiator cap with a safety-release design. It is identified as a mini cap for open or closed systems and has a 16 psi rating, with an SAE range of 14–18 psi. Its construction is described as corrosion-resistant, heavy-gauge metal. The product information says it covers a wide range of pressures, but does not give dimensions or a vehicle application list.
On the spec sheet, the useful buying details are the pressure rating, system type, and replacement references. There is no stated vehicle compatibility chart here, so don’t treat the part-number list as proof of fit for every vehicle.
When it makes sense
It’s a great fit if you have a clear replacement reference or have confirmed that your application calls for this cap’s pressure rating and style. For example, comparing the old cap’s markings with the listed numbers before a repair can help narrow the choice without relying on appearance alone. The safety-release design and metal construction are relevant features, but the details don’t establish performance beyond what is stated.
It may not suit you if you need confirmed fitment for a specific vehicle and can’t verify it from the replacement numbers or your vehicle’s service information. In that case, a cap listed explicitly for your vehicle is the more dependable route. Choose this Gates option when the rating and part reference line up, keep looking if either remains uncertain.
