Product Details

The Gates 31539 is an OE-type radiator cap designed for closed cooling systems with threaded coolant bottles. This high-quality replacement cap maintains proper cooling system pressure at 17 PSI (within the SAE standard range of 15-18 PSI), ensuring optimal engine operating temperature and preventing coolant loss.

Key Features:

  • 17 PSI pressure rating for consistent cooling system performance
  • Threaded design for secure installation on coolant bottle applications
  • OE-type replacement ensures proper fit and function
  • Engineered to meet or exceed original equipment specifications
  • Helps prevent overheating and coolant evaporation

Gates radiator caps are precision-engineered to maintain the correct pressure balance in your cooling system. The proper pressure rating raises the boiling point of coolant, improving cooling efficiency and protecting your engine from overheating damage. This threaded bottle cap design is commonly found on modern vehicles with pressurized coolant recovery systems.

Quick and easy

They had the lowest price and great communication. Will order from them again thanks

For as cheap as what I paid for my product I will admit I was scared!!! Got what I asked for in perfect condition, came fast and wonder where have you been all my shopping life? Thanx for such a great deal and fast shipping!!!

Incredible prices! I purchased a name brand leveling kit for 40% less than any one else is selling them for. Item shipped out within 2 days. Shipping cost is reasonable, and if you leave a review here after your purchase, they'll credit you back $5! BEST DEAL GOING!

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Good

Unbeleiveable!!!! Super fast shipping!! Great job!!! Keep up the good work!<br><br>P Savaria
