PRODUCT DETAILS
Honda Integra / CR-V Coolant Expansion Tank Cap & Elbow – OEM (Part #19102-PM5-A00 / 19106-PA0-020)
This Honda Integra coolant cap and OEM Honda coolant elbow are what your overflow system should’ve had from day one: fresh, tight, and not baked to death from 25+ years of heat cycles. The Honda 19102-PM5-A00 cap and Honda coolant elbow 19106-PA0-020 are genuine OEM pieces that restore proper function to your coolant expansion tank, so the system can actually move coolant in and out of the reservoir the way Honda intended.
The cap is a direct fit for the Honda coolant expansion tank part number 19101-P72-000, used on the DC Integra and RD1 CR-V applications. If your Acura Integra coolant cap or Honda CR-V coolant elbow is original, there’s a good chance the plastic is chalky, cracked, or barely sealing anymore. That’s how you end up with slow leaks, crusty tanks, and “mystery” coolant loss. Swapping to fresh Integra CR-V coolant parts straight from Honda means the tank can actually hold pressure and work with the radiator cap instead of against it.
Both the OEM coolant tank cap and the elbow are sold separately, so double-check what’s missing or damaged on your car before you order. If you’re piecing together a used tank, you’ll usually need both the Integra coolant overflow cap and the elbow to finish the job. These are Honda factory parts, so you get the original fit, proper hose connection, and a clean install on everything from a daily-driven 1997 Honda CR-V cap replacement to a mint 2001 Integra build. We still run these exact parts on our own cars because aftermarket caps and elbows are hit or miss.
*Pieces are sold individually. This is not a bundle for both items. Please purchase the elbow AND the cap if you need both.
