IAG Coolant Overflow Cap
Part# IAG-ENG-5004BK / BL / RD / SL
Tools Required: None
Thank you for choosing IAG Performance. The billet
coolant overflow cap is designed to be a direct fit on the
OE Subaru overflow tank. CAD modeled and CNC
machined, this piece is designed to brighten your engine
bay and provide a strong and rigid replacement to the
stock cap that often deteriorates and distorts due to time
and age. The only assembly required is inserting the
rubber o-ring into the inner grove on the underside of the
cap.
Please follow the instructions below for an easy installation.
1. Place the o-ring into the grove and hold with your
thumb. With your other hand, carefully work the o-ring all
the way around the grove while holding it in place.
2. When the o-ring is almost completely sealed, it may
seem like it will not fit. Use both thumbs and press the o-
ring in until it is fully seated. It is designed to be a tight fit
so that it will not unseat when the cap is removed from
the tank.
