Manufactured from quality plastic, the reservoir's thick walls are engineered to withstand heat and vibration, with three mounting holes for maximum flexibility for installations where space is tight. It comes complete with a vented cap.

Review: Awesome small package of a coolant reservoir - Did an engine swap and could no longer use factory coolant reservoir and the tracks require an actual reservoir not just a water bottle or anything so this works perfectly. It’s not pressurized so don’t expect it to work like that just simply a reservoir.

## Questions & Answers

**Q: what is the capacity of this reservoir bottle?**
A: Assuming to the listed exterior dimensions are correct (7.5x8.25x4.25 inches), the volume is roughly 260 cubic inches. A gallon is 230 cubic inches, so subtracting a few pennies for container thickness and rounded corners, it should still hold near 1 gallon.

**Q: What is the distance between the two screw holes at the top?**
A: Mine appears to be 4 inches center to center, but I can see there can be some manufacturing variations (+/- 1/8").  As another reviewer pointed out, the holes are offset towards the outside of the tabs by about 3/16" from the center of each tab.

**Q: Does it come with a cap? Photo does not show one.**
A: Mine did in fact come with a vented cap.

**Q: What size hose (ID - Inside Diameter) do you use for the fitting at the bottom?**
A: I used the same hose that was in the Lexus since it was in good condition, I don't know the diameter.  I just cut of about 1/2" off to make sure of a good fit and contact.
