This listing includes 4 Old School Heater Core & Water Pump Block Off Plugs (correct, as pictured). These are used to bypass the heater core or Water Pump due to leaks or excessive heat inside the car. This listing includes 2 of each size!

If your car ever has a leak from the heater core, then these are used to bypass the heater core and get you back home ..or just bypass the heater core during the summer so the air conditioner can cool easier!

One way to tell if the core is leaking ..steam will rise up on the lower inside windshield after the engine heats up or is driven a while. The passenger floor board (carpet) can also feel wet.
