Rear Coolant Pipe – D16Y7/Y8 (96–00 Civic) w/ Yellow Zinc Thermostat Bolts

This replacement rear coolant pipe is a must-have for any D16Y7 or D16Y8 engine found in 1996–2000 Honda Civics. Located at the back of the engine block, it connects the thermostat housing to the water pump, directing coolant through the system and ensuring proper engine cooling.

Over time, factory pipes corrode or leak — especially during rebuilds or after head work. This OE-style metal pipe restores proper function and durability, and includes a set of yellow zinc-coated thermostat housing bolts to replace old hardware and a fresh set of  O-rings to a secure seal.

Ideal for engine swaps, maintenance, or full builds, this is one of those essential pieces that helps keep your cooling system tight and reliable.
