Continental Engine Coolant Bypass Hose,HVAC Heater Hose P/N:65000
Route coolant cleanly through a tight 90-degree bend with the ContiTech Molded Heater Hose 63812, a universal 90° heater/coolant bypass hose that carries engine coolant between the engine and the heater core. Its pre-formed bend drops into cramped, hard-to-reach spaces without additional fittings or adapters, so it suits factory replacements, custom builds, and engine retrofits alike. It is cataloged as a fit for hundreds of vehicles, including the 2003-2007 Honda Accord [L4-2.4L], 2007-2014 Honda CR-V [L4-2.4L], 1996-2004 Acura RL [V6-3.5L], and 2004-2014 Acura TSX [L4-2.4L] — see the Buyer's Guide tab for the full list.
The hose measures 16 in long with a 0.625 in (5/8 in) inside diameter at both ends. Quantity used varies by application — many take one, while some (such as certain BMW models) call for more, so confirm the count for your engine. Country of origin: Mexico.
