Title: Heator Hose Connection
Post by: altuschevy86 on January 23, 2013, 12:31:58 pm

Installed heater core on 86 Chevy C10 that wasn't connected, need instructions on where to connect heater hose, to the engine block or water pump.

Take a look at this example... Illustration of heater hose routing (http://forum.73-87chevytrucks.com/smforum/index.php/topic,24919.msg207967.html#msg207967)
If you don't have the heater hose connection to the radiator, the 3/4" hose will connect to a fitting threaded into the top of the water pump.  The 5/8" hose connects to an intake manifold fitting located either at the right front or right rear, depending on model configuration.
