Formed heater hoses
« on: May 07, 2016, 09:05:40 PM »
Looking for the two sizes of the heater hoses, 5/8th and 3/4quarter inch hoses for my 62with a/c. As these where molded or formed in a 90degree angle. Do to the tight space behind valve cover and fire wall where the inlet and outlets are for the heater core.

just go to any parts store and ask to look up heater hoses in a book ,tell them what you are after
I think they come in 24 and 36'' long pieces and the longer ones were cheaper
they fit  real nice and connect up to behind water pump in one piece from heater core


just looked up on yahoo search
dayco # 80405 for 36''  5/8 and 80416 for 3/4 x 36''

Thanks for the hose numbers! As this was a great help,just left the parts store w/ both hoses, they had to cross reference the number to a gates # from the dayco #. Easy on the wallet also, out the door for 28 bucks!

I have a similar question regarding heater hoses.  Either my heater core or 90 degree molded hose ruptured on 57.  I see there is a gates 5/8" hose with a 180 degree bend which I think might work to reroute coolant back into the pump.  Anyone care to give some input if this would work?

to bypass the heater core yes it would work
but so would a hose coupling to connect hoses together will work

Maybe the ’57 is different, but on my ’58 both hoses are ¾”.   

Its easy to just to cut off a 2ft or so length of regular hose and route it back to the water pump as a bypass.   I would guess the water doesn’t need to circulate much if at all since there is almost no flow when the heater is off.  So a kink in the hose would not be an issue. 

I did this last year when my heater core sprung a leak during a classic car rally and had no problems.   I ran it that way all summer.
