Simple question for you guys. I remember years ago, I connected the two heater hoses on my slant to bypass the heater core. Any issues with doing this? I guess the coolant would just constantly run through the lines. What connector could be used?
Agreed, the rubber caps do not last.I would avoid the rubber caps, at least on the engine outlets as they will rupture and usually at the worst possible moment (fine for capping the heater core outlets)
But, you can use this pre-formed "J" hose, Dayco 87617.
(alternate hose-Dayco 87618).
Trim as needed and it works perfectly, looks like it was made just for this purpose. I use it on the race motors.

PS: Badvert, on my race motors, I install pipe plugs in the head, and water pump. You do need to tap threads in the water pump. Even do the bypass hose with plugs. If running a T-stat, do not plug the bypass hose.
I agree for a street car. I would only use the plugs on a race car.Well, I considered putting plugs in, but with this hose, it is simpler to replace the water pump, especially if I have to do it on the road. I can use a pump right out of the box.

I run a summit flex fan and my slant runs cool , in he summer here gets to 85 to 95 and if you make a shroud even betternone of the parts stores had them. or at least didnt want to look for a "u" or a "j" shaped heater hose . they all kept asking what yearmakemodel... ugh... anyway. temp fix while i was in there swapping the water pump. would like to rebuild the heater in the near future to help cool the engine(slant 6). plus its in the low 50's here in Los Angeles. anything below 75degF is hoodie weather for us locals ;)

Have you found your heater hose reducer you were looking for? It's been 2 1/2 years since you asked !Simple question for you guys.
