what are the heater hose sizes

[mppaintball]

about to change my heating core...AGAIN. and i only have one hose on it right now because the heating core is bypasses. So i need to know that the 2 heater hose sizes. Thanks. I replaced the heating core a couple of months ago but it cracked in the same place as the one before that. at the joint of the inlet pipe to the main part of the heater core.

why not get a line that runs between the two hoses and clamp it together, that will solve the issue for now too. Its better then having fluid run into the bad core and into the vehicle.

i did have one hose ran from the out to the in. But i live in washington where it cold and rains 8 months out of the year so it was about time to fix it again.
