ok, I promised myself I would finish with the motor install tonight, and I only have a few more hours but I am almost there. but for the life of me I can't figure out where the hose goes from the top of the waterpump on an L98. . am I completely fried in the head?? can anyone throw me a smack in the face? thanks guys

 

Heater hose maybe ?

 

where does it go though?? any idea?

 

Doesn't one of them go to the heater core?

 

loops up and back to front of the t-body-other side of t-body goes to heater valve or to firewall seeya
hey i read it wrong plug that water pump hole and move on the hose i am speaking of comes off of a nipple at the face of the intake manifold. :rockon: nuthin goes to pump

 

Actually, there is a hose that goes to the top of the water pump, and it is the heater hose. (It's about a 1" threaded hole, right?)

IIRC, for our cars without that black valve thing sitting near the AC condensor on the passenger's side, that hose runs from the firewall to the water pump. I think they stopped using the water pump as as source for the heater when they added the little valve thing.

Someone correct me if I'm wrong.

 

ok, well I just went to home depot and bought a water connector so that I could block it off, but use it in the future if I need. thanks for the help guys

 

do you mean a/c evaporator? condenser is in front of the radiator. no tpi engines in camaros used a bung directly off the w-pump to accept hose. the black valve thing aka heater control valve showed up on tpi cars with a/c in 87 or 88 or therabouts. tpi engined f-bodies prior to those years did not use a valve either with or without a/c. but even with the engine oil cooler setup and related coolant hoses, no hoses tied into the pump. the rt.side of the radiator has a nipple on it below the filler neck.it is the other end of the t-body to heater control valve to h.core or oil cooler (or both) coolant loop that started from the fitting screwed into the ft.of the intake. now tbi cars and carb cars do tie into w.pump im fairly certain of that.

 

ok, so the general opinion is that I don't need it, right??. . I blocked it off, but it can be easily removed if I need to, just used pipe thread that is used to connect two steel pipes and then put an end cap on it.
