Question about 1994 Chevrolet Camaro

1 Answer

Hose on front of water pump. Heater hose?

I have looked in various manuals and cannot find what hose is the one
coming out of the front of the water pump and around to the passenger
side of the car along the chasis or goes inside the chasis. The hose
is leaking at the connection to the water pump, and I want to replace
it.. Everything I look up is a Heater hose that does not even look like
what is on it... It is a 1994 LT1 V-8 Camaro Z28. Any help would be
appreciated,.

    Yes, I found out that it is a heater hose and it has a flow control inserted right before the

    connection to the Water Pump. I had to go to the Chevy dealer to get a scamatic of the hoses,

    and part number for the Flow control. Thanks for the information. That is what we are going to

    do, cut the hose after the bad section. The flow control broke when the old section was removed.

    Evidently it had never been replaced since the car was new.

If the hose is long enough, cut a short section [say, inch or two] from the bad end and reinstall the hose and clamp. The rest of the hose is probably OK.

I swap out the heater core and may hav installed the hoses wrong.I hooked up the hose from water pump to lower fitting and return hose on top fitting


It usually doesn't matter-it just circulates coolant through the core and returns it. But the hose going to the water pump is the return hose from the core. The other hose from the cylinder head or intake manifold is where the coolant comes from and going to the heater core. Take off the hose at the water pump and you will see a stream coming out with the engine running and the heater control on hot. Try this and if the stream is not good, try swapping the hoses at the core- I mean take the hose to water pump and fit it to the core's upper hose, and the inlet hose to the lower fitting. It shouldn't matter, but let us know.

Monte Carlo heater core


I don't know if top or bottom, but the heater core inlet will be the hose coming from either the intake manifold or a fitting on a cylinder head. The outlet from the heater core goes to the front of the engine, it goes into the water pump. I think all GM engines are like this, and almost all engine designs likewise. On a 1992 3.8L, for example, the heater core inlet hose comes from the intake manifold on the passenger side. The heater core outlet goes into a fitting on the water pump (lower front of engine).

How can iget the hot water to the front heater coil both hoses stay cold


does the engine's cooling system thermostat open and close?
(does upper and lower RAD hose feel warm then warmer)
are the hoses to the heater coil (both hoses) free of obstructions?
(pull them off and blown them out)
is the heater coil able to pass coolant in one side and out the
other? Hook up garden hose to inlet house (disconnect from pump hose nipple) disconnect heater outlet hose from pump and drop into a pail to catch outflow)
Does the water pump work as it should? ( should see fluid flow when looking through rad cap opening while engine is running)

Water disppaearing out reservoir box ew radiator.......


Could be your water pump is leaking or a loose hose clamp,to find out for sure Sherry,you need to get under front and look for antifreeze,will need a flashlight,and follow to where it's coming from.Usually when cold,the antifreeze will be on that mark on the overflow container,then after driven for a while,it will expand and rise to the hot mark.You also have heater hoses going to heater core,is floor board in front wet.You have a hose going to thermostat and water pump.Also check radiater cap.

My 1995 F250 is leaking radiator fluid under the engine behind the fan


Is antifreeze coming from "weep" hole in bottom of case under shaft nose?
is it coming from the heater hose (small hose coming of side and going into firewall to heater core inside engine compartment?
is it coming from bad gasket between pump and front case?

get a paper towel and dry these areas then start engine. when it starts leaking that will tell you if you need to change the water pump (gasket leak or weep hole shaftseal leak) or if you just need to replace/repair heater hose.

Heater gives warm air then cool air


That's usually a dirty,clogged heater radiator. How's your antifreeze look? If it's dirty,flush the system out.
But to get your heater working........look down on the firewall and you'll see a coupla' heater hoses entering thru that go to your heater radiator. The trick is to flush backwards from the usual flow direstion that trapped the debris in there.
The flow goes from the hose near the thermostat area into the heater radiator and comes out the other hose and returns to the water pump.
Take these hoses loose from the thermostat area and from the water pump,when the car's engine has cooled.
Now take a regular garden hose with a pistol grip nozzle(just the old cheap type) and hold it tightly to the water pump heater hose and force water back thru the heater radiator.VERY IMPORTANT! DON"T get any water in the alternator and don't let any get into the dipstick of the oil or transmission while you flush!!!
Make sure the hose is directed downward where the debris will come out. (you can tie a large white sock onto the end of the hose and you'll see the debris that you flushed out when you turn it inside out)
Now you have an option to funnel some radiator flush down into the heater radiator and let it sit for an hour,and then reflush the heater the same way and then reconnect the hoses.Enjoy! don-ohio (:^)

I have a leak coming from the area that my lower radiator hose connects to. Not to the radiator but to the engine component. Could it be a seal? The hose connects from the radiator bottom and travels up to...


it connects to the water pump on the front of the engine could be a bad hose or it could be water coming out of the seep hole on the water pump and running down the hose, does this hose have a smaller hose coming off of it in the middle because this connects to the heater if it does.
