Just bought truck. Heater hose shorted from pump to return (heater not hooked up) Is there a special valve in supply or return line or is pump supply just hooked to bottom heater fitting, and return to bottom heater fitting? thanks

This was probably by-passed because the heater core was leaking badly. If you have replaced it there is usually a mechanically actuated valve on the upper (in) line, depends on model and year...

There are no valves in between, basically it goes in and comes out, simple process. More than likely heater core had a leak as you probably already know, that is why it was bypassed. Good Luck.

Be careful ! usually when people do that its because the heater core is leaking and they bypass it with the hose so if you hook it back up you might have a mess inside of truck !

1997 Taurus ford GL 3.0,6cyl. Heat runs cold to


Some early cars have what is referred to as a hot water valve under the hood . It is hooked in one of the heater hoses , the supply side . The other hose is the return side , once the hot coolant goes through the heater core it goes back to the engine to get heated up again. This hot water valve is operated by engine vacuum. If you look at the fire wall or bulkhead , you should see two hoses going into the inside of the vehicle. those are the heater hoses. look for the valve on one of them. If you vehicle doesn't have one of this valves , you possibly have a mode or blend door problem . Does you car have Electronic Automatic Temperature Control or manual A/C-heater system ? The heater blower does work , all speeds ?

Where does the 5/8 heater hose hook up to on a 1972 nova and is it the pressure hose


They are both "pressure" hoses since the pump pushes the coolant through the system when the valve is opened. They will both go on to the heater core. One to the top, the other (return line) to the bottom. The upper one may have a control valve in line with it before it enters the core. The valve is operated by the heater controls and opens/closes to give you heat.

How do i by pass heater core on a 1989 lincoln continintal signature series

No heat from heater fan works fine


Both heater hoses should be HOT to the touch (coolant return hose should be slightly cooler than the supply hose). Now, first thing to do is to see if you have vacuum at the heater control valve when the lever is in the HOT position. If there is no vacuum, then you have a problem with the heater control panel or vacuum supply.
If you do have vacuum, then it's probably a bad heater control valve. If you supply vacuum from a hand vacuum pump and there is no change in hose temperatures, then the heater control valve is bad. You can take it out and look inside to see if it opens and closes.
If the heater control valve is fine, then you probably have a clogged heater core. The construction of a heater core is such that if it is 95% clogged, water will still pass through the remaining 5% and come out clean.
If everything checks out fine, then you have to look inside the heating vents for an obstruction.Thanks

No heat,engine temp.is normal


the valve that allows the hot water into the heater core is not opening. most likely electronic issue. also check all vacuum and electric lines.

No heat engine gets warm but heater wont switch from ac to heat


Start searching for a vacuum leak. The dash switch operates a vacuum assembly - but if the line is cracked, it "door" will not change position.

Defrost will not come out vents


Check your coolant level first. Next check your heater control valve. With engine at operating temp and heater on high, do this:

1. Heater hose from water pump should be hot (if not, water pump may be dead or thermostat is stuck closed)
2. Heater hose from thermostat housing should be hot (if not, thermostat may be stuck closed or water pump is dead)
3. Heater hose going to heater core should be hot ( if not, heater control valve is not getting vacuum from heater control unit, or valve is broken)
4. Heater hose returning from heater core should be hot (if not, heater core is blocked, undo both hoses to core and flush with water hose until clear)

Test thermostat: with cold engine cranked, watch water temp gauge. As it gets hotter and hotter, when the thermostat opens, the temp should drop suddenly and then go back up.

Test water pump: with engine at operating temp. Squeeze top radiator hose tight, when you release it, you should feel/hear a surge of water. It is much like when you pinch a water hose closed and release it.

Test vacuum from heater control unit to heater control valve: undue vacuum line from control valve. It should have a vacuum when pressed against you skin in addition to releasing the actuating arm on the control valve.

If there is no vacuum, a quick fix will be to disconnect the plastic actuator from the silver arm on the heater valve. This will let the hot water to always flow to your heater core.
