How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.
confident get the screw clamps. those spring clamps you would be able to besides throw them over the hill by way of fact while they're used then they get susceptible. plus with the screw clamps you may continually tighten them in the event that they must be.
Honda guy has the best answer, but I have a couple things to add. If it is like my daughter's 1993 Accord, it is easier to do from under the car than above it. In that case the converter heat shield is nearby and it badly cut my wrist when I tried to get the valve hose off the heater core - put a rag on that wicked thing. Be very gentle while wrestling the hose off the heater core pipe that sticks through the firewall - the pipe is thin brass and easily deformed. It is best to cut the hose lengthwise and peel it off, and be patient. You will want to replace that bit of hose anyway. EDIT - one more thing. After refilling the coolant, find the nipple (probably on the thermostat housing) for bleeding the trapped air out of the cooling system. Open it half a turn and close it when a steady stream of coolant comes out. Top up the radiator - remember, always use proper coolant diluted according to directions with purified water, never tap water. Life is good.
the heater control valve is in the heater hose under the hood. on the passenger side of the car there will be two heater hoses going into the engine wall. one of them will have a heater valve in the line with a cable attached to it. drain the coolant from the radiator before removing the heater hose or you'll get coolant all over the place and coolant is toxic to animals. after you drain the coolant you can remove the clamps that secure the hose to the valve. have a drain pan under the car as some coolant will still be in the lines. once you remove both clamps you can take the hoses off the valve then disconnect the heater cable. install the cable on the new valve and install in the reverse order. fill the radiator back up will the removed coolant. you'll need to run the engine until the thermostat opens and the coolant level in the radiator drops. then top off the coolant and put the radiator cap on. hope that that helps
You have to take the whole dash apart. Not an easy job, and definitely not one for a novice.
