Exclamation how to replace heater control/bypass valve

Hey all. I've read up a bit on this site on how to replace the Heater control/bypass valve (on a 1998 ford explorer sport 4WD 6cyl), but still have some unanswered(and unasked) questions.

I went to CAP and grabbed one, was $21 bucks.

Now i'd like to replace it, but if i cut the hoses that are connected to the stock one(which is faulty), it seems like there will not be enough length left in the hoses to reach, is this true(buy new hoses) or should I be okay(cut and go)?

Also, before i start cutting, what preperation should I do so that not much coolant leaks out? is it going to spit out everwhere when I make a cut?

Thanks guys!

The hoses are simply just connected to them.. Just yank em off and then re-connect them to the new control valve.

Burp system afterwards.

My local Ford did not burp the system after they replaced mine, so my temp gauge reads colder and/or flutuates alot.

valve

i replaced mine just 3 weeks ago.

i noticed when the heater control valve started to drip onto the exhaust manifold making smoke.

it's an easy fix. I did not drain the system, very little coolant spills out, just a few ounces. Open the radiator cap first to remove the pressure and you'll be fine.

dont cut the hoses or you'll wind up buying new ones. Unclamp them. Twist & pull at the hoses until the valve comes loose. and replace. it's very easy and took me 20 minutes and i'm beginner skill level.

tools needed: plyers and shop towel

Where is the HCV located on the SOHC? Where did you find out how to replace it also? I need to replace mine but I can't find it.

Hey guys,

I was having problems with my HCV so I replaced it. Now that I've replaced it, I get no more leaks from that area (which was originally causing my car to overheat). I believe I connected everything properly but now the heat doesn't work anymore, it just blows cool air. If I leave the heat on, it opens the valve and that's when my car overheats. If I leave the heat off, the car doesn't overheat and I get no leaks.

Can anyone post a picture of how the hoses should be connected on a '96 model 2 WD Ford Explorer Sport? I will try to post a picture of how my hoses are connected if I can figure out how.

Thanks in advance.

I also need to know how the hoses are ran. The heater control valve blew up a couple weeks ago and I did a work around until I could get the part. now I do not remember how the hoses are connected. Thanks for your help on this issue.

j0rdantay10r : Sounds to me like you need to replace the heater core.

To 'burp' your cooling sys. you should uncap your radiator (while cool), allow your vehicle to warm up to op. temp. this should work out any air that may have been introduced during a coolant change or adding of fluids. You will know youre successful if the coolant in your radiator swirling and void of any bubbles.... if yo u dont see coolant swirling then youre a little low so add a bit and repeat!

i couldn't get my SOHC to burp to save my life after changing the lower rad hose. tried all the suggestions on how to do it. i finally decided to take it around the block. w/in a 1/4 mile the TEMP gauge pegged on high and the radiator puked into the reservoir and blew the cover open. i rolled it home, added about 1/2-3/4 jug more of antifreeze mix (once it cooled down) and then it was fine.

How can you tell if the heater control valve is going bad? I can hear pressure building up around that area every time i start up my engine..

the heater control valve will leak if it starts to wear out. as far as its operation, vacuum opens it and lack of vacuum allows it to close. when open it allows hot water to flow through the heater core. if your temp gauge reads normal, the heater control valve isn't leaking and you're getting heat - all is good.
