Default Heater core replacement

Greetings all. I have an '02 Ranger Edge, 3.0L, 2WD, stock. The cab has been smelling like antifreeze for a week and the windshield is fogging up. I checked the coolant system and saw nothing leaking. Today, while driving, I turned on the a/c, and antifreeze laced steam poured out of the vents. It also started to overheat. When I got back to the office, THEN I saw the antifreeze leak under the firewall area. I strongly suspect the heater core needs to be replaced. Everyone I have spoken to said to "take it to a pro".
My question is this: is this something that can be done in an afternoon? How difficult is it to do?
thanks

I would say it is a good 3-4 hour job. How mechanically incline are you?

Thanks for your response. I have pulled engines, rebuilt transmissions, water pumps, alternators, rebuilt carbs...but pulling dashboards is probably out of my league. The heater hoses go through the firewall on the passenger side. I have bypassed the heater core for now, but it seems to throw off the coolant temp as it runs much cooler now. I did replace the radiator cap and the thermostat, in hopes that this would help. It didn't. The local Ford dealer quoted me $700 to do the job. Winter in far south Texas is almost negligible, so I may try to leave it bypassed until $700 rains from the sky.
Again, thanks for your response and advice.

Default Heater Core Replacement

I've replaced several heater cores in 4 cyl Rangers and it is a all day job (4-6 hours). You have to remove the dash, right side inner fender wall and HVAC blower box. It's not that hard but very time consuming. Don't worry about the dash it's only held on by about 8 bolts, two by each door and a few under the windshield. let me know if you want to try it and i'll give you some pointers.

heater cores are a no brainier job it takes about a hour. did my dads 2.3 in less then a hour. if your truck keeps over heating just disconnect the in and out hose's going into the firewall that connects to the heater core. and connect the two lines with a tube of any kind and make it your bypass in until you get the new heater core. dad did it to his 2.3 until i changed it out.

Ranger Tech. It looks like I will need to replace my heater core on my 2001 ranger 4 cylinder. I know I will have to take the dash down. how do I deactivate the passenger airbag? Thank you in advance.

disconnect the battery, wait 5-10 minutes. but honestly, you won't have to pull the passenger air bag from the dash.

dash has to come completely out. column has to come out. taking the shifter arm off will make your life easier.

All that has to be done for the heater core in a 2001 2.3L ranger??

I thought it was just behind the glove compartment on the passenger side?

Thanks,
-Nigel

Default Re: Heater core replacement

Damn!

Is there any true way of knowing if the heater core is going bad?

I ask only because I seem to be loosing just a little bit of coolant and there are no spills on the ground nor are there coolant going in the oil or anything of that nature.

My only guess would be perhaps a heater core as I was told if the passenger side foot well is wet that's a great indication, however the foot well is completely dry.

I know when I was doing other things in the engine bay I saw a tube sticking out towards the bottom with nothing attached to it inside the passenger side firewall... is this a drainage for the heater core?

I don't think I smell coolant inside the cabin but how would I make sure? I do have a smell but it smells like stink bugs or I should say dead stink bugs, which I did find a lot behind the dash for some reason...

I would just hate to buy a $40 heater core and take it all apart to find out that mine is fine.... Do these rot out after a while?

Thanks,
-Nigel
