have you tried any radiator flush kits? Try this , drain the radiator below the heater core lines and disconnect both line, take compressed air (air compressor) with a rag and a blower, stick in one end and release the pressure, watch out it will blow some junk at you. put back together and refill

How do you change the heater core in a 87 Ford F-150?

To change the heater core in a 87 ford f150 is easy. Just remove the glove box and then behind it there is 7 bolts. After you remove the 7 bolts then just remove the cover and behind it is the heater core. By far the easiest heater core I ever changed.

Where is the heater core on an 87 escort?

It is inside the heating A/C housing. The dash has to come out to get to it. A very involved repair. Even the most experienced master mechanics cringe at having to do a heater core repair. I would suggest putting some aluminum stop leak in the radiator. It will stop the leak in the heater core and will save you the grief of pulling the dash out.

How do you get to the heater core on a 1986 Ford Thunderbird?

it's not that hard you just need to have pictures to guide you through it. i did my wife's heater core in 87 t-bird. Take the entire console out of the car to facilitate removal of nearly all of the dash Most of the dash will have to come apart to change heater core Also the air ducts air box as affected Better just to bypass the bad core under the hood to return the hot water back to the engine and just leave the bad heater core alone Use a shop vac to suck remaining water from the bad heater core At a shop the change of the heater core costs from 300 to 400 dollars because of all of the labor


How do you replace the heater core in a 87 Honda Prelude?

I'm pretty sure you would have to remove the dash unless it's accessible below the passenger side of the dash. Root around there for anything. If it's leaking in the cabin you can locate it easily.... I replaced the heater core on my 1987 Honda Prelude Si last year. The air conditioning evaporator box will not allow you to get to the heater core without removing the entire dashboard. First you have to remove the instrument panel, and then remove the rest of the dashboard to get to the heater core. I bought a 87 Prelude shop manual on eBay and that really helped in showing me where all the bolts and screws are located that hold the dashboard. I had 1 screw left over...but the car and heater core work great!
