I suppose your blue and red would then be backwards in the winter Quote Selected
Unique Repair of bad heater core Reply #17 – December 11, 2009, 10:35:13 PM think about it guys the a/c core will handle the hot temps. if u think im wrong look at a heat pump system on a house even though its not antifreeze it does reverse the flow of the refrigant to heat ur house making the a-coil go from a cooling to heating coil . only they are made to handle high pressures . so the a/c core should out last the heater core. heater core made of copper , a/c core made of aluminum.so it should stand up better to corrosion alot better.but hell ive been wrong before. lol Quote Selected

Unique Repair of bad heater core Reply #20 – December 12, 2009, 02:39:13 PM I used this trick as a "temporary" fix. It got me through 3 winters. The only down side was the heat was either on or off. During the summer, I just used a metal coupler and bypassed the evaporator until I needed it again the next winter. Temporary could have easily become permanent if I had a way to control temperature. In 3 years it never failed to bring me toasty-warm heat. Quote Selected

Unique Repair of bad heater core Reply #23 – December 12, 2009, 10:23:41 PM Quote from: 84TBirdTurbo42;302013i was just wondering of the corrosiveness with antifreeze thats allMost newer antifreeze has additives, to keep all the aluminum in the newer motors safe. So I would assume the core would be reasonably safe.:D Quote Selected
Unique Repair of bad heater core Reply #24 – December 19, 2009, 12:33:28 PM I did this to my white coug several years ago and posted it on the old board.only one problem,,,,,,,, YOU HAVE HEAT!!!not only do you have heat but you have it on vertually every setting except off.I dont care though, it solved my problem.

Unique Repair of bad heater core Reply #25 – December 19, 2009, 01:53:52 PM Does it increase the intensity of the air? The setup in my car (stock) doesn't do a whole lot, and I might try this to incease the heat. It takes forever for the car to warm up, and its either sweat buckets or freeze your stones off, and I can't understand it. Quote Selected
Unique Repair of bad heater core Reply #26 – December 23, 2009, 12:20:14 AM your just gonna have to take the blower motor out and clean it,, check the duct work, check for kinds in the flex hose ect. my blower is great,, perhaps your burshes on the motor itself are getting worn and its speed is slower ,,although you would likely blown the on board fuse at teh resistor block.

Unique Repair of bad heater core Reply #28 – January 13, 2010, 05:41:43 PM It's good advice, when my taurus had a transmission overheat issue I started using my a/c condensor for a transmission cooler. Worked like a charm! Quote Selected
