Heater core

[Patrick Carman]

Heater core issues and maintenance are a growing frustration as vehicles evolve. But it doesn't have to be this way. Our current design engineers, (kids who went to college, but have no hands on experience) have decided to put often serviced components in areas that require a contortionist to push his limits. Case in point, the heater core. As you know, replacing a Journey heater core by the book requires a ridiculous amount of work. But it can be done much more quickly by a simple cut and splice technique of the aluminum lines by the heater core body, thus eliminating the need to dismantle the entire dash interior of your vehicle. Many you tube videos walk you through the process. With a little common sense this replacement could have been designed with quick couplers near the core location. Never try to remove the heater core pipes at the core to attempt to replace it. Believe me, it not only can, but will leak as your pliers are no match for the factory crimps. Speaking of dash removal to replace a heater core, that's like removing the vehicle body to get to the spare tire. Oops, I probably gave some young engineer a new thought. How about an access cover where two clamps are removed and the core then slides out and in in a matter of minutes? Oh, sorry, that's to much common sense and something today's engineering can't comprehend. Anyway , cut and splice your core pipes about 6 inches from the core and reconnect with a short hose and clamps. Damn, just saved about 3 hours of mickey motion!  Remember, analyze your repair and use common sense and you are way ahead.
