Window Defrost


Recommended Posts

There is only ducting to the inside of the windows. The outside is taken care of by the wipers.

 

How hot is your heat? Speed is relative to how moist the inside of the car is and how hot your coolant is / how good your heater core flows - and you of course need the damper doors to be working to direct that hot air to the windsheild.

It's all in how you use it. With the garden hose adaptor spliced into the return line of the core, you can then disconnect the supply line, and crimp off the return line on the water pump side of the hose fitting (vise grips and some quarters or washers). Then when you turn the water on it will force all the pressure through the heater core in reverse of the normal flow (and typically at much higher pressure and volume than the core usually see's). This will blow out any accumulated debris through the supply hose and (hopefully) improve flow through the core. You can put some radiator flush in the core - disconnect both lines to the core, fill it through BOTH hoses till it's full, and tie the hoses up so the flush stays in the core. Wait the prescribed time interval for the stuff to work, then flush as per my previous directions.

 

It's really very simple and takes little time.
