Annoying CEL from secondary O2 sensor and dead Cat? Here's a cheap fix!!

Yes, spark plug anti-foulers work for clearing Check Engine lights for a dead cat. The secondary O2 only serves to monitor emissions, and does not effect how the car runs. If your cat is dead, remove the secondary O2 and mount into a spark plug anti-fouler (available at any auto parts store for a couple bucks). First you must drill out the bottom of the anti-fouler so the sensor can pass thru, then screw the anti-fouler onto the O2 sensor, then re-mount the O2. Voila!! CEL should clear itself within a few days (it takes a certain number of engine "cycles" of starting/stopping before the light will clear).

Thanks to pac1085 here are the symptoms:

You replace the coolant flange or something else in the middle of the thermostat and the reservoir. You fill up your coolant/water mixture. You then crank your car and it overheats and the thermostat doesnt open.

The thermostat being open can be checked by touching the lower radiator hose to see if its warm. Warm bottom hose = thermostat open. Also having the heater working in the cabin will tell you if it is open. You will need to let the car warm up to check this.

The likely cause of this is air in the cooling system. To remove the air have your car turned OFF. Pull off the left heater core hose where (under the accordion cover) where the bleed hole will allow the air out but the end is still attached to the flange.

_Completely_ fill the coolant reservoir and keep it filled through the process otherwise coolant will not enter the crossover pipe. Unscrew the three screws that attach the coolant reservoir. Lift the reservoir in a way that the coolant can enter the metal crossover pipe through the small hose on the side of the reservoir and ensure the reservoir is higher then the bleed hole on the heater core hose. Eventually you will see constant stream of coolant come out of the bleed hose on the heater hose.

Reattach everything in reverse order and you should now have a bled cooling system.
