Hello)Autumn came, then late autumn. And now everything is covered in snow)
And I began to notice that the antifreeze was “escaping” from the expansion tank, not quickly, but the level was decreasing.I thought about it at first. Then I began to look closer.. Then I began to sniff.. Then I bent down. Then I looked down under the 2nd heater. The problem has been found. Something was dripping in the 2nd heater. There are not many options here - a radiator or a tube.
I decided to get to the 2nd heater. At the same time, take a look at the motor, as it creaked and rattled in the severe cold.
A few tears, screams, disappointments and the side panel was removed (I had a lot of questions for Nissan engineers - why put the heater in so deep, what’s wrong with you??)
In general, I did not find any antifreeze leaks, but the entire heater niche was covered in antifreeze and dirt. I dismantled the motor and ordered a new one. We also had to disconnect the antifreeze tubes and loop them, thereby eliminating the heater from working. The search for a heater radiator has begun...
Everything would be fine, you thought. But....
One day I was driving a tractor and heard an incomprehensible knocking sound in the area of the rear right side... I discovered that the body fastening of the body had rotted in the area where the 2nd (damn) heater is located.. Thanks to the mixture of dirt, antifreeze and water, as well as a low bow and respect to Nissan for the “quality” of the metal.
Well, the procedure is standard. A little metal cutting, a little welding, tears, sparkling water (unfortunately Coca Cola left us)..BUT...
At some point during welding, due to an increase in the temperature of the metal (which is logical), the 2-layer bitumen insulation caught fire (the previous owner kindly covered the insulation from the inside of the car).. As a result, a mini fire of the 2nd heater. I had to run into the house for a fire extinguisher, since there was nothing really that could be done to put it out. I removed the plugs from below and inserted a fire extinguisher hose through the holes and extinguished it....
RESULT. The housing of the 2nd heater melted. I ordered a used 2nd heater + motor housing and motor.
Morality. Are you going to do fire work? Have a fire extinguisher nearby or get burned.
..Winter is coming..
