No Heat on Nissan

It can be issue with air in coolant system

Bleeding coolant line on Nissan pathfinder



To bleed the coolant system ...................

• First of all  remove the radiator cap. 
• Then install the coolant bucket. 
• Fill the bucket about 1/2 way. 
• Then raise the front of the car as high as if it were on ramps. 

This way if there is air in the coolant system, the circulation brings it to the highest point.

• Then turn on the car, and put the heat on speed number 4, recirc mode on, and face mode. 
• Now on these stage its advisable to  to rev the engine to move the coolant around to get the air out. 

After you have good heat, and little to no bubbles in the coolant bucket.
Then the coolant system is properly bleed. You should have good heat when bleed properly.
Now to confirm that procedure is worked right,( BE VERY CAREFUL) put your hand over the vent and hold it there for 30 seconds, you get a slight burning sensation. That is perfect heat.

These details will help.
Thanks.
