You will experience this problem if you have air trapped in your cooling system. This may need to be bled out. When you have air pockets, you get airlocked coolant that won't circulate through the heater core unless your water pump is moving more quickly under acceleration. Check for coolant leaks also.

Your present thermostat seems to be stuck in the open position and not allowing coolant to warm to temperature. I think you should have your thermostat changed. This will give you heat. GOO LUCK FRIEND.

Heat delayed


heat not blowing or not getting hot? if it's not blowing it may be the blower motor going out but if its just taking a while to get hot it could be the duct exchanger which could be a vaccume leak or you could be low on engine coolant, if the engine coolant is low the heater core doesn't get enough coolant to warm the air that passes thru it.

2007 Nissan Altima air conditioner & heater takes a long time to come on


Your Air Conditioner might be low on refrigerant. If the AC doesn't cool down and had signs where it took a while to start cooling, you likely have a slow leak. It could be that an O ring wore out and started leaking, or a hose developed a leak. Rubber components tend to be the first parts that wear out over a period of time. A shop can confirm if your 134A refrigerant leaked out of the system.

Does 2007 altima 3.5 have a chain or timing belt


After 2002 Altima offers two types of engine: the new 4 cylinder 2.5 L QR model engine which is fairly powerful (175 horsepower) and, I believe, one of the best engine in its class the 3.5L V6 VQ model engine with 240 horsepower. The same V6 model as in in the Nissan Maxima, Pathfinder and Murano.
Both engines feature continuously variable valve timing using a silent chain instead of timing belt. Throttle cable is gone - the throttle operates electronically by wire based on gas pedal sensor readings. This design provides smoother transmission shifting and lower emission.
The 2007 Nissan Altima 3.5L Sedan, has a Timing Chain, and an Ignition Coil Pack. NO DISTRIBUTOR.

Nissan Altima no cool air blowing or hot air blowing


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
