SOURCE: 2004 NISSAN ALTIMA 2.5 NO CABIN HEAT..ENGINE AT OPERATING TEMP.

If the engine is not over heating than most lilely it isn't the thermostat or waterpump that is causing the problem. Check the heater hose coming out of the manifold and see if it is warm to hot. Next check the return line from the heater if it is still cold or moch cooler than the inlet, the most possible problem is the heater water control valve if this model has one or possible the core of the heater is plugg with slime cause by some antifreezes setting during the summer months while not being used. If this is the case than remove tihe two hoses and back flush the heater core with water pressure until it runs clear. I have had this problem before and this cured my problem. I also had to flush the engine and radatior also. Hope this help. .

remove both hoses from engine that passes through firewall to heater. put a stiff piece of wire in the hole and make sure it is clear. If there is no restriction, then the heater is choked up

I dont have any heat and i need to know how to replace the hearter core, however the windows aren't fogging up so maybe its the thermostat


the only way you should have to replace a heater core is if it leaks or gets plugged up. When motor is hot feel the two hoses that go to the heater core. one should be fairly hot and the other should be the same but if one is just warm then follow hose and locate a flow valve and check for operation. OPening and closing with control hot /cold knob. Check coolant level in radiator while cold as well as fill reservoir to full when cold. Also remove radiator cap when cold and warm truck and check for flow of coolant. if lower radiator hose is hot hot hot and upper hose is cool then thermostat may not be opening properly, or thermostat is stuck open not building heat. You didnt mention if truck was overheating?? If its not i'd check for the flow valve operation, if it is i'd make sure coolant levels are full and waterpump is working.

On almost all cars if you follow the upper radiator hose to where it goes into the motor, that is where the termostate is.

Nissan sentra 1994 use termostat


if you're referring to the thermostatic valve in the coolant line, then yes, yes it does have that. it's located at the end of the upper radiator hose (return line) close to the engine. it's inside of what may look sorta like an elbow pipe.

How to change a thermastat 1994 ford escort with a 1.9 engine


1.9L Engine

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the air intake tube, crankcase breather and PCV hose.
  4. Remove the ignition coil pack and bracket.
  5. Remove the upper radiator hose.
  6. Remove the ignition coil pack bracket.
  7. Unfasten the heater hose inlet tube bracket bolt and remove the heater hose inlet tube from the thermostat housing.
  8. Remove the three thermostat housing attaching bolts, then remove the thermostat housing and gasket.
