1998 Honda Odyssey -- No heat?

1998 Honda Odyssey heating system will only blow cool air and the coolant temperature gauge is grounded at the bottom of the scale. If we sit (static/not moving with the engine running) the air will warm slightly. The air is cool when the vehicle is in motion. Is this a thermostat problem?

My 1996 honda accord doesnt heat up like it suppose to..unless its juss parked without any movement.. I drive it 2 miles away and it still doesnt heat up im concerned !! Any help ????


Thermostat stuck open?
Faulty temp sensor or gauge?
If heat comes out of the heater, engine thermostat is ok. That will isolate it to probably the temp sensor in the temp indication system (sensor & gauge).
The cooling system should be full. Temp sensors cannot read the engine temperature of steam or empty cooling galleries.

Air pockets in radiator


Air can be purged. While your engine is cool remove radiator and reservoir caps. Place funnel in radiator. Turn heat to the highest position and start vehicle. Add coolant to radiator as needed while vehicle warms up. You should see bubbles coming out of radiator. Fill reservoir to between cold and hot fill lines. Replace caps when bubbling stops but before coolant temperature reaches normal operating temperature. Never remove the radiator cap until engine has fully cooled down.

Mg zr blowing cold air all the time.losing water over period of time and temp gauge goes up into red and comes back down again.could it be head gasket?


Check all coolant hoses for leaks, the coolant/water has to be going somewhere. Fill the engine with coolant, run engine til warm and look under the vehicle for signs of coolant on the ground. The best resolution is to pressureize the system and check for leaks. Your blowing cool air because there is not enough water in the heater core to properly heat.

Heat/Cool gauge fluctuates inconsistently


You might check the coolant level after the engine cools,if it's low add 50/50 mixture of coolant and water. Keep an eye on the level to see if it happens again. You might have a small leak in the system. Good luck

Car will not heat. Blows out cold air


Firstly check the coolant level when the engine is cool. If fluid is at correct level then more then likely thermostat is stuck open. Have coolant system flushed before installing new thermostat. Also check water pump to make sure it is not leaking out of the weep hole.

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.

Help is HERE!
It looks like an Air lock scenario!
Park vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater to hot blower on full. When at operating temp keep clear of coolant filler area and listen, hopefully gurgling then a boil over, wait and then top up with very warm water/coolant let settle it may boil over again whilst air is still in system.
Check for heat inside car, if hot and coolant settled replace cap but keep an eye on temp gauge for a while as air lock may still be further along cooling system.
Please press the Blue button if sorted!

1997 Honda Odyssey thermostat


Honda recommends that the cooling system be topped up with coolant four times as part of the refill process. When the engine is fully cold open the radiator cap and add coolant until full. Run the car until fully warm with heater at maximum. Let it completely cool down. Remove radiator cap and top up with coolant. Repeat this process two more times. This helps purge the air out of the nooks and crannies in the cooling system.
