You may have a leaking engine head gasket or a clogged radiator. Do not drive this until the problem is repaired or you will do serious damage to the engine.

SOURCE: water not circulating,we put on radeator cap water pump ,intake gasket,flush heater core,engine radeator,reservoir

sounds like your air locked inside there should be 2 bleeders one by the thermostat and in the front of the engine near the pulleys you will probably need a 5/16 or 8 mm wrench to crack them open do one at a time while running make sure all the air gets out and you get a steady stream of fluid coming out once it is bled or you think all the air is out go inside the car and see if you have constant heat if you do then all the air is out.also turn on the heater while bleeding it.

SOURCE: 1997 Toyota Avalon over-heating problem due to low coolant level

Could be buring coolant from headgasket leak. thats the only other way coolant can leave your engine besides a leak.

Side note:
I strongly reccomend in the future not to use ne kind of coolant stop-leak stuff. you have small passages coolant needs to go through and that stuff also cloggs up those areas. alot of people dont think that far ahead. so alittle info for the future for you. it also cloggs up your heatercore and radiator. and will cause faster corrosion in those areas.

Renault Megane Dynamique 1.6 2004 - Heater fan stopped working - wet front footwells


Im almost sure that your problem is a broken or leaking heater core and needs to be replaced cose 1 your coolant level allways will be low due to the leak and 2 it could damage your blower fan motor. if in winter time you need the heat fixit... If not you could cancel the 2 waters hoses going to the heater core. hope this helps.

LOW COOLANT LIGHT COMES ON SOMETIMES AND TEMP GUAGE SHOWS ENGINE GOING TO OVERHEAT. HEATER GETS COLD. IS IT THE THERMOSTAT?


There may be a thermostat problem, but your symtoms indicate low coolant level. When coolant is too low, it will not circulate, so you get no heat in car, and the coolant remaining in engine block overheats because no cool fluid coming in.
You need to fill the system up properly then look for leaks.
With cold engine, open radiator cap. Fill with antifreeze directly in radiator. Start engine, top up rad if level drops. Put heat control on Hot. Fan on low, heat on high. Gently rev engine and top up rad as needed. IF as engine heats up, it starts kicking fuild violently out of radiator, then the thermostat is bad. if not, then recap radiator, top up overflow bottle and you're done. Look under car for any sign of leaks. Steady dripping indicates a leak, then address that.

Driving home last night, the temperature guage fluctuated wildly between mid-range, max then back to mid. Fan came on for a long time once the car had stopped. I topped up the coolant as this was low but...


Sounds like fan belt is slipping. When it slips waterpump doesn't spin fast enough to circulate coolant. Also if there's an air pocket in cooling system it'll give similar symptoms.

Hello, I own a 1998 Altima (GXE). 160 000 km. For the last two days, the motor temperature guage needle indicates low motor temperature (1/4 between the C and the H). Yesterday I was in heavy traffic for...


First thing is the that the coolant temperature sensor is quite different to the temperature sender that is monitored on your dash board. Assuming everything is working fine the thermostat may be stuck open. This would cause coolant to be circulated without restriction and so remaining cooler than usual even when the engine is at running temperature.

Am experiencing inconsistent heat and/or defrost even after engine has warmed up. Also noticed engine temperature guage is noticably running hot. Coolant level or thermostat?


Most common problem here is the coolant level. If the overflow tank is full of coolant and you are experiencing heating/overheat problems, the thermostat is likely bad (especially if you've used a sealer due to a leak). A clogged thermostat will prevent coolant from circulating and impact your heater/defroster.

No heat in cab.


You did not BLEED the radiator and it's over heating.

Take off radiator cap when engine is COLD

Start engine

Let it idle until it's HOT

As it heats up you will notice air bubbles coming out of the radiator filler neck.

Let car run until you don't see any more bubbles

Fill radiator coolant to keep it topped up to the hot mark.

Put radiator cap back on once you hear the fans kick on.

Done

You should now have tons of heat

Providing your water pump is working

2002 caravan, heater problems


That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.
