SOURCE: 2005 Pathfinder Heat Flow problem

I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.

I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.

But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!

As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!

Hope this works for you, and I hope I can figure out my rear heater problem as well.

SOURCE: 2002 Chevy Impala low coolant light is on

I had this same problem with my 2002 3.4L engine impala. Unfortunately, there was a coolant leak at the lower-intake manifold, caused by a cracked gasket. I replaced the gasket, water pump, thermostat, spark plugs and wires and flushed out the heater coil. Didn't find out what it was until after spending 100s on Dex-Cool. I kept refilling it for months until I got a good mechanic to fix the problem whom told me that this is a common repair on older impalas and GM vehicles with 3.4 and 3.1 engines.

2002 dodge intrepid the heat blows but doesn't get hot! Had the thermostat replaced but still no heat. What would be the problem?


either a heat switch is not switching heat to the compartment or else the thermostat in the cooling system is defective. when it is not open it does not let hot water to the internal heating system, has your engine been overheating or running hot? also as this would be a symtom.

2002 Nissan Altman looseing anti freeze but nothing under the car


Many possible causes. Leak can be when you drive, but not show on your driveway. The heater could be leaking into the passenger area, though you'd likely smell the "maple syrup" smell of anti-freeze.

It's also possible that you have a head gasket leak into the coolant, causing the overheating, and blowing some of your coolant out. Get a compression test on the cooling system, and a compression check on the cylinders.

Heat doesnt work


check your fluids radiator should be full and resavor should be at full level if you dont have enough anti freeze it wont push fluid into your heater core also pay attention to your tempature gage if the temp is low you wont get good heat your thermostat could be stuck wide open I would try adding anti-freeze first though that usually fixes it make sure its 50/50 if you just add water sooner or later that water will evaporate

I have the old green anti-freeze in my vehicle , the main heater hose is getting warm but no heat, does the anti-freeze matter ?


NO, but thats the incorrect anti-freeze. It should be ORANGE Dexcool. Both hoses in and out should be HOT. if they are not, flush the heater core.

I am losing heat even though the heat gauge is almost at 210. What needs to be replaced?


You probably have a plugged heater core or radiator.Very common for these models with the dex-cool anti freeze.Check the hoses going to the heater core.They should be hot to the touch.Not warm but hot when the vehicle is at normal operating temperature.When it is cooled down and there is no pressure on the radiator cap,check the radiator and make sure the system is full.If the system is low you will not get heat.If this is the problem then check for leaks.If this has a 4.3 look for and intake gasket leaking.Hope this helps.Good luck.Let me know what you found.

HELLO I HAVE 1995 GRAND PRIX WITH THE 3.1 MOTOR. MY PROBLEM IS IM NOT GETTING NO HEAT. THE TEMP GAGE GOES TO NORMAL WHEN ITS IDELING WHEN DRIVING GET HOT THEN WHEN I PUSH ON BRAKE OR COME TO A STOP THE...


check the fan and water pump one of these is possibly ur problem when ur at idle there is no heat load and the radiator can dissipate that when ur driving causes more heat if fan isnt working the car wont cool same if problem is water pump at idle pump may be able to move some of the hot anti-freeze but when driving may not be pumping it thru radiator to cool

My car is not blowing heat...is this possibly due to it having only water in the radiator and no coolant/anti-freeze?


No, that is not going to cause you to have no heat. You have some other problem, be sure the rad. is full. Look at your coolant temp gage if it shows normal temp you should have heat. Try and check any fuses for a blow fuse. Give us more info.
