SOURCE: coolant leak on olds alero 2000

Engines are designed with frost plugs that are designed to blow out if the coolant jacket should become frozen. Look carefully using a light and a mirror (ladys compact works well) Following the block heater cord to the engine will help locate these plugs. You may find the block heater has blown loose as it is installed in one of the frost plug holes. Best of luck.

SOURCE: my 2001 ford taurus is leaking coolant on the

It could be a hose on top of the engine leaking back there. It could also be a freeze plug on the back of the engine. Its a round disk about 2-3" in diameter and is recessed about 3/8" into the block. Check those out and make sure all hoses are good and tight. Any hoses that are kind of puffed out above the clamp should be replaced

When the engine is cold,check the coolant level.

Make sure it's on max.

===

A coolant system should be flush every two years.

===

If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.

The DIY method is to drive you car onto a ramp or a steep hill.

Iet the engine cool off and top off the coolant tank.

Set MAX heat + MAX fan

Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,

Check coolant level and top off coolant when the engine cools down.



A shop will charge $75+ for this but using an air operated excavate tool!

========

A car with over 90K miles may experience linkage problem to the heater control valve.

The heater control valve (near the firewall) may be stick over time.

Open the hood and move the heater to max and min. Back and forth.

Clean and lube the linkage with WD-40 to free the heater control valve.

If it's a vacuum type heater control valve then cash for leaky vac. hoses.


=======
Move the fan switch back and forth to re-new the electrical conductors.

Pass a vacuum over the control panel to prevent dust build up behind the console.

SOURCE: changed thermostat and added coolant but 1997

could be waterpump?
i was going to say rad fan,but if so heater would be hot.
lack of coolant will make heater core to blow cold,if engine heats up with full coolant,usually means poor or no circulation.
water pump?
run engine with full coolant,at operating temp.with rad cap off and look in rad cap hole and see if there is movement of water inside rad.
[rad fan will not come on if water is not circulating through rad water pump?]

I have a 2001 Chevy Silverado my windows fog up after 30 mins of driving and the low coolant light comes on but I have changed the the water pump and heater core and thermostat please help


Windows fogging up is usually an indication of leaking coolant inside of the truck cab. Its possible you might not have tightened the connections properly for the hoses going into the heater core. (Low coolant light coming on is no surprise, since after some time of leaking coolant near or at the heater core, the level will drop to a point where its low and cause the failure light to come on.). See if you can make a visual inspection of the area near the heater core, you might have to remove some interior panels.

I have a 2004 Dodge Dakota inside widows fog up no leak in passenger side floor board but defroster clears the windshield in the center so you can drive and all windows will fog


It does sound as though you have a coolant leak causing the fogging. Do you get a sweet smell from the heater vents? That's a dead giveaway. Often the coolant does not get to the floorboard if the leak makes it to the A/C condensate pan. Then it just goes to the ground thru the firewall. Watch for loss of coolant in the system. If you have an appreciable loss, then you should look at the heater core as the most likely cause.

On the 07 silverado smell comeing through the heat vent


If you're going through 1/2 gallon every few weeks - you've got a leak. Since you smell it from the heater vents - it may very well be the heater core ($$$) that is leaking. Usually, you'll notice that the windows will fog up heavily as the coolant is very hot / steamy once the engine has warmed up fully.

Look for coolant puddles under the truck to get an idea as to where it is leaking from. If closer to the front bumper - it's probably not the heater core - if closer to the firewall - it could be the heater core.

THE DEFROST BLOWS OUT HOT AIR, BUT THE FRONT SIDE WINDOWS AND THE TOP OF THE WINDSHIELD FOGS OVER. HARDLY ANY AIR COMMING OUT OF THE VENTS ON THE SIDE OF THE DASH THAT BLOWS ON THE FRONT DRIVERS SIDE AND...


You didn't specify what type of vehicle.
If you have very poor air flow out the vents, later model vehicles have a hepa filter or cabin filter in line form the blower motor to the vents. It can be plugged quite easily and drastically cuts down the air blown into the vehicle. Check to see if they are plugged. Secondly, Check your coolant level in the rad and reservoir. If the windows fog up when cold and air flow is good it could indicate a leaking heater core. Check the passenger side floor for signs of coolant again I don't know the type of vehicle, some heater cores are located at the firewall under the hood.

HEAT NOT BLOWING HOT ENOUGH


First check coolant level and strength. If good condition most likely stuck open thermostat, just follow the upper rad hose to the engine. Remove the throttle cable bracket to access the 2 bolts holding the thermostat housing to top of engine. Make sure engine is cold before removing, you will loss a little coolant when replacing. Other causes could be plugged heater core, with engine running at operating temperature on gage. Follow the 2 heater hoses the the right side firewall (where they go thru into cab) one should be hot and the other warm (if the outlet is cold, heater core is plugged). The waterpump and cooling fan are direct drive off the engine and not usually an issue on this vehicle.

While driving my 95 explorer i noticed the heater wasnt getting hot its luke warm and when i turn on the defroster i start to smell anti freeze and all of the windows fog up


no heat is probably low coolant or bad thermostat,although you have fog and smell ! the heating and cooling systems are closed systems the only way the windows fog is the coolant is hot and steams inside the car due to some leak inside the heater core box. as well as the smell being present. Now it is possible that a little leak has occured where the coolant supply or return line connects to the heater core and is running into the car which is running onto the core and creating steam and smell. hopefully it is a easy clamp tighten fix for you.

Car is overheating and windshield is fogging up


If your smelling coolant in cab, and window fogging up, check fog if green heater core is going. Over heating could be a couple of things, plugged radiator, water pump, thermostat. To check for water pump Find the top hose, run car check for leaks on ground. While warm or hot wear glove oven mitt or something that you can feel through but will protect from heat, If you feel flow of coolant more the just a trickle its a good thing to replace thermostat. Also check for bubbles in the coolant tank, if there are bubbles your S.O.L. the head gasket is blown
