    I have a 2000 Ford Explorer. In order to cool, I have to set the controls on
    MAX Cool otherwise it will blow hot air. Once the interior has cooled down
    it starts blowing hot air.

    I have a 2005 Ford Focus Wagon 2.0 and i have very high pressure on the low side of the air conditioning system, I got a can with a gauge on it to pump it cause the air don't seem to be very cold it seems warm, so i thought it was low on freon so when i put the gauge on it it was in the red on the gauge and it said on the can if it is in the red that i had a macancal problem the pressure was very high, does anyone know what will cause that?

    Anybody have an estimate to replace 1997 ford explorer thermostat? I assume that's the problem. Drove it from FL to NC...just fine. Now, it doesn't warm up (needle moves a hair, but never into normal temp range). Here it's about two degrees and, of course, I can't get hot air out of heater. Stuck thermostat? Valve?

    I have a 1997 Ford Explorer. In order to cool, I have to set the controls on MAX Cool otherwise it will blow hot air. The temparature knobs is loose but it has to be set to cool. I was told there is a termostat controler which is stuck but it under the engine compartment and will cost $300 to replace.

Get an ecu from the junkyard and replace it. Also try shorting out the pressure sensor with a jumper wire- it sits on top of the evac/drier. If the compressor comes on, replace it.

Why isn't the heat hot on my 1998 Ford explorer?


There a a couple of possibilities

1. The thermostat is stuck open. This can usually be veried by looking at the temp gauge. If it is not about half when after the engine has had enough time to fully warm up than I would suspect a bad thermostat.

2. the coolant level is too low. The highest point in the cooling system is the heater core. If the coolant level falls to low the heater core will not get enough hot coolant to function properly.

3, the heater core is plugged. Proper cooling system maintenance will remove much of the debris that ends up in the cooling system. If this service has been neglected this debris will settle in the heater core. Over time it will build up to the point that hot coolant can not flow through the entire heater core resulting in less than adequate or no heat.

4. The last possibility (and the least likely) is that you have a head gasket failure. The air that gets pushed into the cooling system will cause an air pocket in the heater core restricting the coolant from entering.

Codes p0128


A code P0128 may mean that one or more of the following has happened: Low engine coolant level Leaking or stuck open thermostat Faulty cooling fan (running too much) Faulty coolant temperature (ECT) sensor Faulty intake air temperature (IAT) sensor Possible Solutions Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code: Verify coolant strength & level Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary. Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary. Verify proper intake air temperature (IAT) sensor operation, replace if necessary. If the above items check out good, replace the thermostat

first check coolant level in radiator coolant level sound low.if coolant overflow jug empty.coolant sysyem low, when add coolant to coolant overflow jug coolant level should stay at full cold mark.if coolant level okay,engine overheat while sitting or moving in slow traffic either coolant fan relay or fuse could be bad.or engine coolant temperature sensor could be bad. coolant sensor turn on cooling fan at certain temperature.hot wire check to make sure cooling fan motor not bad or short in wires.if all is good have pcm check it controls fan relay to through the coolant temperature sensor signal when coolant get hot.

2002 eclipse heater blows cool air


Check your antifreeze level and if low then add antifreeze until the radiator is full and the overflow tank is up to the correct level. that should solve your problem. If it isn't that, chances are your thermostat could be stuck open which isn't allowing the coolant to warm up properly.

Good Luck

Coolant level low light comes on and coolant level is not low in reserve tank or radiator.


There is a TSB for this problem. Here it is.


Bulletin No.: 04-06-02-007

Date: August 11, 2004

TECHNICAL

Subject:
Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination)

Models:
2000-2002 Buick Century, Regal
2000-2001 Chevrolet Lumina
2000-2002 Chevrolet Impala, Monte Carlo
2000-2002 Pontiac Grand Prix
2000-2002 Oldsmobile Intrigue


Condition

Some customers may comment that the low engine coolant level indicator is always illuminated.


Cause

The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.


Correction

Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.


Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of "aftermarket" over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin.

1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL(R) mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin.

2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section.

3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light:


^ Light is on - Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI.

^ Light is out - Proceed to Step 4.



4. With the key off, connect the coolant level sensor into the vehicle's wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.


^ Light is on - Replace the low coolant sensor and re-check system operation.

^ Light is out - Proceed to Step 5.


5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Re-install the low coolant sensor into the vehicle and proceed to Step 6.

6. Flush the cooling system and install new DEX-COOL(R) mixture as outlined in the SI. Check the vehicle's warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination.

My 2003 ford focus is over heating quickly especially when i am sitting at a light, then when i turn the air conditioner on it overheats more


1. Does the cooling fan turn on when it over heats?
2. Check your coolant level, if it is a little low it will cool normally under transit and over heat in the conditions you are describing. Also have your coolant check for proper dilution.
3. If your cooling fan is failing to turn on you may have a coolant temperature switch issue.

Engine running to cool


Replace the thermostat. If thermo is stuck open, coolant only heats up when there is no flow over radiator(idle) and then cools down when driving. Also, check coolant level, same response as stuck thermo.

Only hot air blowing out of vents


i am a nissan master technition in Wichita Ks. we see this problem frequently. there is an air pocket in your heater core, due to low coolant level. for some resion or another your vehical is consuming coolant (usually head gkt leaking into cyl). and sence the heater core is higher than the radiator, the air pocket gets stuck in the heater core.
wait till the vehical is cooled off, remove radiator cap, install coolant funnel (avalible at any auto parts store). lift front of vehical off the ground (to get the radiator higher than the heater core), fill coolant funnel and start engine. allow vehical to reach opperating tempature and the air pocket will work its way loose. you may need to rev engine to change coolant flow rate in atempts to remove air pocket quicker.

sorry about the spelling
