2000 Beetle. AC Airflow problem at different driving speeds. Crazy, huh?


sounds like at hi speeds the air is blowing over the intake below the wipers. because the shape of your hood it makes the air go over the intake. check your cabin airfilter, it may be clogged. if it has one it will be behind the glove box

Truck ran hot after a couple hundred miles. ran cooler at freeway speeds, still hotter than normal ( 240-250) . replaced fan clutch and drove to mexico in july with no problems, but is starting to do it...


Physically look in the radiator under the cap when cool, for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, try backflushing it, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it's loose, airflow can actually push it out of place making it useless or blocking the airflow. Along with that, there may also be a plastic piece attached to the bottom of, and wraps up behind the bumper. If it's loose, airflow can actually push it out of place blocking the airflow. Simply reattach it with 4 or 5 screws.

Also, if the vehicle has A/C and electric fans, one fan is dedicated to the A/C and should come on almost the instant the A/C is turned on. The engine fan will run even with the key off, that is normal. The system is trying to cool itself. Hope this helps.

Hello I have a Hyundai Tiburon 2003 v6gt. My car started overheating when I drove on freeway at 65 mph at 3.5 rpm and also when I'm on acceleration. I brought it to Hyundai dealer then they say my...


You said 65 mph @ 3500 rpm's? The rpm's are too high for that speed. Now, I do not know the drivetrain in a Hyundai, but any GM or Ford will run 65 mph @ 2500 rpm's. Are you sure you are putting the transmission in "D" and not "3"? "D" will be the third click from "P". If you are sure then try this:

My truck is running cold on the freeway but when I slow down and stop it starts to heat up a little. I changed the thermostat and am going to change the heater core could it be something else


yes could be problem with the radiator fan(s) not running at any road speed. Check the fan(s) for noise-free turning by hand. Check fan fuse and relay (swap with similar relay). Turn on the air conditioner which should immediately turn on the fan(s). Overheating while driving could very well be the thermostat--you will need to drain the cooling system before replacing the unit. Blow out the radiator core with compressed air from the engine side to remove bugs and other debris first. Hope this helps!

Heater dump valve, causing car to over-heat when heat is on


To properly diagnose your overheating problem we need to rule out some things.
First: Is there enough coolant/antifreeze in the radiator? Don't just look inside the plastic overflow bottle, but remove the radiator cap (when the engine is cold) and look inside the radiator. You should be able to physically see the fluid level if it is at its proper level. Most cars and trucks will hold 1 1/2-2 gallons of coolant and water mixture. If you have to add more than a pint of fluid you should have the cooling system pressure tested for a leak. If you see any obvious fluid loss on the ground or in the engine compartment, you should also have the system tested for leaks.
Second: If no coolant leak or low fluid level is present, then determine when the overheating complaint occurs.
If the engine overheats while at a stop or idle only:
Most front wheel drive cars use an electric cooling fan motor located in front or behind the radiator. The function of the cooling fan is to improve airflow across the radiator at stops and low speeds. The fan is controlled by sensors that regulate the engine temperature and additional load that might be placed on the engine.
The air conditioning compressor will require the cooling fan to operate at idle as long as the compressor is on. A quick way to check the cooling fan operation is to turn on the air conditioner. The cooling fan should come on with the air conditioner compressor. Some cars will have two electric fans, one is for the radiator and the other is the air conditioner condenser fan. Usually the radiator fan is closer to the middle of the radiator. The radiator fan is responsible for engine cooling, and the condenser fan is responsible for increasing air conditioning efficiency at idle and low speed.
If your vehicle does not have an electric cooling fan on the radiator it will have a belt driven fan blade and fan clutch. This fan should be pulling a large amount of warm to hot air across the radiator onto the engine. What you want to determine with either fan situation is that there is ample airflow across the radiator at idle. The radiator is the primary heat exchange for the engine, and airflow is crucial.
What if the engine overheats while at high speeds on the freeway?
Again, airflow and coolant circulation are crucial. At 55 MPH we can assume you have ample airflow across the radiator, so proper antifreeze circulation is the thing to inspect. I compare overheating at 55MPH to jogging with a sock in your mouth. The faster and longer you jog, the more air you are going to require, and with a sock in your mouth you are going to have to breath extra hard to maintain the proper amount of air to keep you going. At 55MPH the water pump is pumping a large amount of hot antifreeze throughout the cooling system.
If there is a restriction in the system like a kinked radiator hose, a restricted radiator, or a stuck thermostat, it will produce the same affect as the sock in the mouth scenario. Rust and water calcification can accumulate in the radiator and drastically reduce the flow of coolant at high speeds. Removing the radiator from the vehicle for disassembly and cleaning or radiator replacement are the only two real cures for a clogged radiator.
Using a can of "radiator flush" additive might help as preventive maintenance, but will probably just be a waste of time and money trying to correct a restricted radiator.

Hope this helps, best regards.

My heater stoped blowing hot air.antifreeze level


If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,

2001 tahoe front heater not working, rear heater blows warm air


I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?
