Re: 2001 Audi A4 2.8 no or little heat

Thank you for your advise; I was thinking abot this valve but I couldn't find it. Is it inside the hose that goes to the heater core? Can I just buy a new one from an online store? Searching the internet did not help (for part, position or schematic). I would just replace part if I would now how to find it or how it looks.

    I did more digging plus I called dealer and it looks that my car does not have a heater valve (2001 A4). At this point in time I think that I might deal with a partially plugged heater core (I get ony a small stream of coolant @ heater core return). I checked today and the inlet hose to the core was hot and the return only luke warm. I'd like to find a good way of unplugging the core.

Where is the heater control valve on a 2005 Buick Lacrosse?


It sounds like the heater control valve may be stuck. This valve allows heated water from the engine to pass through the heater core which in turn heats the inside of your car. If this valve is stuck, only a small portion of heated water will pass through. If this is the case, you should have the control valve replace.

You should be able to find it by following the heater hoses coming from the radiator leading back to the firewall. These hoses will about 1/2 - 3/4 of an inch in diameter so you shouldn't get them confused with the normal radiator hoses.

You can probably purchase a new valve at an auto parts store but I'm sure the dealer will have one.

If that's not the problem, it could be that the core itself is clogged up. That's a little more expensive and more of a pain to replace. if this is helpful please dont forget to give rateing thank you

I HAVE A 2000 AUDI A4 , THE HEATER CORE BLEW, IS THERE A WAY TO CLIP THE HOSE OFF SAFELY DRIVE IT TO A MECHANIC.


If you can cut the heater hoses off from the heater core at the fire-wall, and then use a piece of pipe or a hose adapter and hose clamps to join or connect the two heater hoses together, then you can actually drive the vehicle until you require heat from the heater core inside the passenger compartment of the vehicle.

I have a 2001 Audi Quattro 2.8 and my heater is blowing out cold air how can I fix this problem?


The cardboard in front of the radiator is only good if the problem is an open thermostat. If the problem is a bad heater control valve, then blocking the radiator could over heat the engine. I suggest comparing how hot the radiator hose feels, as compared to the heater hose. Watch the heater valve when you operate the control knob, to see if it is opening and closing properly.

Heating doesnt work 2001 Audi 2.8l a4


Sounds like the water level is low. Often the water pipes are higher than the radiator and require bleeding when the car is running, see if there are any bleed screws on the hoses to release the air.
