Heating AC and Engine Cooling

The Cooling Fans ( 1 Small & the a bit Larger ). The Big One Is For Cooling The Radiator For Normal Engine Usage. When The A/C Is On The Smaller Fan Will Run To Allow More Air To Be Pulled Over The Condensor And Radiator, To Better Cool The Water & Make The A/C More Efficent. There Is A Sensor In The Engine That Controls The Cooling Fan This May Have Gone Bad. I Would Begin My Testing Here First. Then Test The Fan To See If It Is OK. Hope This Helps

You can buy a replacement hose at an auto parts store. Or, if your heater core is bad and you are not replacing it, you can disconnect the other hose from the core and reroute it back to the intake to keep the water circulating through the engine.

Special tool required to open lines - once system is exposed to the atmosphere, it will have to be evacuated prior to re-charging. Good job for the professional

See this video on youtube for help with changing your cabin filter on your CRV.

Please post up any difficulties you had in following these directions or tips on how to make it easier. Thanks.

Three on the left, three on the right, two on the rear of the block.

Front of the firewall, on the passenger side. It's mounted on a cover which has a generally half cylindrical shape.

You must first remove the serpentine drive belt.

You must remove the two devices that sit on top and rearward of the PS pump. One is the Cruise control unit and the other box is electrical in nature.

then you must remove the one bolt in the back side of the pump that is attached to a bracket and the three bolts on the front side of the pump that attaches it to the bracket. You must remove the front three by using the holes in the pulley. The bolt on the back side is not easy to get to and you may need to unbolt another bracket to get to it.

Suck out all the PS fluid and remove both the PS pump lines, one with line wrench and one with clip on rubber hose.

You may also want to remove the molded plastic air intake by loosening small bolt holding it to the intake manifold on the back side.

At that point the PS pump can be rotated around to be removed. This requires some patience and some unique moving the PS pump. But it will come out.

Get the pump with the reservoir already on it. More $ but less trouble and mess.

Hope this helps. Just did it a month ago on my sons's 2002 Cavalier. Was pretty easy compared to other jobs I have done.

Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.

Is the fan stuck on or is it just hot air even with the a/c on???

I'm betting your local Caddy dealer had one. Other than that a good quality auto parts store has, or can order for you, a service manual.

If you are talking about the HVAC blower motor then it is mounted on the firewall behind you glove box on the passenger side. Just remove all the lower dash trim and you will see two large black boxes your blower motor is in one of those, I believe it is the one on the right.

Defective heater resistor pack.

Owner's manual.

There are two valves on the air conditioner on a 2000 Pontiac Bonneville. Attach the hose that fits the refrigerant and fill that side.

Sticking out of the firewall on the passenger side of the engine compartment or just below.

You can. It may not do as much good as you're expecting, and you could have a time trying to fit the second one in.

Hi,

The cabin air filters (there are two) are located behind the cover at the BACK of the glove compartment. I have added a link that shows their location and a step-by-step procedure to replace them.

Good Luck, Greg

You have to remove the glove-box. You will find the relay back - to left.

No, if a fuse were to overheat it would blow. A shorted circuit can cause a fuse to blow.

Yes. If the fuse for the electric cooling fan should blow, then the fan will not turn on and remove heat from the radiator at low speeds. At higher speeds, there will be enough air movement to cool the radiator.

Also if your experiencing problems with your car overheating you should look into other causes, such as making sure your anti freeze reservoir is full

Do you have a heat pump or Gas Furnace?

With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!

This is one of Toyota's dirty little secrets! The '98 Toyota Avalon was sold with a known defective A/C Amplifier. They issued a Technical Service Bulletin on December 3, 1999 #AC005-99 on this exact defect. = A/C int. INOP = Ambient Temperature light INOP = Fresh/Recirc Light INOP = Mode Indicator Light INOP = Blower INOP Toyota put a footnote on the TSB that "Warranty application is limited to correction of a problem based upon a customer's specific complaint." Which means the service department will not tell you about the problem. You have to be a expert and tell them what the problem is. The biggest scam is that this is an intermittent problem and unless it is not working when you bring it in they will tell you they can't duplicate the concern. Shame, shame, shame on Totota! The fix is a new A/C Amplifier, new Inlet Servo Motor, and new Servo Link. All told, including labor, this will cost you over $1,000 Of course, now that you know what the cause of the problem is... they will deny the fix because the vehicle is out of warranty. Many of us have been down this road! Just remember who screwed you next time you go to buy a car.

read up on the system Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave

The only way to drain all the coolant is to unhook the bottom radiator hose. The radiator does NOT have a drain vale.
