I just found out my water pump is going bad does that have anything to do with my ac not staying cold long?

(2010-05-30 13:38:35) 1. mickey Says: i just got a 2000 ford taurus when i got it i noticed the a/c blows cold air the first couple of minutes then it blows hot. i just found out that my water pump is going bad and the guy said there is a blockage in my a/c that is keeping the car from staying cool. are these issues tied together in some way. or am i being lied to. i know its my water pump cause we smelled burning antifreeze yesterday and the need quickly moves from cold to hot in less than 5 minutes. what things i can get done to my car to check it for the right thing without being more confused than i am now. and are they major repairs or minor.2. teddybearnumber1 Says: They can definetly be related. The fan clutch on my Ford Explorer wore out and was not turning the fan as fast as it should. My water temperature would sky-rocket in just about a mile or two. The A/C would work fine until the water temperature went up and then it would blow hot air. I replaced the Fan Clutch got rid of my overheating problem and have not had a single problem with the A/C since then.
If you are sure the water pump is going, then the water is not circulating fast enough to stay cool and it can effect the operation of the A/C.3. ken k Says: replace the w/pump and t stat/recharge the ac unit/ones got nothing to do with the other/blockage occurs if you eat too much cheese4. jacob f Says: that could be something other then your water pump...any chance you checked your coolant level?


a/c will switch off when the engine gets too warm


for the people who think otherwise, 90% of cars with ac have safeties that turn off the ac if the engine starts to overheat, why because the ac condenser is in front of the rad, it gets hot when the a/c is on. causes hotter air to hit the rad and the engine runs warmer, ac off, engine cools down... its a simple safety system...5. PGM Says: The water pump and AC are separate systems (both driven by belts from the engine).

You will likely have to replace the pump, if that is the problem.
AC blockage? I am not an AC tech, but it might just be low pressure. You can convert to the new coolant type and charge it yourself, if that is the case.6. Carter_k1 Says: No, I suggest you change your water pump and change the cambelt, tensioners etc. as well since the water pump is run by the cambelt belt (the cambelt makes sures that the engine works in harmony, that snaps an engine rebuild is in order) so if the water pump breaks there maybe a risk of the cambelt being broken.

As for the air conditioning, air conditioning needs to be re-gased every year, so you may want to take your car to a garage to have the air con checked to see if it needs to be regassed.7. Colanth Says: The A/C could be blocked, but it also could be undercharged, there could be air in the system and a few other possibilities.

Check out the water pump. Unlike you, if the engine gets too hot, you'll be buying a new one. But you could also have a thermostat that's stuck closed.

One has nothing to do with the other.8. the_boy_toy Says: How did you find out the water pump is going bad? The water pump and a/c have no relation. Turn on the car and the a/c. and look under the hood. Sometimes the condensor tends to sweat and the more it sweats it will look like the car has a leak. Yes you should charge up your a/c/9. Michael R Says: The water cooling system for the engine (radiator, water pump, hoses, etc.) is completely separate from the air conditioning system. The water pump moves water from the radiator (where the water is cooled off) to the engine where the water travels through tubes in the block, picking up heat (cooling the block) and then returns to the radiator. A failing water pump would not cause "burning antifreeze". It would cause overheating by not moving the water, or not moving it fast enough. The smell of antifreeze in the exhaust (a sweet smell) usually makes me think of a failed head gasket or a cracked block. The water is somehow getting into the combustion chambers from the tubes in the block. If the engine has been overheated it is not unusual for the head gasket to blow or for the block to be damaged.
Take your car to a reputable mechanic - not a buddy who works on his own car in the back yard. Ask friends and family who they go to and what they have experienced. There are good, honest mechanics out there. Find one and have him check out the car. Pay him for his training and experience. It will be cheaper in the long run than going to the cheaper guy working in his driveway.
