Does the water pump effect the car AC?

Question

my nissan 1993 maxima SE
the AC is not cold at all this year
it ran perfect the year before
can the water pump pressure really affect the AC?
how much should a new water pump cost for my car?

Answer 1

It won't effect it to the point that your a/c isn't cooling down. Your water pump and compressor for the a/c are run by the same belt. If your water pump goes, you will loose power steering, a/c, and you will have a major coolant leak. If your water pump HASN'T blown and your a/c doesn't work, then it is a seperate issue. (WHICH IS WHAT IS WRONG WITH YOUR CAR!) You will have to get your vehicle switched over to R-134a because you can no longer use freon or R-12 in your vehicle for the a/c. You might be lucky and not have to switch anything over becase they started using R-134a in 1992 and by 1994 all cars use it. Take it to a shop, they can pressure check it...you might have a leak somewhere in the condensor or evaporator. A new condensor should cost around $150 and a new evaporator should cost between $500 and $1200.

If you have R-134a your mechanic should pressure test your sytem. If he doesn't find a leak, then he should fill up your a/c with R-134a and stopleak with dye. Drive it for a few weeks and if you notice an increase in temp then you have a leak in your condensor or evaporator. Either take it back to the shop to get those parts replaced or check out this website provided below and purchase a can of R-134a Super Seal. That repairs leaks in rubber or metal parts of your a/c system...and it works great. 1 bottle of that stuff should cost you right around $25 and it really does work. If you are handy, then research fixing your a/c yourself. You will save tons of money if you do it yourself...and after you get the stuff, it will only take you a few minutes to fix. Buy R-134a at a local auto shop or off of ebay, buy a hose that hooks up to the low-pressure valve, and fix it yourself.

OK, do it yourself instructions...

you will need:

-at least 2 (12 oz) cans of R-134a refrigerant
-hose with piercing stem that attaches to R-134a can and to your low-side service port (never connect to your hi-side service port)
-1 can of Super Seal (comes with basic hose...not with psi gauge)
-gloves, long sleeves, pants, (you want to keep covered just in case)

Directions:

1. Locate low side service port.
2. Turn on vehicle and set a/c to max cool.
3. Attach hose to can of Super Seal...make sure piercing stem is in up position to make sure you don't accidentally pierce can.
4. Attach other end of hose to low-side service port.
5. Puncture can and hold upside down until can is empty or for about 2-3 minutes.
6. Detach hose from low-side service port and then from can of Super Seal.
7. Attach hose to can of R-134a refrigerant and then to low-side service port.
8. Pierce can and hold upright because you only want the gas to enter the a/c system. While doing this, lightly shake can from side to side. Can will become hard and cold...that is normal.
9. Allow sufficient time for can to empty...could take between 5-10 minutes.
10. Detach can from low-side service port and then from can.
11. Add more R-134a if necessary.
12. Let vehicle run or drive it around for 15 minutes to get Super Seal through system.

Remember...adding too much or too little R-134a will not make your a/c system run properly. Your car is rated at a certain psi or pound...find that out and look into getting a hose that has a gauge on it. Also, take note of the outside temp...if it is warmer out, your car will give a higher psi reading. If it is cooler, it will give a lower reading.

Do some research...look around...it really isn't that hard to do. And just think of the money you will save.

Answer 2

Ac Water Pump

Answer 3

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.

Answer 4

It sounds like you have a leak in the AC system and are low on freon. The low pressure switch is cutting off the compressor to keep the system from freeaing up and damaging the whole system.

The water pump has no connection at all with the AC system.

Call a Nissan dealer and ask for an estimate on the water pump job. Also call some places like autozone and see what a new water pump would cost there. good luck.

Answer 5

You must know water pump is for cooling your motor ,by moving water around inside , AC has a pump or a compressor , Inside is a gas , under pressure the gas get cold when the cold lines are put in a space with a fan it makes cool air for you inside your car!!! All you may need is some more cooling gas for your AC pump

Answer 6

not even close. Have the mechanic put some gages on your ac system and check the pressures. He will be able to tell you if it needs a charge and where the leak is that needs to be fixed first. Good Luck

Answer 7

No, the water pump has nothing to do with the A/C. Your system sprang a leak and lost all the refrigerant. Take it to a shop and have it checked.

Answer 8

water pump no more than 150 and if ur ac isnt blowing cold then u need free on

Answer 9

Water pump has no affect on a/c. Find a new mechanic.

Answer 10

NO , If your A/C is not cooling try adding a can of R134 and see if it gets cooler if so you know the system is low add one More can good luck stay cool
