Asked by Apr 29, 2018 at 11:00 PM about the 2007 Toyota Camry LE

Question type: Maintenance & Repair

My car is overheating with the a.c. on. The first day
it started,  the a.c kept blowing hot air. I checked
the temperature to see if it was overheating( didnt
overheat at the time ) until later that day it started
to overheat and leak out all the coolant . From
there I drove my car all the way home without the
a.c.. (didnt overheat when i did this ) We then
checked to see if there was a leak (tested with
water ) as I reaved up the engine the water
squirted out a streams of water at the top of the
resivor and water was leaking from the resivor.  
The engine wasn't overheating at the time cause
the a.c. was off.  The fans also dont work witj the
ac on . Could this be a fan relay ? Or what other

there is a TON of confusion here!! The first day it started?? The first day of what ...when you had bought the car or first day you got back from shop? you have an 07 Camry ( one of THEE finest cars on the sedan market). you don't say how long you have had the car or how long it sat, etc. When you are using the AC, it is best to have the moving down the road ( most AC's are designed for better operation while moving.. and not idling). It says you checked for a leak and tested with water??? What are testing?? y'gotta help me a little. There is NO way you tested the AC freon or the system with water because that is not how you test it. NOR, when you say it's leaking everywhere is that a problem. When an AC is running ( idling or in motion) a liquid is dripping down, yes, and this nothing to worry about. ANY vehicle that is running the AC and stand still you will see this. so what, it's nothing Also, if you rev up the motor to check your reservoir, and it's pushing out/ erupting water/ fluid / coolant, you have WAY too much in that little res tank. SOMEONE put too much in. that tank is used for the pressure to escape to when it's coming out of the block. The water pump will rotate the cooled down coolant out of the radiator into the block and so forth. This is exactly why you don't take off the radiator cap. there is an INTENSE amount of pressure under that cap.. this is why it is escaping into the little reservoir tank. DO NOT EVER USE JUST WATER IN YOUR COOLANT. WATER WILL TURN INTO A GAS BECAUSE IT WILL BOIL ( LIKE EGGS). WHEN IT BOILS IT GETS VERY HOT AND WILL NOT COOL DOWN. anti freeze will not boil because it's designed to with stand heat. I have a Ford and i can drain my little tank if I had someone put just water in it. I do not know if you can drain out a Camry res tank. I would definitely check that out. And yes, there is a relay for your fan. Check out your fuse ( it should be on your fuse panel or in your owners manual just where that fuse it. It will not tell you on a Ford ( it was a bad day going through all the fuses). I just rented a Camry last month, it's a fun car, just WONDERFUL driving. good luck

Wow you really are confused. I stated that my car was overheating . So i was referring to that specific issue when I said "the first day it started ". I've had the car for a year now. I'm aware water leaks from the a.c . When I stated I tested with water, I put water in the coolant resivor to test for any leaks in the cooling system . Therefore my car overheats with the a.c on , and the fans do not turn on. Also the resivor will leak liquid from the top . Could this just be the relay for the coolingfan or the thermostat? If so what pricing am I leaking at

My last question is me looking for a solution to fix the leaking and overheating


right, anyone would be confused. there is little facts in the complaint. don't call the cops. and pouring water in the res tank is NOT how you check a coolant problem. I'd recommend going back to school and taking a class or 2 on automobile basics and learning how they operate before asking for someone to help. Usually people learn they need to help themselves before asking for help. it's a good idea here.


Ok...the cutomers complaint seems to be an overheating problem. Lets see if we can help. Any warning lights on or flashing when the engine is running and the AC is on. See if that little AC indicator light is flashing. When the AC is turned on...do the cooling fans run?
