I had similar problem until the car was is Kazeemed! Eventually I was told to buy a new evaporator and condenser, I just kuku ignore using A.C. |

I had a similar experience. The solution I deployed is that I removed the radiator and washed the interior with a special Chemical/detergent. Then my car came back to status quo. Most flushing done by car wash or whatever is not usually effective. Please try rewashing your radiator. |

AutoElectNG: U NAILED IT, but sadly he and his army of mechanics wont understand or care, all they care is install double radiator, remove therstat and all sorts of rubbish, what you explained above is the correct resolution of his probs |

I also experienced this,just change ur radiator to a double cell. |
Re: My Toyota Corolla Over Heats Only When The AC Is On! by earthrealm(m): 1:46pm On Oct 04, 2017 |
safari0412: THIS SADLY even though it may solve the problem, will undercool the car!!!. a car is designed to run at an optimum operating tempreture of btw 85 to 95deg celcuis...wch corresponds to the middle of the temp guage on the dashboard. any other gimmick or contraption you are doing which includes but is not limited to installing double cell radiator/ double fans/ ordinary water/ having the fans running continously once the car is switched on etc....will introduce the issue of undercooling to the engine. this carries its own hidden wahala.....though una probablly wont/dont understand.,,,its just that unlike overheating, undercooling is a silent killer..and may take 3 to 5 yrs to wreak the engine, it causes higher fuel consumption, deposition of soot/carboon inside the engine, formation of sludge etc 2 Likes |

Which country's corolla are we talking about here? US/Japan/South Africa? 6. Does the vehicle happen not overheat even if the a/c is on PROVIDED THAT you are in freeway traffic as opposed to stop and go traffic? *The vehicle doesn't overhear at all, if the a/c is not on. No matter the type of traffic* I know that without A/C no overheating I want to establish if 1. A/C is ON and 2. You are driving at speeds of 100 km or more (aka freeway traffic) for extended periods of time it still overheats? Please run the test and revert Finally, seems you just got the ride, and you attempted to upgrade it with A/C when this happened. 1 Like |

@Op buying a double cell radiator, double fan and removing the thermostat is not the absolute solution for your problem as this might cause your engine to run cold which will damage your engine. Do a proper diagnosis on the following:- 1. Check if your thermostat is still working or if you actually have one. If your car is running without a thermostat please do yourself a favor and get one and the appropriate one. 2. Check the functionality of your water pump (the internal blades and for corrosion etc). 3. As suggested by others check the direction of air flow of your fan and it's speed. 4. Make sure that you have a specialist check your electrical connections and revert all wiring to factory specs and also check your ECU and other sensors. 5. Check for Toyota's recommended coolants and mixing ratio with distilled water (65:35 or 60:40 of distilled water:coolant) for hotter regions like Nigeria. 6. Check for lickages and reflush your radiator with the appropriate chemicals and check for sludge build up. 7. Finally, do a proper diagnosis on your cooling system like the evaporator, dryer, compressor etc. Reverting from factory specs is a bad practice that Nigerians love to do and that's why most people don't like buying Nigeria used cars due to abuse. If your car came with single cell radiator and fan kindly leave it like that and look for the cause(s) of the overheating, as using or going out of spec might result to one or more cylinders misfiring, engine wear and tear etc. Hope to see how you got it solved and the cause(s) of the problem. 1 Like |

[quote author=Egji post=61181150][/quote] Please how did you resolve this issue. I am having the exact problem. Its giving me sleepless nights as it is. Removed thermostat, changed radiator and recently even replaced gasket. Would be looking forward to your reply |

elebiola: Did you change radiator to a new exact car spec? |
Re: My Toyota Corolla Over Heats Only When The AC Is On! by elebiola(m): 8:41pm On Dec 11, 2018 |
ojeysky: Yes I did, I changed it today double cell radiator. Brand new. Not like the car overheats but the temperature gauge rises above the middle line while using the Ac in traffic and immediately i switch it off, it comes down. |

Try changing your coolant temperature sensor elebiola: |
Re: My Toyota Corolla Over Heats Only When The AC Is On! by elebiola(m): 11:29pm On Dec 12, 2018 |
Thanks, I would try that, please do you have an idea of price? homeboy205: |

Re: My Toyota Corolla Over Heats Only When The AC Is On! by ojeysky(m): 6:45am On Dec 14, 2018 |
elebiola: I hope it was double cell that is the actual specification of the car, my car had a single cell and changing it to single cell was all I did. So how is the performance after the change? By the way you may want to check your coolant as well, if you can't afford the original Toyota coolant don't go for the Abros rather go for distilled water instead. |

Have you solved the problem? I'm not experiencing the same case. In addition the slow goes to below 1 and the car off itself. Corolla 2012 spot |

Nbg4real: For yours, I'd advise that you scan and post codes here. |
