But if it gets closer to the H level, there might be a radiator problem to blame.<\/p>\n\n\n\n<p><strong>A common issue with Toyota Corolla radiators is overheating due to a clogged radiator. Debris and sediment can accumulate, preventing proper coolant flow and heat exchange. The solution is straightforward: flush the radiator system to remove the blockage, ensuring effective cooling and operation.<\/strong><\/p>\n\n\n\n<p>Another potential cause for Toyota Corolla radiator problems is a malfunctioning thermostat. The thermostat regulates coolant flow, and if it&rsquo;s stuck, it can lead to overheating. The fix here is to replace the faulty thermostat. A new thermostat will ensure proper coolant circulation, keeping the engine at the optimal temperature.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva.jpg\" alt=\"Hand opening radiator cap\" class=\"wp-image-1058\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"640\" height=\"427\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20640%20427'%3E%3Crect%20width='640'%20height='427'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"Hand opening radiator cap\" class=\"wp-image-1058 eager-load\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva.jpg\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva.jpg.webp\" data-srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-1-canva-300x200.jpg.webp 300w\" data-svg=\"1\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>A third issue could be a leak in the radiator itself. Even a small crack or hole can lead to coolant loss, resulting in the engine overheating. The solution is to locate the leak and repair it. Depending on the severity, this might involve patching up the radiator or, in more serious cases, replacing it entirely. This fix restores the integrity of the cooling system, preventing further coolant loss and overheating issues.<\/p>\n\n\n\n<p>How do you diagnose and troubleshoot radiator problems in your Toyota Corolla?

The thing with radiator leaks is that they&rsquo;re pretty easy to detect: if you let your car idle for some time, you&rsquo;ll see a puddle right under where your radiator is.<\/p>\n\n\n\n<p>However, be careful not to confuse it with leaks from other components, such as the water pump, thermostat housing, or hose. If these are the parts leaking, the puddle would most likely appear under the engine.<\/p>\n\n\n\n<p>Another telltale sign of a leaking radiator is when your car overheats. So be sure to monitor your coolant level and temperature gauge to avoid overheating.<\/p>\n\n\n\n<p>Another symptom of a radiator leak is a squealing belt. The leak could spill coolant onto the belt, which can slow down the accessories of your engine. There&rsquo;s also the white smoke that can come from under the hood, even if the car isn&rsquo;t overheating. This white smoke stems from the coolant that gets into the exhaust or the hot engine.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How To Fix a Toyota Corolla Radiator Leak<\/h3>\n\n\n\n<p>For smaller leaks, there are stop leak products that you can use.

A radiator hose can wear out for two reasons: time or oil leaks. These situations could make the hose swell or crack.<\/p>\n\n\n\n<p>Driving with a leaking radiator hose can easily lead to overheating. You can buy a replacement radiator hose for less than $25. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Toyota Corolla Radiator Fan Not Working<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva.jpg\" alt=\"Car radiator fan\" class=\"wp-image-1062\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva.jpg 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva-300x200.jpg 300w\" sizes=\"(max-width: 640px) 100vw, 640px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"427\" src=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva.jpg.webp\" alt=\"Car radiator fan\" class=\"wp-image-1062 lazyload\" srcset=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva.jpg.webp 640w, https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva-300x200.jpg.webp 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" data-pin-media=\"https:\/\/knowmyauto.com\/wp-content\/uploads\/2021\/05\/KMA-Toyota-Corolla-Radiator-Problem-5-canva.jpg\" id=\"mv-trellis-img-5\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>The radiator fan helps keep your engine cooler, even when it&rsquo;s been running for a long time. When it stops working, it might lead to your car overheating or running into problems when the radiator isn&rsquo;t working correctly. How do you know if the radiator fan isn&rsquo;t working?<\/p>\n\n\n\n<ul><li>When the AC is on at the second setting, you can see that at least one of the fans isn&rsquo;t spinning.<\/li><li>When the car has been running for a while with the AC off, even when the engine is hot enough, at least one of the fans isn&rsquo;t running.<\/li><\/ul>\n\n\n\n<p>There are a few reasons why your radiator fan isn&rsquo;t working as it should. Locating the problem is key to solving it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Electrical Problems<\/h3>\n\n\n\n<p>Check the fuse of your Toyota Corolla&rsquo;s radiator fan. If it&rsquo;s blown, replace it. But you have to locate the fuses first because they could be in a different place, depending on your Toyota Corolla&rsquo;s model.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Checking the Cooling Fan Temperature Switch<\/h3>\n\n\n\n<p>The location of this switch varies depending on your Toyota Corolla model year, so be sure to check your user manual to find out where it is.<\/p><p><i>Copyright protected article by Know My Auto and was first published on May 20, 2021. .<\/i><\/p>\n\n\n\n<p>Using a test light you can check on the temperature switch. Connect the test light to the battery ground and then start your engine. Let it idle and back probe the connector terminals of the switch using the test light.<\/p>\n\n\n\n<p>One of these terminals will trigger the light. Wait for the engine to get to operating temperature and then back probe the other wire that didn&rsquo;t light up.<\/p>\n\n\n\n<p>If the other terminal didn&rsquo;t trigger the test light, then the switch is faulty.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Checking for Short Circuits<\/h3>\n\n\n\n<p>When the fans blow out the fuses regularly, then there might be a short circuit between the fan and the relay. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Checking the Coolant Temperature Sensor<\/h3>\n\n\n\n<p>There are five symptoms of a faulty temperature sensor.

So there&rsquo;s a problem when the fan starts running the moment you turn the engine on or while it&rsquo;s still cold.<\/p>\n\n\n\n<p>There are several possible culprits behind this: a broken temperature sensor or a faulty relay. First, check the relay by swapping out the fan relay with another one you can find in your Corolla&rsquo;s engine.<\/p>\n\n\n\n<p>If that doesn&rsquo;t solve the problem, check the temperature sensor.<\/p><p><i>The copyright owner of this article is Knowmyauto.com and was first published on May 20, 2021..<\/i><\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Related Articles<\/h1>\n\n\n\n<p><a href=\"https:\/\/knowmyauto.com\/toyota-corolla-starter-not-engaging-0051\/\" data-wpel-link=\"internal\">Toyota Corolla Starter Not Engaging<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/knowmyauto.com\/toyota-corolla-alarm-not-working-going-off-randomly-0051\/\" data-wpel-link=\"internal\">Toyota Corolla Alarm Not Working\/Going Off Randomly<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/knowmyauto.com\/toyota-corolla-keeps-stalling-0051\/\" data-wpel-link=\"internal\">Toyota Corolla Keeps Stalling<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/knowmyauto.com\/toyota-corolla-power-steering-not-working-0051\/\" data-wpel-link=\"internal\">Toyota Corolla Power Steering Not Working<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/knowmyauto.com\/toyota-corolla-fuel-pump-issues-0051\/\" data-wpel-link=\"internal\">Toyota Corolla Fuel Pump Issues<\/a><\/p><p><i>KnowMyAuto is the sole owner of this article was published on May 20, 2021 and last updated on <time itemprop=\"dateModified\" datetime=\"2024-01-14\">Jan 14, 2024<\/time> .<\/i><\/p>\n\n\n<p>&nbsp; &nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Your Toyota Corolla&rsquo;s engine should always remain at the correct temperature when you&rsquo;re driving, about halfway between C and H.
