Water pumps usually leak when corrosion has already degraded the pump. Air entering the cooling system from the leak can accelerate corrosion. Corrosion and damage can be caused by the following conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Using the wrong type of coolant<\/li>\n\n\n\n<li>An incorrect ratio of the coolant and water mixture<\/li>\n\n\n\n<li>Using tap water instead of distilled water in the coolant mixture<\/li>\n\n\n\n<li>Cooling system restrictions or cavitation<\/li>\n<\/ul>\n\n\n\n<p>Once the coolant becomes corrosive, it can cause the water pump gasket to deteriorate and leak. Water pumps can also leak from the shaft seal. Shaft seal failure can occur from the following conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Age<\/li>\n\n\n\n<li>Vibration<\/li>\n\n\n\n<li>Low coolant<\/li>\n\n\n\n<li>Worn bearings<\/li>\n<\/ul>\n\n\n\n<p>For more in-depth information about how and why water pumps fail, check out these informative blog posts <a href=\"\/blog\/water-pump-failure-causes\/\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a> and <a href=\"\/blog\/explain-water-pump-failure\/\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why You Should Never Replace A Water Pump Gasket Alone<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket.jpeg\" alt=\"\" class=\"wp-image-30728\" srcset=\"https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket.jpeg 500w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket-450x450.jpeg 450w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket-150x150.jpeg 150w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket-300x300.jpeg 300w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/water-pump-gasket-100x100.jpeg 100w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/figure>\n\n\n\n<p>It is possible a water pump gasket can leak prior to a water pump failure. However, it\u2019s never a good idea to replace only the gasket. As described, the pump may already be failing by the time the gasket leaks. It can also be difficult to diagnose if the pump is only leaking from the gasket, the shaft seal, or both.<\/p>\n\n\n\n<p>Most water pumps are a labor-intensive repair. They may require a lot of disassembly to access, especially if they\u2019re driven by the timing belt. In most cases, the labor cost alone is substantially more than the cost of a water pump. This is another reason why you should always replace the water pump and gasket together. Even if you do the repair yourself, chances are you won\u2019t want to have to do it again when you thought only the gasket was bad.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why You Should Never Reuse A Water Pump Gasket<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"572\" src=\"https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/gasket.jpeg\" alt=\"\" class=\"wp-image-30729\" srcset=\"https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/gasket.jpeg 640w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/gasket-450x402.jpeg 450w, https:\/\/gmb.net\/wp-content\/uploads\/2022\/06\/gasket-600x536.jpeg 600w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption class=\"wp-element-caption\"><em>Image Credit: <a href=\"https:\/\/mechanics.stackexchange.com\/questions\/38332\/reusing-a-metal-water-pump-gasket\" target=\"_blank\" rel=\"noreferrer noopener\">MechanicsExchange<\/a><\/em><\/figcaption><\/figure>\n\n\n\n<p>Water pump gaskets can be made of different materials. Depending on the water pump design, gaskets can be made of paper, RTV silicone, or metal. Under no circumstances should a water pump gasket ever be reused. Water pump gaskets must maintain a seal under high temperature and pressure. Paper and RTV gaskets will be damaged upon removal of the water pump. The old gasket material will need to be thoroughly scraped and cleaned from the water pump mounting surface. Metal water pump gaskets may appear reusable. However, the crush seal bonded to the metal is designed to be used only once. Reusing a metal gasket can result in immediate failure.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"GMB Replace Water Pump Time Belt Together\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/B79OXVhnBiA?feature=oembed&#038;modestbranding=1&#038;rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Save time, money, and headaches by always replacing the water pump and gasket (and likely the timing belt, too) together.
