Given the reputation of Lexus, you'd figure the Lexus heater core was of incomparable quality, right? Well, sort of. You see, no matter how good the Lexus heater core is from the factory, it relies on some basic maintenance practices in order to do its job over the long haul. Changing the coolant in your Lexus helps the Lexus heater core out a lot, but it's one of the jobs that people often neglect or put off. So, even though the Lexus heater core is well-built, years of corrosion and buildup from old coolant ends up creating leaks and blockages inside the Lexus heater core. That's no good, because you've probably noticed how nice the carpet and upholstery is inside your LS or ES. Throw a little coolant from a leaking Lexus heater core into the mix, and it's a nasty recipe. Not only does the leaky Lexus heater core stain your carpets and seats, but it can also corrode electrical connections under the dash and cause rust to start forming on your floorpans. While not quite as damaging, a plugged up Lexus heater core can cause a reduction in heat output in your HVAC system and eventually lead to leaks due to the increase in system pressure. Of course, if you're reading this now, you're probably wishing you had this advice about flushing your Lexus heater core about four years ago. Unfortunately, you're holding a piece of Swiss cheese that used to be a Lexus heater core, so a coolant flush isn't going to do you a lot of good right now. You need a premium quality new Lexus heater core, and we can supply it for way less than the dealership will charge. So order your new Lexus heater core right now and you'll be rewarded with lots of heat and a nice, dry interior to get you through winter.
