If you own a car, you probably know that regular maintenance is crucial to keep it running smoothly and reliably. You probably know when to rotate your tires and hopefully remember to get those oil changes. If you’ve forgotten to change your coolant for a while, look for these four signs. Bring your car in to flush the system before the problems get worse.
1. Warning Lights
Car manufacturers know how easy it is to forget maintenance and how difficult it will be to fix your car if your engine overheats too much. Your dashboard should have lights and warnings that come on when your engine overheats, which will mean that your coolant is low or old and not working well.
If your engine temperature runs higher or lower than it should, you should also take a look at your antifreeze levels. Whether the temperature trouble is related to your coolant, or another engine problem like the radiator or fan, you need to get to a mechanic as soon as you can to avoid irreparable damage.
2. Unusual Smells
You may notice a sweet scent when you fill or flush your cooling system. Remember what that smells like because if you can smell it as you’re driving, you’re probably overdue for a change. If you can smell the antifreeze, your coolant system has likely sprung a leak somewhere along the line and won’t hold the fluids for much longer. Take your car to the shop before the engine starts having trouble.
When you bring your car in to flush it out, have your mechanic check the rest of the system for leaks, as well as the engine for damage caused by overheating. The cost you have to pay for repairs will be far less than what you’d pay if your engine overheats for prolonged lengths of time.
3. Turnover Trouble
You might have trouble starting your vehicle in the winter if your area gets extremely cold, or if you live in a place that experiences extreme summer heat. If you try to use your car one morning only to find it won’t start, check the coolant before looking to other, more expensive fixes.
If you eventually get the car to start, keep an eye on the overflow reservoir over the next few days and see if the level fluctuates. If it does, bring your vehicle to the mechanic and have it flushed so your engine can get back to functioning at full capacity.
4. Color Changes
Colors aren’t the most reliable way to see if your antifreeze has expired. However, the shade of the liquid can be a good indication that you’ll need to investigate further. If the fluid looks rusty or has specks floating in it, the coolant has probably outlived its usefulness, and you’ll have to flush the system.
