Causes for Burning Rubber Smell in Your Car?
The following problems would be the main reason why your vehicle produces burning rubber odor:
1. Drive belt melting
If any drive accessories in your cars such as air pump, alternator, AC compressor, or water pump is locked up, the drive belt would rotate on the frozen wheel and produce a smell of burnt rubber. This problem is often accompanied by the squealing sound.
Solution: You need to replace this defective drive belt, and check the remaining ones. It is strongly suggested to check your drive belts for every 6 months to make sure the right operation.
2. Lose hosepipe
If one of the rubber hosepipes under the car’s hood is loose and exposed to any hot components of the engine, you would notice the smell of burning rubber.
Solution: Take the hosepipe off before it completely melts.
3. Stuck plastic bag
When there are any shopping bags stuck to your car’s exhaust pipe by accident and slowly burns away or melts, it would lead to a smell of burning rubber.
Solution: Carefully get rid of this plastic bag from under the vehicle. While driving, try not to make any contact with plastic bag flying around or lying on the road as it would get caught under the car easily and result in a long-term problem.
4. Oil leakage
Another cause for this problem could be the leakage of motor oil on the hot exhaust, which would lead to a dangerous situation when it burns and makes a fire.
Solution: Stop and jack your vehicle immediately. Get down under to determine the location of oil leakage. Otherwise, have it checked by a professional mechanic. If you keep driving with this leakage, it would result in more damage and cost you a lot of money for repairing in the future. Therefore, oil leakage problem needs to be solved as soon as possible.
5. Electrical issues
Short circuit or the blowing of the fuse would also cause the burning rubber odor in your vehicle.
Solution: Check for any blown fuses in all the fuse and cable links. Once you find out the problem, replace the fuse with a version that has the same part number in the owner’s manual.
6. Coolant leak
This problem would be also the result of leaking coolant in the air conditioning or heating system. As a result, it would lead to significant loss of coolant and serious damage to the vehicle.
Solution: Check for any cracks in the coolant tank of your car. These cracks would be small, but very dangerous and require a lot of money for repairing.
7. Oil leakage from the seal of the gasket
Oil leakage from the seal or the gasket could be the reason for rubbery odor when it comes in contact with the exhaust manifold.
Solution: We highly advise you to change the seal or gasket in this situation. For a temporary action, you could make the coupling surface of the seal or gasket firmer. But this way could also worsen the situation as the leakage would be worse when the gasket is saturated heavily with oil.
8. AC compressor heating
When the levels of refrigerant reduce, and there would be a lack of lubrication, which makes the AC compressor overheated and produces a smell of burning rubber.
Solution: You should get the AC checked by the mechanic during maintenance so that he could see whether it is charged to add more coolant or refrigerant accordingly.
Whenever you notice the burning rubber smells in your vehicle, it is important to take immediate action to avoid any serious problems. After that, get your car checked by a professional mechanic as soon as possible.
