Question about 1999 Subaru Legacy

1 Answer

The car smells like something under the hood is overheating. You can smell it around the wheels and the front of the car when you get out but it disappears very quickly as soon as the engine is turned off. No engine lights coming on and 2 mechanics have found no problems with hoses, clamps, etc. and the car runs fine. One guy thought it might be a very small oil leak onto the exhaust but I'm not showing any oil loss on the dip stick and nothing under the car. I did not notice this until I started using the heater this winter and it seems like the heater is hotter than it used to be - I never need it at the hgihest temp even in very cold weather. I don't know if this could be related. Thanks for any help!!

The most common cause of this is that the engines valve cover gaskets are leaking, they leak right onto the exhaust manifold, it only takes a tiny bit of oil to make allot of smell, this type of flat engine design (known as a "BOXER" design) is prone to this problem, have the valve covers checked for seeps, sometimes u can just tighten them down a little and stop the leak.THE COLD WEATHER MOST LIKELY HAS NOTHING AT ALL TO DO WITH THIS.

look under the hood while vehicle is running, this will be the easiest way to find it. it may be something as simple as a dry rotted rubber fuel line.

Burning plastic smell from under hood


You will need to check where the liquid is coming from, It may be anything from Air Con, Fuel, Transmission Fluid etc..

The fact you smell burning plastic could be 3 things..

1, Brake pads could smell and burn down if they are on too tight (Had this problem with a trailer). Hence when you apply the brakes it could be squirting brake fluid out due to too much pressure.
- Check brake fluid

2, If the smell and liquid is inside the car (front pass side) it could be the air ducts. Under the dashboard you have air ducts etc for the fans and in car cooling (brother had issue with this)

3, Whatever the fluid is, it could possibly drip onto something hot, unusual for liquid to smell like plastic though, Auto transmission oil smells like fish.

Best bet would be the brakes. Next time you smell it just smell in the wheel mag and see if you can smell it, check the engine fluids often and dont use A/C (Air Con) as that does drip fluid (normal). If it is the brakes smelling you will need to have the lines bled out, tyre places may be able to do this, and possibly new brake pads

Good luck

My heater works but is blowing a burnt rubber smell out of vents in a 1995 cadillac deville??? anybody kno? heater core??


Your blower motor could be overheating, but that usually smells like a distinct plastic burning. I's day its more likely a problem under your hood. I'd start with the belt and pulleys. Just pop the hood and look around your belt. If you see bits of rubber you found your problem. It will probably be a belt, pulley and/or tensioner that needs replacing.

Burning smell coming from my 2003 jeep liberty smells like a burning candle. Looked under the hood and the smell appears to come from a little electical box mounted on the passenger wheel side


I would take it to a shop right away. Do you see any fluids on the ground after you park or are you low on coolant or oil? This could be a electrical problem on its own. If you don't know what your doing don't go messing around with it.

Heard a grinding sound under hood. Car then died.


So does the a/c still work, maybe your compressor is bad? Top off your oil and run the engine and see if you can find out where the oil came from?

My 1993 chevy luminagets lousy gas mileage,when it runs you smell


. If you are in the car driving and smell fuel, chances are the leak in FRONT of you under the hood, probably being drawn in, by the heater or a/c. Open the hood and look for WETNESS. Don't see or smell it. Get UNDER the car ( safely ). Look around at the fuel lines. You'll find if you look. Hope this helps
