Why would a 91 cutlass cierra smell like maple syrup when the heat or defrost is on?
your heater core is leaking anti-freeeze.
Mrs. Buttersworth is paying you back for years of pouring too much syrup on your pancakes!
it means you have a collant leak (anti-freeze) of some kind start with water pump.
sounds like you use a bad mechanic a good mechanic would replace a cracked exhaust manifold to start with if you can smell gas,there is obvioulsy a leak in the fuel system. this needs to be found as it is a fire hazard
How do you change a thermostat on a 1997 Pontiac Grand Am?
Should be located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from radiator
Remove housing
Make note how thermostat is installed
Clean both surfaces
Replace thermostat and gasket
Re-fill coolant slowly to prevent an air lock
Start engine and look for leaks
Run engine to normal operating temperature with heater on
Re-check coolant level
if its a rotten egg smell its probably the cat if its loud volume look for a blown gasket or a hole in the pipes

Purchase a Purolator Cabin Filter. It comes with complete directions.
Do fuel filters leak when clogged?
no they don't leak unless you have a bad connection at the line. If you have any doubts about it being clogged just change it. they only cost a few dollars and almost always make your car run a little better!
How come you can smell fuel coming in heating vents in a 1996 Chevy cavalier?
There is probably a fuel leak somewhere. You should have a professional check it out ASAP. There is a possibility of a fire if left alone.

Anything softball sized or bigger is excellent.
How long does it take to replace a head gasket?
if a small gasket crack is suspected then it may be possible to fix by using
a bottle of Bar's Head Gasket Repair. It is a permanent repair and only costs
around $10-$12. Much easier than breaking down to the head gasket.
What do you do when you smell fumes?
If you smell fumes, you should get out of the room, car, or house. Opening windows will help get rid of the smell.
How do you test for exhaust fumes in the coolant?
You need a special tester called a block check. You fill it with a special fluid and then
use it to suck fumes out of the radiator . if the fluid turns yellow it means there is exhaust gasses in the coolant.
What is it if you smell a burning smell coming from the exhaust?
You may be burning oil.
EDIT: This is a very vague question. Did you recently get exhaust work done? if not, you should first check to see if there are any lights on the dashboard that have recently come on. If not, check your spark plugs for wear. Any unburned fuel exiting the engine will pool in your catalytic converter and cause a chemical reaction to the platinum catalyst, which in turn will cause it to become VERY HOT. (when I say very hot, i mean White HOT.)
so, to follow up. Exhaust work will leave a burning smell from gasket sealer as it heats up for a couple of weeks following. If there are lights on the dashboard, it means that one of the O2 sensors has malfunctioned and you are not getting a correct mixture of oxygen and fuel in the engine for combustion. If there are no lights on and your spark plugs are worn and burned, it means that escaping unburned fuel on the exhaust stroke of the engine is causing the catalytic converter to become overheated. Other than that. I will need more information. Hope this helps.
A leak could potential cause the issue you describe and still keep the engine from overheating. I would suggest having the cooling system pressure tested for leaks and having any leaks repaired.

Check your Serpentine Belt and pulleys. The Serpentine Belt maybe in need of replacement.
