The most likely culprit is a blown gasket or cracked head on one of the cylinders, where fuel lines and coolant lines intersect. This can pull fuel or exhaust gas into the cooling system.
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.
No who, but what. All internal combustion engines emit exhaust fumes.
Intake Manifold....smelling radiator fluid fumes in cabin or white smoke in exhaust. Exhaust manifold or cylinder head....smelling burnt oil in cabin or black smoke in exhaust
Exhaust
The exhaust system is what muffles the engine sound keeps the fumes out of vehicle and away from the vehicles occupants and also filters the exhaust fumes out.
your exhaust may be jammed
Exhaust fumes from cars are an example of air pollution. They contain harmful gases and particulate matter that are released into the atmosphere, contributing to environmental and health issues.
You kids exhaust me! That exhaust fumes from that car are choking me.
Exhaust
They don't. You need to stop sniffing exhaust fumes, mister.
There may be a hole in your exhaust system causing fumes to leak into the car. This can be dangerous and should be fixed immediately.?æ
Leak in exhaust system perhaps exhaust manifold being sucked in through air intake (grid at lower end of windshield)
