How do I Troubleshoot a 1988 Toyota Pickup?
Toyota has manufactured a long line of pickup trucks since 1964. Like other modern cars that are still being driven today, the trucks developed in 1988 were equipped with many different parts and systems. These parts and systems can make it difficult to properly troubleshoot a problem you are experiencing with your car. One method to troubleshoot your Toyota truck is to determine what type of smell the car is emitting and what portion of the car the smell is coming from.

Inspect the battery when a sulfur-like smell comes from your engine as you drive. The battery may be leaking electrolytes. If the sulfur smell is emitted while the engine is idling check the engine exhaust and fuel system components for damage and wear. These components include the oxygen sensor, catalytic converter, MAP sensor, coolant temperature sensor, fuel injector pressure regulator, carburetor and PCV valve.

Look at the clutch bearing on the transmission when your car has a burning metal smell as you drive. The bearing will wear out and become dry and seized from time to time. If the smell comes from either the front or rear wheel area instead of under the car on the transmission, the wheel bearings and wheel hub bearings may be incorrectly tightened or installed. When the burning metal smell is strongest after you turn your car off the front wheel spindles may be worn or damaged and need to be replaced.

Examine the heater core of your Toyota when you can smell a sweet smell similar to antifreeze. The heater core may be leaking antifreeze into the floor area of the passenger compartment. If you can only smell the antifreeze when the heater is on the heater control valve may be leaking or faulty. When the smell comes from the engine more than the passenger compartment, inspect the radiator motor fan to see if it has become inoperative and the freeze plug to see if it is leaking.
