Mass airflow sensor(MAF), is located in the airway between the throttle body and the air filter of an engine.
i suggest you to clean the sensor from all dirt to make the sensor accurate air flow readings.

LOCATIONS
There are different locations in the exhaust system where O2S sensors are positioned. The locations have been given numbers and will be used in the accompanying charts to identify the positions of O2S sensors in most vehicles.
Due to mid-year production changes or factory inconsistencies, all models may not be covered. If a vehicle being serviced is not covered in the charts, inspect the exhaust system (while cold!) in the general locations to find the applicable O2S sensors.
NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2S sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service.

Fig. 2: Location No. 1 — typical O2S sensor located in the exhaust manifold
Fig. 3: Location No. 2 — left and right banks of a V-type engine
Fig. 4: Location No. 3 — exhaust collector (where more than one pipe joins together)
Fig. 5: Location No. 4 — outlet of the catalytic converter
Fig. 6: Location No. 5 — inlet and outlet of the catalytic converter

The coolant level sensor is inside the coolant bottle. It is not replaceable separately. You will have to replace the reservoir to replace the sensor.
