Tech Tip: No Start in Cold Weather Due to No Weep Hole

Tech Tip: No Start in Cold Weather Due to No Weep Hole

This condition can be caused by condensation freezing in the muffler assembly.

MODELS

  • 2015-2020 Jeep Renegade
  • 2016-2020 FIAT 500X
  • 2017-2018 Jeep Compass

CONDITION

The customer may describe a crank, no start condition, in freezing temperatures. This condition can be caused by condensation freezing in the muffler assembly.

CORRECTION

  1. Raise the vehicle on hoist. 
  2. Is there a weep hole on the end of the muffler as shown at the location in Figure 1?
    YES: This bulletin does not apply. Normal diagnostic efforts should be performed.
    NO: Proceed to Step 3. 
  3. The weep hole must be drilled into the end of the muffler assembly as shown in Figure 1.
  4. Using a 3 mm (1/8 in) drill bit and a drill, drill a weep hole no deeper than 2.5 cm (1 in.) into the muffler assembly at the bottom lower corner.

Poor Engine Performance Linked To Converter Failure

Today’s modern vehicles are equipped with a sophisticated emissions control device. These fail when the engine is not tuned up, as this leads to overworking the converter, overheating and possible clogging.

Today’s modern vehicles are equipped with a sophisticated emissions control device. These fail when the engine is not tuned up, as this leads to overworking the converter, overheating and possible clogging. Poor engine performance is the #1 reason converters fail. The catalyst is exposed to raw fuel and high exhaust temperatures which can shorten the life of the converter.

Diesel Exhaust Particulate Filters: How Do They Work, What Do They Do?

The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tailpipe. The honeycombed inner structure is covered with a layer of a chemical catalyst that contains small amounts of precious metals, usually platinum or palladium.

Oxygen Sensor And Catalyst Efficiency

The catalyst efficiency monitor verifies the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter. These “tests” are called the readiness monitors.
