Fixing P0128 on My 2017 Jeep Wrangler — EASY Thermostat Replacement!
What happens here
The presenter shows a side-by-side comparison of the old and new thermostats. The new thermostat, branded Mahle, is identified as an identical original equipment manufacturer (OEM) part to Mopar, despite its different branding and significantly lower cost. It is crucial to use the correct type of coolant, which for 2013-2017 Jeep models is Organic Acid Technology (OAT) coolant. The presenter explains that mixing different types of coolants (like OAT and HOAT) can lead to the formation of a sludgy, solidified mess in the cooling system.
Goal: Verify the correct replacement part and understand the importance of using the appropriate coolant type.
