In 2016 Jeep models, the thermostat is located in the thermostat housing at the end of the engine’s cooling system, where the upper radiator hose connects. The exact spot varies by model and engine, but you’ll generally find it on the front or side of the engine bay near the radiator and water pump.
Engine types and thermostat housing locations
The following outlines the typical thermostat housing locations for common 2016 Jeep engines. If your model uses a different engine, consult the service manual for exact diagrams.
3.6L Pentastar V6 — Used in many 2016 Jeeps (Wrangler, Grand Cherokee, Cherokee). The thermostat is housed in the thermostat housing at the front of the engine, where the upper radiator hose attaches to the cylinder head. The housing is usually visible from the passenger side of the engine bay.
2.4L Tigershark I4 — Found in Renegade, Compass, Patriot and some Cherokee models. The thermostat is integrated into the thermostat housing that sits at the front of the engine, connected to the upper radiator hose and near the water pump.
2.0L turbo I4 — Used in certain Cherokee and other models. The thermostat sits in the thermostat housing at the front side of the engine, adjacent to the water pump and connected to the upper radiator hose.
Because the housing design can vary by trim and production changes, the best guardrail is to locate the big radiator hose and trace it to the housing; the thermostat is usually right behind or inside that housing.
How to spot the thermostat housing in your Jeep
The thermostat housing is typically a plastic or metal component where the upper radiator hose terminates on the engine. It may also house a temperature sensor or ping into the cooling system with bolts securing it to the engine block or cylinder head. If you follow the upper radiator hose from the radiator toward the engine, you’ll likely encounter the thermostat housing where the hose connects.
If you still can’t locate it, consult your owner's manual or a factory repair guide for your exact VIN and engine code. A mechanic can also identify the precise housing in your model year and trim.
Summary: For most 2016 Jeeps, the thermostat lives in the thermostat housing at the engine end of the upper radiator hose. The exact placement depends on the engine—3.6L Pentastar and 2.4L Tigershark cover the majority of models, with minor variations by model. When in doubt, check the service manual or seek professional help.
