Where do you put an aftermarket temp gauge in a 4.0 HO Cherokee?

To install an aftermarket temperature gauge in a 4.0 HO Cherokee, you'll typically place the temperature sender in the engine's coolant passage. The most common location is in the cylinder head or intake manifold, where you can tap into an existing coolant port or drill and install a fitting. Alternatively, you can replace the factory temperature sensor with the aftermarket sender if it matches in size. Ensure the sender is securely fastened and wired correctly to the gauge for accurate readings.
