Review on 💨 Enhanced Cooling Thermostat Housing Assembly - APDTY 013315 by Ron Turner

I ordered this build for my 2001 Sport Trac. I came fully assembled with a new thermostat and both sensors. This case is a known problem with the 4.0 engine as the bottom of the case will only crack and leak when your engine is running above 2000 RPM or so. Finding this leak drove me nuts for months until it got so bad that coolant was flooding the top of the block. As soon as I removed the bottom knot I saw a tear that was over 2 inches long. I would highly recommend this replacement unit and would purchase again should the need arise.
