Precision Works ユニバーサルインラインターモスタットハウジング - 1.25インチホース

Had to flush my coolant anyway after a thermostat stuck closed, so this 1.25" inline housing made the swap straightforward. The universal fitment meant I didn't have to hunt for a model-specific part, and the hose fittings grabbed tight with no leaks on the first run.

Swapped this onto my swapped Civic to finally control the temp on my custom radiator setup, and the 1.25" hose barbs sealed up with just basic clamps, no leaks after 300 miles. The housing itself feels solid and the thermostat drops right in without any trimming.

The 1.25" fittings slid right onto my radiator hose without any leaks after tightening the clamps. It feels solidly built, and the universal design meant zero modification for my setup. My engine finally runs at proper temp.
