First, the engine rotates COUNTER Clockwise!!!
Second, the oil pump has a timing mark, also! Or, you really want it to all run thumping, and loud, with possible interference damaging parts?
Third, the entire full kit cost me <$135 online, with water pump, idler pully bearing, tensioner system, engine seals, sparkplug seals, valve cover gasket.
Furgal Mechanic, Rock Auto, Amazon, have good comparisons on prices.
The WATER COOLANT SENSOR, that screws on, is listed for HONDA costs $11.06 to $76.31 each (TX37x/SU4006/5S1468), but, THE SAME screw thread brass housing SENSOR using an O ring seal, is used universally, on FORD Explorer, 1998 through 2001 vehicles, built to 12/11/00 (REPM318301) is sold online for $3.06!!!
CAUTION, later sensors on FORDS are clip on, not screw thread!
