Daihatsu Hijet — Timing Belt

Interference engine — belt dimensions, Gates cross-references, and service notes.

Danger:The EF-series engine is an interference engine. If the timing belt breaks, the pistons will contact the open valves and destroy the engine. This is not optional maintenance — replace the belt at 60,000 km regardless of appearance.

Tensioner

The tensioner bearing should be replaced every time the timing belt is replaced. A failed tensioner will shred a new belt within miles. The factory also specifies a clearance check after installation: there must be 11 – 13 mm of clearance between the tensioner body and the oil pump housing before torquing the tensioner bolt.

Service Notes

While the timing cover is off, inspect the timing belt tensioner and idler pulley. Both are inexpensive and should be replaced alongside the belt — a tensioner bearing that seizes will shred a brand new belt within miles. Replacing them now costs far less than another teardown.

The water pump is also driven by the timing belt on the EF-series engine. If the truck has significant mileage or an unknown service history, replace the water pump at the same time. The labor to access it is already done.

Warning:After installation, rotate the engine by hand through at least two full crankshaft revolutions before starting it. Confirm all timing marks align correctly after rotation. Starting the engine with incorrect timing will bend valves immediately.

Timing Mark Reference

The crankshaft sprocket has a single timing mark that aligns with a cast reference mark on the lower engine front cover. The camshaft sprocket mark aligns with a notch on the camshaft bearing cap. Both marks must be aligned simultaneously before installing the new belt with no slack on the drive side.

Tip:Take a photo of the timing marks before disassembly. The marks are small and can be difficult to locate once the belt is off, especially if the engine bay is dirty.
