Loosen the timing belt tensioner bolt, push the tensioner back, and temporarily tighten it to compress the spring. Remove the old belt.
Precise torque sequences prevent component warping and fluid leaks. Always use a calibrated torque wrench. Cylinder Head Bolt Torque Sequence
Loosen the tensioner bolt to allow the spring to apply tension to the belt.
A common issue with high-mileage 5A-FE engines is internal oil leaks. The manual dictates:
Engine stutters or hesitates under load; flashing Check Engine Light.

For over two decades, the has been the silent workhorse of the automotive world. Found under the hood of legendary JDM and export models such as the Toyota Corolla (EE90/EE100), Tercel, Paseo, and the first-generation Toyota Echo, this 1.5-liter, inline-4 cylinder powerplant is beloved for its fuel efficiency, longevity, and silky-smooth operation.
The 5A-FE manual covers only the 5A-FE. It knows that your engine uses a distributor (most variants) while the later 7A-FE uses coil packs. It knows the exact shim clearance for the bucket tappets. You cannot fake that level of specificity.
The Toyota 5A-FE is one of the most reliable inline-four engines ever built. Introduced in the late 1980s, this 1.5-liter powerplant features a Dual Overhead Cam (DOHC) design and electronic fuel injection (EFI). It powered millions of vehicles globally, including the Toyota Corolla, Carina, Corona, and Sprinter.
Check if the upper and lower radiator hoses are both hot. If the lower hose remains cold, the thermostat is stuck closed.
