Toyota Tacoma (2015-2018) Service Manual: On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT FOR COOLANT LEAK
HINT:
- The sliding surface inside the engine water pump assembly is lubricated by engine coolant. As some engine coolant is discharged during normal operation, engine coolant residue (solids) may be found on the drain plug or the bottom of the engine water pump assembly. Also, engine coolant may leak if foreign matter enters the engine water pump assembly, however the sealing performance will recover when the foreign matter is pushed out or breaks into fine pieces. In this case, check the area around the engine water pump assembly.
- Before performing this inspection, check that there are no engine coolant leaks from any parts other than the engine water pump assembly. If there are leaks, inspect those areas first.
- Perform this inspection when the engine is cold.
(a) Visually check the engine water pump assembly.
(1) Check that engine coolant is not dripping from the engine water pump assembly.
HINT:
- If engine coolant is dripping, replace the engine water pump assembly.
- If engine coolant is not dripping, perform the following check.
(b) Inspect the area around the engine water pump assembly.
HINT:
Check for deposits around the drain plug of the engine water pump assembly.
(1) Remove the fan pulley (See page .gif)
).

3. INSPECT FLUID COUPLING ASSEMBLY
(a) Remove the fan with fluid coupling assembly (See page
).
|
(b) Remove the 4 nuts and fan from the fluid coupling assembly. |
|
|
(c) Check that the fluid coupling assembly is not damaged and that no silicon oil leaks. If necessary, replace the fluid coupling assembly. |
