STEP 1. Check for coolant leaks.
| warning | When pressure testing the cooling system, slowly release cooling system pressure to avoid getting burned by hot coolant. |
| caution | - Be sure to completely clean away any moisture from the places checked.
- When the tester is removed, be careful not to spill any coolant.
- When installing and removing the tester and when testing, be careful not to deform the filler neck of the radiator.
|
Check that the coolant level is up to the filler neck. Install a radiator tester and apply 160 kPa (23.2 psi) pressure, and then check for leakage from the radiator hose or connections.
Is leakage present from the radiator hose or connections?
