How to Check the Coolant for the 2002 Lexus LS430

The 2002 Lexus LS430 came with a 4.3 liter V-8 engine that produced 290 horsepower at 5,600 r.p.m. The fuel economy EPA highway mileage on the 2002 LS430 was 23 m.p.g. and 16 m.p.g. city mileage. The 4.3 liter engine is capable of creating 320 foot-pounds of torque. Checking the coolant on your 4.3 liter LS430 will keep the engine cooled to its proper level and maintain the life of the engine.

Instructions

1

Open the hood of your LS430. Stand in the front of the vehicle facing the radiator.

2

Place your hand on the radiator cap momentarily to see if it is hot to the touch. If the radiator cap is hot, do not open it or attempt to break the seal to depressurize the radiator.

3

Remove the radiator cap once you have verified that the engine is cool, or the car has sat without running for over one hour.

4

Visually inspect the fill hole at the top of the radiator. If you can see the metal fins inside the radiator, and you dont see any coolant, then you need to add some.
