Toyota's website and the Toyota Owners Group site (where you'll find a complete maintenance schedule posted) says the first coolant replacement is at 100,000 miles or 120 months whichever comes first. Thereafter coolant changes are scheduled at 50,000 miles or 60 months whichever comes first. This is an arguable statement but I'd suggest sticking with Toyota's own brand of coolant rather than picking up whatever's on sale at a department store. If you're due for a change and will be doing it yourself you should flush the system thoroughly before adding the new coolant. You can use a commercial product or the old shade tree version, a 50/50 mix of distilled water and white vinegar. If you use the latter pour it in then run the engine for a half hour or so. Allow to cool then drain. Refill the system with distilled water, run the engine again then drain. Now you have a nice clean system and can add fresh coolant. If you use one of the commercial flushes follow the instructions on the container. Cheers
5,000 miles
Every 90K miles.
Timing chain usually needs to be replaced each 180-200K miles.
Your reservoir may be low. This will trigger the coolant light. It is often a malfunctioning sensor and nothing is actually wrong with the cooling system or coolant. It can be easily replaced. Alternatively you can leave it, but monitor your engine temperature and coolant level.
When the computer throws the code that you need to change the sensor.
It should last the life of the engine and is normally replaced during an engine overhaul.
AnswerThe coolant should be totally drained and replaced every 2 years. Use premixed coolant so you don't have to dilute with any water. If you do use concentrated antifreeze, dilute only with DISTILLED water. Make sure you buy either genuine Honda coolant, or silicate-free coolant that is designed for aluminum engines.
It is often useful as a coolant because it can absorb thermal energy without a large change in temperature.
Tires require changing after a number of kilometres covered and will be specified by the tire manufacturer. Findout from your tire dealer.
Change it every 100,000 miles on the 4 cylinder and change it at 105,000 miles on the V6 at the same time you have the cam belt and water pump replaced.
Timing chains will normally last the life of the engine and are replaced during a complete engine rebuild. Therefore, no maintenance is required.
Ideally, you should change it regularly. Your Auto Zone store can provide the answer as to how often. Different autos, trucks, etc., are different because of usage.
