I think I should change the coolant every year. I don´t know if I shuold use toyota coolant, or if I could use prestone coolant.
Is it necessary or mandatory to clean the injectors every year?
Or just occasionally use the additives, which are put into the gas tank.

Greetings.

Youre welcome.
Yes 20w 50 is perfect, 20w 40 though should be the thinnest you should go. The number with the W is mostly for winter only, which im no expert at, but the manual should say you can go as low as 0w 40.

Coolant? We ver used them, After replacing the original coolant that came with all our cars, i only ever used distilled water. Not surr how hot it gets there in Costa Rica, but we get max of 40degC only, and distilled water work fine. Replacing coolants should be around 5years or x number of kms, not every year.

You dont ever need to clean injectors unless they are acting up or you feel like cleaning them, which isnt necessarily every year. 5 years maybe? Additives you dont need them as much. Just use good quality gasoline like chevron (caltex brand here in Asia) which have injector cleaners.
