Pardon my ignorance. I just got my G4 about 2 weeks ago. I wanted to check on the temperature but don't know how. Nag wawarm up kasi muna ako ng car before using it pero there's no way for me to check if it reaches the right temperature unlike with the old cars I used before. So I just rev for about 3-5 min. And how will I know when the time come na mag overheat (knocking on wood)? Thanks.
