hi i own a 2003 volkswagen golf gl and im wondering what coolant best fits the model. the engine symbol keeps lighting up on my dash. i've checked my motor oil and it looks alright, im beginning to wonder if the radiator needs to be refilled. today i was trying to find the opening to the radiator but cannot find it, i need help. i dont know where the opening so i can fill coolant in. ty

 

should be just a reservoir to fill through and as far as coolant as long as it's a coolant that states "mixes with any vehicle or color coolant" you're fine. Ever need a small question like that contact your local autozone.
