2015 Chev Equinox Rad cap

No, the reservoir is pressurized so there's no cap on the radiator itself. Make sure you get all the air out of the cooling system. Hope that helps! Jim

It does help very much! Thanks a lot! How do you get the air out?

You're welcome. Glad to help! If there's no bleeder screw you should, with the engine cold, remove the cap from the reservoir and start the engine. Add coolant to the full line and keep an eye on the coolant level as the engine warms up. As the coolant level drops down, keep adding to the full line until the engine is fully warmed up and the coolant no longer drops down. This may take up to 30 minutes so be patient. Then you should be all set. Hope that helps! Jim
