Changing Coolant

stackman1

Hello Everyone. I have a 2002 OBS and was going to change my coolant. Done way too much reading and was about to buy the Peak Long Life concentrate as it seemed the best match. Then I read about also buying the Subaru Coolant Conditioner. Sounds like it is a good idea to stop some premature head gasket leakage which I can already see. Found it on Amazon. When I was there I also spotted what looked to be the OEM coolant itself from Subaru which incredibly on Amazon is more than 50% cheaper than buying the Peak at an Autozone. I have included links. Couple of questions: 1. Does my 2002 Impreza OBS have a bleeder valve to release the air in the coolant system or do I need to figure out how to burp the air via youtube? 2. I am so used to paying up for Subaru labels - any reason not to buy the Concentrate - paranoid? I have included the two links: amazon.com/gp/product/B007L72U1C/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A12WOLQM5J3T6R amazon.com/Subaru-SOA635071-Coolant-System-Conditioner/dp/B00IGZP2UE
