hi everyone,
i know this is an astra and zafira forum but i have a vx220 turbo (z20let) i couldnt think of anyone better to ask than u guys as the z20let is so popular. Anyway the water temp usually rises up to 85 degrees but recently its been dropping back down to 60 degrees (indicated by scangauge 2), put a new radiator in myself about 2 months ago and bled it with no problems even done a trackday since, temp stayed pretty stable, water temp sensor is only 4 months old so pretty sure its not that and im sure there is no air in the system or i wouldve noticed on the trackday, any ideas?
