I've looked into replacing the coolant temp. sensor and it looks pretty straightforward. But does anyone know if it can be done without having to drain coolant? That is the bit I might struggle with.

My temp. gauge reads ok, but I note it can still be a cause of a problem regardless.

I've plugged my code reader in which says no codes are logged, but its a cheap reader and I'm not sure I trust it to be right. I don't have an engine management light lit on the dash, but then I'm not sure if my car has one!
