I signed up a few years ago but have not been active. Now retired (with a little more time) I'm paying attention to our 53 plate Celica - 200k+ miles and still going strong! Happy to share experiences and look forward to your support.
I've got a newish (2003) Celica 1.8VVTI. The coolant level is low. I know you're supposed to use the proper Toyota pink stuff, but how do you get at the filler cap? It's underneath a plastic cover.
