325i. Thermostat was done at a garage, so presumably was bled correctly.

Thermostats has been replaced

Heats up fine but loses warmth when you get up o to speed, so above 50ish. Any suggestions?

Hi

Had my ‘88 325i Convertible since 2018. Was in reasonable condition so have been doing a few bits and bobs to it over the last couple of years. Mechanically its great, so this years project is to sort out the upholstery - there’s a few rips on the seams to sort out.
