Since the t-stat is under the hyd. pump ( at least on my 91 200 ) I
would just pull the pump and do the deed. When pulling the pump just
keep it as level as possible to not loose the prime. If nessacary when
reinstalling, prime the pump before attaching the belts and hyd lines. I
pulled the pump when doing my radiator and found it made thing really easy.
