190 thermstat to block hose

[kanadary]

first of all thanks for all the great messages about changing the t-stat and coolant. i didn't know that the valvoline product was the same as the MB one. question, i have a 87 190E-2.6 and would like to replace that small hose between the block and the bottom of the t-stat housing. what is involved in this? do i need to unscrew the housing to the block to get at it. its just preventative maintenance for me since the hose has never been changed out. thanks Ken
