An upcoming project...need a little advice

[85 DSEL]

Well I thinks me short coolant hose betwixt the t-stat housing and water pump is in need of replacement. Looking at the job nearly terrifies me! What is the prescribed approach?

I'm thinking that removal of the t-stat hosing is a must - then attach hose to the pump and replace the hosing? Sound feasable?

Also, I have read somewhere that a bit of sealant was recommended (at least by the author). Any thoughts?

And as always...THANKS to the best bunch o' guys on the MB forums.
