Coolant Line Help

[stello3]

working on 850 Spider Restoration

I removed coolant hoses from coolant lines running through tranny tunnel. There is a lot of build up in the lines. My question is can I just flush the lines or do I have to replace them?



should I need to replace the lines, that bend under the dash looks impossible to get in and out. Hmmmm

That's a typical look. Id just use the hose and open the heater valve and flush the heater core out. Take some sandpaper/steel wool to the outside of the metal lines and youll be good.

I'll give it a try, thanks.
