Can FTR coolant be flushed/ refilled and bled without using a vacuum filler?
Never used one before...manual is not clear from where you suck up the coolant; is it into the radiator end of the lower radiator hose after pinching off the reservoir hose?
Coolant can easily last 5-7 years (or even longer). It does not wear like oil or brake fluid does and replacing it every 2 years is a waste of time/money/coolant..
I have a vacuum bleeder. You would attach it to the neck of the radiator and pull a vacuum on the system from there with the other end in your coolant bottle, and the reservoir pinched off. Once done filling with the vacuum bleeder, put the cap on, unpinch the reservoir and top off. Its pretty simple.
