millhouse Posted January 18, 2016 Share Posted January 18, 2016 Any tips on how to flush the rad on my fiesta mk6 tdci going to give it some fresh coolant going to flush the system 1st Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 18, 2016 Share Posted January 18, 2016 I usually just pull the bottom hose off the radiator to drain the system. To flush the radiator just remove the other hose and use a garden hose to flush water through in both directions. Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted January 19, 2016 Share Posted January 19, 2016 You don't need to remove a hose... (Although you can if you want to) Look underneath the nearside of the car, under the radiator. You'll see a plastic Philips head bleed screw. Undo it and drain the coolant out. Make sure the expansion tank lid is off. Then tighten the screw up again. Insert new coolant, then undo screw enough to let air out. Tighten screw Start engine. With heater set to hot & leave to idle for a few minutes. Keep an eye on the coolant level and top up as necesarry. Once the car is slightly warm raise the revs to 2k for 5 minutes, keeping an eye on the coolant level Be sure to tighten the bleed screw as tight as possible or the o ring won't seal! 1 Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 19, 2016 Share Posted January 19, 2016 Always opted to drop a hose, if you damage or snap that plastic screw your in trouble. Undo what screw to let air out? Not the one on the bottom of the radiator I hope lol. 1 Quote Link to comment Share on other sites More sharing options...

Yes.. the one in the bottom of the radiator.. that sat letting air out for 30 seconds before any coolant came out After I did my timing belt & water pump etc www.yorkshiredetailing.co.uk - approved resellers of the Highest quality detailing & Valeting supplies Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 19, 2016 Share Posted January 19, 2016 I can't see how, the air would rise not fall. With the cap off the system will burp itself 1 Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted January 19, 2016 Share Posted January 19, 2016 Well that's what happened, its how I bled the system twice with no issues www.yorkshiredetailing.co.uk - approved resellers of the Highest quality detailing & Valeting supplies Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 19, 2016 Share Posted January 19, 2016 You won't be bleeding air from the lowest point in a cooling system. They air will have come out from the cap being removed. 1 Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted January 19, 2016 Share Posted January 19, 2016 The Cap was removed anyway to put coolant in. The screw was tightened up. It barely took any coolant despite it being empty. As soon as I opened the screw you could hear the air escaping at first. Then the coolant began to come through I'm not saying you're wrong, I'm just saying what I've experienced www.yorkshiredetailing.co.uk - approved resellers of the Highest quality detailing & Valeting supplies Quote Link to comment Share on other sites More sharing options...
St180ginger Posted June 13, 2019 Share Posted June 13, 2019 How much antifreeze do I need for my st180 Quote Link to comment Share on other sites More sharing options...
iantt Posted June 13, 2019 Share Posted June 13, 2019 St180 fiesta holds 6.2 litres coolant mix from dry, but you won't get all coolant out. So a 50/50 mix of antifreeze and water you will need approx 2.5 to 3 litres antifreeze . 1 Quote Link to comment Share on other sites More sharing options...
