how do you bleed a diesel peugeot cooling system
The Northstar cooling system is self-purging. It's highly doubtful that you have an "air pocket" but if you must do something, take the cap off the surge tank and let the engine warm to around operating temp. If there are any bubbles they'll vent from the surge tank. Then replace the cap and you're good to go. But I'd be very suprised if you have an 'air bubble'. They just don't happen on the Northstar.
There is no reason to ever bleed a cooling system.
There is no need to manually bleed the coolant system on a Northstar, the system is self bleeding. The small hose on the side of the overflow tank is the self-bleed line. If, by chance, this line is obstructed, then the air will be trapped & cause overheating problems. Be careful is the plastic nipple on the side of the overflow tank as it is very weak & cracks easily.
Any time you flush out the cooling system you need to bleed the cooling system.
How do you bleed the cooling system of a 1988 acura legend? Is there a bleeding screw and where is it located?
If the cooling system is in good working order the system will bleed the air out itself. If the system has a leak anywhere no matter how small the system will never bleed the air out.
there should be a air valve on the engine that you can bleed the bubbles out of the cooling system.
NO!!!!!
Engine cooling system is not a closed system you can't remove the air.
