bottom right hand corner of the rad. its a white pvs key like poking out..hard to see but look hard, and have fun taking it off
One flushes a radiator by draining the radiator, rincing the radiator, and then by adding a new coolant. One should remember that the drained coolant is toxic.
If by "bleed" you mean drain, disconnect the lower of the two hoses (do not confuse with the pipes from the AC evaporator) and drain the coolant into a bucket. If you are flushing the system (which you should if you are changing the coolant anyway), dont bother draining it, most of the coolant will flow out anyway, just do the coolant flush and fill from the radiator.
It flushes out old coolant and particulates which have formed in your cooling system.
Enough to shag it, spoken from experience ;) The average automotive radiator is actually two radiators in one - the larger section for the engine's coolant and the smaller section for the cooling of transmission fluid with some having a section for the cooling of power steering fluid. The only valve in a radiator is one at the bottom for draining and flushing of the engine coolant; the rest of the radiator's interior tubing is clear and un-restricted. landcranch
In the top of the radiator but be sure you've put all the pipes back on
You would remove it from underneath. There is a cross member which holds the bottom of the radiator and you remove this, after unhooking all the lines (trans coolant and engine coolant) and draining the radiator.
The coolant temp sensor on a 97 Buick Century is on the side of the radiator. It is just below the radiator cap.
The radiator on a 1995 Saturn is flushed by draining the coolant, refilling the engine with water, and adding a flush. It is allowed to circulate and drain before refilling with coolant.
You don't, unless you are flushing the system. Use distilled water and add it to the coolant recovery bottle - and it needs to be mixed with coolant.
coolant draining back into resivoir or possible air pocket
Mineral sludge from tap water. A good radiator flushing will help and then use proper coolant to help keep the sludge building up and blocking the radiator.
Because the motor is running to hot try flushing your radiator and putting new coolant in.
