SOURCE: Overheating
Many items need assessment. First what is THE COOLANT LEVEL enine running from cold start. IF LOW . Is there a coolant leak and where ? Lets say all of the previous check OK. ARE THE COOLING FANS OPERATING ? . They are , GREAT. Is it possible the cooling system ( i.e. radiator ) is clogged internally, or blocked exterior cooling fins of the radiator restricting cooling air. Hope this helps.

I am assuming you have the Northstar engine.
Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With
the engine idling,pull the purge line from the tank,if there is no
coolant flow from this small hose,it is blocked and this will cause
overheating.If the hose is clear, check for blockage at the nipple on the tank.
Are you running it without a thermostat? If so,then strangely enough,this will cause overheating as the Northstar cooling system is different to most conventional systems and therefore will not help you diagnose the problem.

Easiest way. Go to any auto store, Pep Boys etc, locate the book for the year of your car and write down the wire diagram.

you will need a new washer pump that is located in the washer reservoir and a new wiper motor cover which has the circuitry for the delay wipers. All you do is change them out with new parts and it will operate like new again

There is a block behind the washer bottle on the left under the hood and another block in the trunk on the left side.
