I had the same problem on my SL1 2002 and my wifes SL2 2001. In both cases, the electric radiator fan motor needed replacing. It was not difficult but took me a full day of trying to figure out how to pull the plastic housing it is mounted in. Someone who knows what they are doing could have changed it in a half hour. Works great now.

you can try this, on the exhaust manifold there is a heat sensor you can replace this or take off the connection and with a small piece of electrical cable strip both ends put into the connection and that will put the fan on , if this fails then the fan itself is at fault [driver87]

The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,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.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.
Also note that the cooling fans don't come on until the coolant temperature hits around 225 degrees.
During normal highway driving the fans will very rarely come on(if at all) due to constant air flow through the radiator.They will only usually come on in heavy traffic conditions on a hot day.
But......if you have the Air Con switched on, the fans will run all of the time.

Hello and welcome to FixYa!
If you have overheating problem, it can lead to multiple
issues. You may be running on low coolant that's why the vehicle overheats. If
that's the case, please add coolant and make sure that it sits on the right
level, too much coolant can cause overheating too for coolant will overflow.
The vehicle may have a faulty or worn out radiator blower
motor that's why it overheats. If that's the case then you will need a blower
motor replacement to resolve the issue.
If the radiator is clogged with dirt and rusts this issue
occurs too. The coolant doesn't flow normally on the cooling system if it's
clogged. If that's the case, I strongly suggest that you have the radiator
flushed to drain out dirt and rusts. If you think that the radiator served you
enough then it's better to have it replaced.
Please do check the radiator hoses, If you have worn out
hoses it can cause coolant leakage which can result to overheating. A tiny hole
is good enough for the vehicle to overheat.
A faulty thermostat sensor can cause the issue too. If you
have worn out thermostat, the fan may not trigger that's why the fan won't work
when under stressed conditions. A blown radiator blower fuse can cause this
issue too so I suggest that you check the radiator blower fuse and replace it
when necessary. What causes the radiator blower fan fuse to blow? It's because
of a failing radiator blower motor, If that's the case have the radiator blower
fan motor replaced.
If the fluid in radiator doesn't circulate then it means
that you have a blown head gasket or a faulty water pump. I suggest that you go
for the water pump replacement first specially if you think that it's near the
end of it's service life. Usually, water pops out the radiator when engine is
reved (a sign of faulty water pump and possible blown head gasket).
Hope you find this information helpful enough and thank you for using FixYa! Have a good one!
