Are you sure its the rad? BMW suffered from viscous fan failure. Symptoms were overheating in stationary traffic but ok when driving along.
Remove the Radiator and have it serviced if they are able to. If not you will need to replace it, would be a good time to replace the Radiator hose's as well. Hope This Helps.
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
I would suspect the thermostat is the culprit. Replace the thermostat. definately replace the thermostat, get a new gasket and all. Also, start the car cold and see if the inlet hose to the radiator warms up evenly. if it gets really hot on the engine side of the hose and is still cool by the radiator that means that there is no flow and either the thermo is installed wrong or something is clogged
There are several possible causes. 1. Check the fan. When the car is overheating, if the fan is spinning slow that means the clutch is defective. 2. When overheating, touch the upper and lower radiator hose. If upper is cool, replace the thermostat. 3. when overheating, upper hose is hot but lower isn't. That means the radiator is clogged. 4. upper and lower hose are both cool, water pump is defective.
possible radiator resrtiction
Check the thermostat and replace if you have more than 30,000 miles on it They sometimes stick partially closed and cause overheating. A second cause may be a clogged or undersized radiator. You can have a radiator shop clean it or better yet, have them build a new radiator but add an extra row of coils to add extra cooling.
Check the fan clutch, it may not be working properly.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.

Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
my 1993 Toyota Camry radiator had a hole in it it was overheating. I replaced the radiator. The car is still overheating where is the thermostat located. First, drain your coolant from the radiator. Find your lower radiator hose and follow it to the metal housing. This is the thermostat housing. Remove the 2 nuts with a 10mm wrench. Remove the thermostat and replace with new one and new gasket. Re-install and re-fill your radiator with new coolant. Drive the car with heater running. Allow the engine to cool and top off the radiator. Add coolant to the reservoir to halfway between Full and Low.
change th radiator it must be blocked feel th radiator shoud be evenly hot.

Could be from a variety of things. Commonly overheating occurs when the car is low on coolant, broke thermostat or the radiator needs repairs.
There are several causes that will reduce the water level in your car radiator. The most common cause is evaporation. Engine overheating will also reduce the radiator water level.
Either the cap is defective or too much pressure is building up in the system. I would replace the cap is it does not appear to be overheating. answer you have a defective radiator cap replace with a new one with same pressure rating as old one
If the engine is not overheating and the temp gauge reads normal, the thermostat is doing its job. If the engine is overheating, the thermostat may be stuck and in need of replacement.
IF IT WAS NOT OVERHEATING BEFORE THE HOSE WAS REPLACED -- MORE THAN LIKELY YOU HAVE AIR POCKETS TRAPPED IN YOUR COOLING SYSTEM
Overheating an engine can seriously damage the heads. Check for water in the oil. It may look milky.
Replace the radiator with a new or good used one.
The radiator may be plugged. Take it to a radiator shop.
