Yes it is, but don't be afraid to check the coolant level, Just top off the radiator and bring the expansion tank up to the full mark. It will balance itself off. Hope this helps.

How do I remove radiator to a 2000 buick century custom

Most radiators have a fan bolted to the front which needs to be unbolted and removed. Drain the radiator with the drain plug in the bottom, then remove the upper and lower hoses. Next remove the bolts holding the radiator to the frame ( there will probably be about six: two at the top, two half way down, and two on the bottom. Sometimes there are only the two on the top and the radiator sits into little cups. In which case, after removing the bolts juts pull up and out.

drain raditor fluid then take off upper and lower hoses and put your house water hose in lower raditor hose and turn on water and let run for about 5 mins. to flush out raditor.
then run in top hose to flush back then lower hose again. that should clean it out.

2000 Buick century custom only has heat when you accelerate fast but puts out cold air when you accelerate normally or at a steady speed.

Check your coolant level. Not enough fluid in the radiator to circulate when the engine is operating normally.

2000 chevy silverado normal operating temp 210 , recently temp rises to 250. water pumps no leaks therm. appears OK .

With the truck running at operating temperature, squeeze your upper radiator hose. You may have to check it a couple times allowing time for your thermostat to open. Are you able to compress the hose a little when you squeeze it or does it remain stiff/solid? Your thermostat may be stuck open or even stuck closed.

Buick is overheating

Follow the radiator hoses from the radiator to the block. Check the upper radiator hose first. At the end of one of these hoses will be a housing to which the hose is connected. The housing is bolted to the block. The thermostat is in that housing.

Remove termostat housing bolts. Note orientation of old thermostat. Clean gasket material off housing and block. Put on new gasket, install thermostat. Replace housing, etc.

You may have to disconnect/remove other parts to get to the housing botls, maybe not.
