Having problems with your Buick Skylark ?

Running hot The car was running hot and we noticed that it wasn't bleeding air out of the system properly. The Bleeder hose was completely clogged with brownish solidified sludge so we cleaned it out 100%. It seemed to work for a week or so and now it is hot again. Should I flush the system out, replace the radiator etc to catch all the sludge or is this some other larger issue? Also, fyi, replaced the water pump due to a leak. Holding pressure just fine now.

Answers :

Depending on the age of the car and the maintenance done, or not, the cooling system could be clogged up. That would include the block and the radiator.
You can try having it power flushed where a machine is connected and coolant pushed thru and filtered.
Often times the sludge is caused when the coolant level is low and air pockets form.
