What can you check on Oldsmobile Silhouette 2001 will not blow hot air?
We replaced thermostat already .
Gaskets have been changed 2 years ago.
Help!
As long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference
There is not enough antifreeze in the radiatar. while the engine is cool and on level ground take off the radiatar cap and start the engine. let it run for 15 to 30 min. after the engine starts to get to operating temp. start adding antifreeze keeping the level at the top of the radiatar. it may over spill but what you are doing is getting all the air out of the system. this should take care of the heating problem. i forgot to mention. you want to keep your heating on high during this process.

The engine temperature is normal so I can I locate and flush the heater core.
Do you have a diagram or can you give me more details on how to proceed.
Thank you so much in advance!
