How do you change a heater core in a 2005 Buick rendezvous

If it has an automatic transmission it isnt the best thing to do.The transmission pump wont suply lube to parts that need it and stand a real good chace of causeing damage due to the lack of lubrication.

Hi there,

Well the heater core is located under the dash on the passenger side, usually cased in a plastic housing.You may have to remove the glove box in order to have access to. And when you get to the point, when you are disconnecting the coolant lines and remove the core you use some clothes to protect the carpet as fluid may drip. Post comments for further help or information........
Good Luck!!

Thanks for using FixYa!!

here is a pic of the thermostat housing in case you dont know what it looks like. its a very easy part to change although sometimes they are hard to get to. just make sure you do not put the thermostat in backwards the coil on the thermostat should go towards the hot side (coolant coming from the engine)

Most probably some ignition cable to the spark plugs.
