if you replace your intake gaskets (upper and lower) use the latest updated lower gasket that is aluminum, my mother in law had this done then gave us the car, within 3 years it had failed again, the repair shop had used the old style plastic lower gasket, so this time i did it and flushed all the dex cool (bad stuff)out of the engine and replaced with peak antifreeze,also replace the two plastic coolant elbows but get them from the dealer do not use the doorman ones from auto stores as the rubber o ring is slighty smaller and WILL fail within 4 months.
