Thread: General Maintenance on a 08 Grand Prix at 50, 000 miles

Tranny fluid n filter... Fuel filter if accessible but I believe it's in with fuel pump on this yr... I'd also recommend suspension bushing check n replace (sway bar links and control arms)... Also do visual check on plugs n wires (they are rated for 100k but I'd check anyways to find probs)... I'd also test radiator fluid to make sure temp rating is stable

The coolant needs replacing, its five or more years old. It's rated for five by GM.

Every fluid in the car is likely past it's prime. This includes brake, power steering, coolant, transmission.

Ok Thanks for the info!

Thanks!

As far as the plugs and wires go. Is it best to go back with the original plugs by the manufacturer or would you recommend another brand?

You can save a bit on wires and get a premium lifetime warranty set.

On the plugs, AC Delco 41-101. Easiest way to go as that is the factory plug which will be good for another 80K.
