You can do a good job yourself, and a mechanic that has years of experience rather than a trade school certificate will do a fine job as well. It's not difficult work at all. Make sure the cooling system gets drained and refilled (use the Search feature above and look for coolant change), plugs and wires swapped, and probably an air filter and trans. fluid change (not a flush), along with a throttle body cleaning and lubricating all the hinges and joints. I think it's worth putting some silicone grease on the door, trunk, and hood seals after cleaning them with mild soapy water. They'll last longer that way and keep out the wind noise better. None of it is too complicated. Maintenance stuff is generally pretty simple. If you're talking about removing the engine for something, I would only trust an experienced mechanic with Northstar experience. For this maintenance cycle, though, anybody you trust will be able to do it just fine.jameslwalker said:My 1999 Deville base has 98,000 miles, in great shape. Should I take it to the dealer for tune-up, or can my good buddy ase certified mechanic do a good job.
I plan to keep this car until 140 or 150,000 miles.
Thanks for your opinion or experiences.
Maintain the cooling system meticulously. Use DexCool at 50/50 concentration with distilled water, and add the supplement in the hose rather than the surge tank. Replace the cap just to be on the safe side. It's very cheap maintenance. A 15 lb. cap is what you need. I think cooling system maintenance is the most important thing to do.jameslwalker said:Thanks for the info. Do you think there is anything I need to do to ensure the longevity of this vehicle?
Sounds like it may be a motor mount.Cadillac Davelle said:(oh last but not least any suggestion on a "clunk" i get when u have a heavy foot, i mean when i drive it slow and regular its fine but when im in a hurry on those days it makes that "clunk" noise, would this be the tranny mount or engine mounts gone bad?) so i dont want to end up going through a new radiator anytime soon or having to worry about over heating anytime also..
You said earlier that you plan to put another 40,000 to 50,000 miles on the car. The plugs will certainly have to be replaced before you sell the car so why not do it now and enjoy the performance of new and properly gapped plugs. Wires too.jameslwalker said:The car now has 104,000 miles. I haven't had the 100k maintenance done. The ses loght has not returned. On 700 mile trip NC to MD, I got 28.5 mpg, and on a 1800 mile trip NC to IN I got 27.4 mpg.
Can I continue to run it until I notice a drop in mpg or some other indication that plugs or wires are going bad?
