I'd go with the Bonneville, it's a little sportier and might handle better with a little more power. I think the underpinnings are same as the Grand Am.
Another viewpoint...OTOH, the Town Car is built on the same chassis as the Mercury Grand Marquis and Ford Crown Vic ... and the Crown Vic has been used for countless police cars, the Town Car used to be the standard for Taxi's and base for many limo conversions. So what do you want? Sporty w/handling, or Luxury? I know the Town Cars were well known to routinely hit 200,000 or 300,000 miles in limo/taxi service. My '95, now 16 years old, is still going strong...if you take into account I had the trans rebuilt around 110,000 miles, and swapped the airbag rear suspension for standard coil springs when the air bag developed a leak. As far as I know those are the two most common repairs as they age...I have no experience with the durability of the Bonneville...
Pontiac oil pressure can be tricky! Check with your mechanic first but from my experience with my Pontiac use 10w-40 oil in the winter and 20w-50 in the summer. That has produced better pressure in mine.
Any DEXRON-III synthetic transmission fluid. Some brands seem to work better than others.
with the hood open stand in front of the engine look toward the backleft it is usually under the intake manifold use a flash light you will see it better
According to the 2008 Bonneville manual it uses 89 octane or better unleaded gasoline.
== == The car is about 16 years old, it needs a complete rad and heater core flush, to get the junk out of it, and make the system operate better, and more effectively. A professional radiator shop can do that for you.
currently at 239,000+ and going strong! It rides and handles far better than our 2001 Ford Taurus with less than half the number of miles ... but then, considering the Ford Taurus that is not saying very much!
Yes because the impala has a better engine with more horsepower and torque ratio. But if the Bonneville is an sses and its supercharged then i don't know,
no one is better then lincoln ormsby
To the left and below your alternator- you'll have to reach down to get at it!its near passenger side firewall- there is a cap- top of cap has inscription- Power Steering Fluid Etc. You might want to use a flashlight for a better view.
Take the car to the dealer and have them check the map sensor.They usually charge about 33 dollare to check this ,its better than replacing things one by one and enc up spending 200 dollars for a 75 dollar repair
He is probably in a better place. R.I.P. Abraham Lincoln.
If it's a newer Bonneville (1999-200?), then it's 5w30. Anything older than that usually takes 10w30. In any case, you can use either one. I would go with the 5w30 because it services both your top and bottom end of your engine and is better for it in the long run. I would also recommend using a full synthetic or a blend as well to keep down the deposits and keep power in the engine.
