Looking at a 2003 Park Ave, things to be done ?
Its got 75k but is real clean. I think i should, if I buy it, Chg;
fuel filter, air filter, tranny fluid and filter, and get the Dex cool out and replace it ith the Prestone mix with all coolant and chg the tstat at the same time, agree ??
Also add a trailer hitch for my small trailer

I always enjoy a good seafoam treatment myself before doing a tuneup. I don't know if a tuneup is necessary though, as I believe they were set up to run to 100k miles before needing one.
I would do a coolant flush though at least. Whether you put Dex back in to it is completely up to you.

And yes, I would suggest a complete cooling system flush. DEX is 5 years or 100k miles, which ever comes first, and that car i well past 5 years. No problem putting DEX back in. But if you don't use DEX then make sure you flush it all out, anything left and it will sludge up. You could also use all color if you wish.
In the midst of all this stuff. I'd suggest lower intake gaskets. Change them out to the newer style aluminum versions. If this is not an Ultra, plug the coolant ports in the LIM while you are there and you should have a long living trouble free car. As for Dex.. it'* not the enemy, the gaskets were the issue.
Bill, Can you plug the coolant ports and use the same UIM ?? How tough a job is that ??
These cars get great gas mileage ! The only thing that seems to be a problem is my 98 Bonnie and my 99 Park Ave both needed torque convertors at 100k miles...
Any way to flush and be sure to get all the dex out ?? If some stays it should be ok with the mix any color coolant right ?

It'* easy to block the ports, 1/4" plugs, tap the holes, put plugs in seal them good with RTV, remove the O rings from the gasket and put a nickel in it'* place and use RTV to seal it good, let dry, then close everything up.
Any color coolant is fine, just drain what you can and refill with any color.
