l am soon to purchase Mercury Grand Marquis between the years 1992 -2001. It has 4.6L V8 engine, 240hp. Will the towing of the boat be hard on the car is engine/transmission?

The towing trip is approximately 4 miles each way, to the Bay, 4 miles return home.

1 mechanic here informed me to install some type of cooling device to the transmission which will make the transmission last longer while towing.

Thank you to all my boating/car friends who submittedto my previous car/towing questions, as after reading your , the Ford Taurus was quickly deleted from my car consideration list.

Thanks - Curt

More than likely the drivetrain can handle it, but l would be more worried if the hitch & suspension of the car could handle the added weight. You will need to find out the Gross Towing Weight capacity, & then make sure the trailer & boat & any additional gear in the boat weighs less than that. Then u will have to get a trailer hitch that can match that towing amount. l agree with the trans cooler. Lower trans temp=Longer trans life. l towed an 1800 pound U-haul trailer with my 87 Mustang, & it only had a 2.3L & an automatic with a cooler. l know l was working that little 4cyl, but it pulled the hills better than the big rigs.

It is rated for 1500 pounds, so probably not.

The Subaru Legacy can tow more than that for fuck is sake.

edit: Whoever voted this down, check the links. The Grand Marquis IS only rated at 1500 pounds. The Subaru Legacy is rated at 2700. The HYUNDA l ELANTRA with the right options is rated at over 3000. Body on frame or not, the Panther platform is not that great for towing.

It will tow 3500 lbs without a problem. It is a full frame car and has plenty of power.

It will tow it just fine just do not tow in overdrive

Not too far.
