Couple things: These evidently are prone to a coolant leak that is either gasket or crack in intake. Other thing is that bypassing the heater core(s) can be problematic because the flow to it isn't as easily accessible if you want to bypass it. The return is a metal tube that goes under the intake into the back of the pump. Its all doable, just not the two minute job like on most engines. Seems from what I am seeing and reading on here, lots of simple maint can be a pain because the engine sits so far back and stuff is hard to get at.

2001 XLT, bought it new December 2000 with 8 miles on it. I have 387,487 on it now. This week, I replaced the rear wiper motor (Missing teeth on the flywheel). I am dealing with two minor issues at the moment. 1. After putting on a fresh new air suspension pump/dryer from Arnott, I've begun to develop an occasional loss of air. This might happen after a week, or it might happen overnight, or it might happen in a couple hours. you never know when it's going to drop on the rear tires. The pump works perfect to inflate the bags back to normal and never operates while driving. 2. I'm getting some torque converter slop while going 35 - 55 mph. The tail shaft on the Transmission has slack.
Mobil1 synthetic oil changes in same engine. transmission replaced at 210k.

Changing that heater core isn't a bad job; I did it in about four hours. There's a few good videos around. My 2000 that's for sale has 214,000 and runs like a champ.

97 EB at 240K, due for suspension rebuild (have all of the parts to replace aging air system, just need time). 00 XLT at 212K, replaced intake at 201K, also plugs, hoses, water pump, IAC, EGR, and any seal or gasket I could get to. Both have 5.4 auto 4x4 and broken vent doors. Bought the 97 4 yrs ago for parts and have been driving daily since.

My wife’s 2003 225k on the clock.
Original engine and transmission.


My 97 210k on the clock bought used so don’t know the history of drivetrain...

Both run very well.
Both are daily drivers. My wife uses hers for family transportation.
I drive mine to and from work.

230,000 miles on my 5.4l. I've owned it since 174k miles.

Just changed the radiator (it's been at least the 3rd radiator in it), transmission fluid and motor oil. Seems nice and solid and ready to continue on for another 230k miles.

Put a ground strap on that radiator and the car will stop eating them. Then check the head gasket right above the starter for a water or oil leak. Change the exhaust manifolds yet? You will.
