Differences in 99-04 engines

[Mustang5L5]

Consider yourself lucky it has a T45. It's a stronger tranny. Just do a search on the 3650 and you'll see why.

Stronger in what way??


The t-45 is rated at 330 ft-lbs, the t-3650 is rated at 360 ft-lbs. The 3650 is the stronger transmission.


The 3650 just has some shifting issues. The t-45 has issues of it's own. Can't tell you how many of my friends have suffered the "stuck in reverse" problem.


My 3650 shifts fine, and i would prefer it over the t-45 if i ever had the option

hate to butt in yall, but "pump gas" means 87 octane? whats recommended by ford for 99-04, and whats the real truth?

The GT will run on 87. However around '01 there was a slight bump in compression that puts the 01+ right on the border of 87/89

since new, my car has not liked 87 on warm days. In the wintertime i run 87 all day long with no probs, but once summer comes around it will detonate slightly when it's warm (or if i'm driving around with the A/C) As a result, when i know it's going to be 80-90 degrees, i run 89 octane. But when it's cooler (60-70) i can run 87 no prob.

It's done this since new.

Sorry guys. My newb blood is showing through. I have read some negative stuff on the t-3650 and assumed it was not as good as the t-45. My bad.

I think there was also a mid year change on the water pump in 2001?

a 2000gt will use regular (87 octane).

if you look at the intake manifold and it still has the plastic coolant crossover, have them change it to the 01-04 manifolds with the aluminum coolant crossover.

looks like a good deal man, if u can talk em down to 8k that's a steal. If it's still a plastic coolent crossover use that as a bargaining point saying you'll have to pay to change that out anyway.

Whats wrong with the plastic coolant resevoir? I've never heard of anything with that, I have a 2002 that has a plastic resevoir, and my bro has a 2004 GT with the same plastic resevoir. Ive only seen the alum on the cobras. I knew the pre 2002 cars had bad intakes but that's it.

ive been running 91 since i bought it, i wonder if that has anything to do with it overheating on me in 105+ degree heat everyday

spederman: i think theyre talking about the crossover in front of the intake, pre-01 models (or so i believe) come with a plastic crossover, as in the path the coolant takes in front of the intake manifold, not the resevoir on top of the rad. im a noob so dont take this seriously if im wrong

i passed up the bullitt. I couldn't afford the 10,800 they were asking for it, so i decided to drive my 89 until the winter rolls in and mustangs might be a bit cheaper lol. hopefully divorce motors may be opening for business and i get lucky one of these times

I think they are talking about the little cross section that the thermoatat sits in. The early 4.6 this was plastic and prone to crack.

Never wish for another mans misery..

I am without a stang right now because I am trying to buy a house, but I rather be stangless then give some vulture my money for a car that the court system stole from another guy. The car would feel tainted to me.

 

[mrmustangman357]

when i meant divorce motors, I was joking, as its usually the guy that sells off the car before his wife tries to take it in court. Its meant to mean "a deal that isn't an ordinary occurance".
