So, i'm going to look at an 87 5.0 tomorrow, and hopefully drive it home. My question is, what kind of maintenance things should I do to it once I get it, such as a tune up and oil change?

Thanks.

How thorough do you want to be??


When i buy a used car with decent miles on it, i usually replace and change anything i can.


So if i were to buy a Fox, i would do this when i got it home.

Oil change with Motorcraft FL-1A and quality oil
Plugs (Autolite 25 coppers @ 0.054") and wires
cap and rotor
FUel filter
PCV valve
Check and set timing to 10 degrees BTDC (for now)
Flush and replace coolant
Trans fluid
Rear end fluid
bleed brakes (nobody ever does this) and inspect rotors and pads and drums (replace if bad)

Run check engine codes and see if the car has anything it doesn't like and then fix/replace as necessary.

i'd do a quick search and learn the common problem areas on these cars if you don't know them already, BEFORE you buy it. it could save you a lot of money and headaches....

StangNet's favorite TOOL

My standard newbie welcome...

Welcome to Stangnet...

Not all of us know how to fix everything, but some of us know how to fix some things with excellence!

If you want to do the fix up & power up thing, make sure that you have some other form of reliable daily driver. That way the stang can sit while your wallet and hands take a rest from the last project that didn't quite get finished on that 3 day weekend. Things always cost more and take longer the first time you do them. Having some other working vehicle makes life easier since it isn't the big crush to get it running for the Monday morning drive to work or class.

Plan on spending some money on tools it you don't already have them. The stang has both metric and american fasteners, so you really need two sets of wrenches. A timing light, digital voltmeter, vacuum gauge, compression tester, fuel pressure test gauge and fuel line coupler tools are some of the test & tuning tools you'll need. Visit the pawn shops and sometimes you can find a deal on tools & test equipment if you stick to well known name brands.

A sheltered work area is almost a must, someplace that you can leave the car in pieces without upsetting anyone. Some guys here have changed a transmission in the parking lot of their apartment in a rainstorm, but they will tell you it wasn't fun. Depending on where you live, a warm dry garage is a nice place to do the winter projects that stangs tend to become.

EFI (Electronic Fuel Injection) Computer - every stang after 85 has or had one: don't let it intimidate you. The computer based EFI systems are not hard to fix and most of the time they tell you what's wrong with the engine. Here's a book that will get you started with how the Ford electronic engine control or "computer" works.

Ford Fuel Injection & Electronic Engine Control 1988-1993 by James Probst :ISBN 0-8376-0301-3.

It's about $25-$30 from Borders.com see http://www.amazon.com/ . Select boo...d.php?t=643651"]Useful Technical Thread Index” sticky at the top of the 5.0 Tech forum.

Things that break often:
T5 5 speed manual transmission (syncros go bad, mostly 3rd gear)
TFI Module (Thin Film Ignition module - mounts on the distributor)
Electric door locks (see the link in my sign for a cheap & easy fix)
O2 sensors(oxygen sensors) They are good for about 60,000 miles and start to go down hill after that.
TPS Sensor (Throttle Position Sensor) causes flaky problems with idle & acceleration.
Fog lights They overheat the wiring and cause the headlights to flicker. The fix is cheap and simple if you can do electrical stuff.
Harmonic Balancer – they separate between the hub and outer ring. A harmonic balancer puller is a must have to change it. You can rent or borrow a puller from most of the larger auto parts stores.

Things that are very durable:
Engine - as long as it hasn't been abused, it will run good for 150,000-200,000 miles without an overhaul
Rear axle other than an occasional case of worn clutches in the traction lock, they almost never have problems.
Computer - believe it or not, the computers seldom have problems of their own. Most of the problems are with the sensors and the wiring.
Suspension – the front and rear suspension has very few problems if the car hasn’t been wrecked or seen a lot of drag strip runs. The drag strip runs tend to distort and tear the mount points for the rear axle control arms. Revving the engine up to 4000 RPM and dumping the clutch with slicks or drag radials tends to break things.

Things that don’t break often but are hard to fix:
Water pump mount bolts – they corrode and shear off when you try to change the water pump.
Rear oil seal on the engine – lots of parts to remove to get to a $20 seal.
Power steering pump – the pumps are noisy and the pulley requires some special tools to remove and install. If you have the tools, they are easy to do. Again, the larger auto parts stores will rent or loan the tools for the pulley.
Power Steering rack - it is hard to get the toe in set so that you can drive the car to the shop to get it properly aligned.
Starter – the top bolt is hard to get a socket on if you don’t have the right combination of socket, universal joint and extensions.

Everything considered, 5.0 Mustangs are not hard to work on. They just require some patience and though before you get started.

Good

+1 on everything mentioned already especially the posts by Mustang5L5 and jrichker.

The only other things I would add are to look over all your vacuum lines really well and look for cracking, rotting and check the tires really well too for dry rot and cracking.

Also, re-tighten all the lug nuts just to be safe.

To me the these items are absolute must change and very easy to do:

Oil change with quality oil
Air filter
Plugs and wires
Cap and Rotor
Fuel filter
PCV valve
Transmission fluid
Coolant
