1989 Ford Mustang GT has been sitting for 5 years

Just bought a 1989 Ford Mustang GT 5.0, 5 speed. Its been sitting for
about 5 years. Aside from the leaking heater core, it seems to run
great with 132k miles on it. Anyone have any insight on what to watch
out for? I'll definitely be changing the fuel filter, oil, etc. I'm
worried that varnish has formed in the fuel tank and fuel system. What
should I do before I drive it?

Thanks

Byron

Well, according to recent posts to this group, you really need to
watch out for a leaking heater core...

You're correct to worry about varnish in the fuel
system. Run a can of Chevron Techron, B-12
Chemtool, or Sea foam through it.

Otherwise, just routine maint stuff.

I would recommend the BG 44K for the fuel system cleaner. All the BG
products are very good, IMO.

What you do in many ways depends on where you live. If you live in an
area that requires emissions testing that is one place I would start.
Get an emissions test and see what it tells you. I would change ALL the
fluids. That means engine oil, coolant, transmission fluid,
differential oil, brake fluid etc. Then check the brake pads, disks and
drums for wear. A wheel alignment might be a good idea. Also, check
for fluid leaks. I do this by placing a large piece of cardboard under
the engine and transmission. Pull the spark plugs and check them, the
distributor cap and check the contacts for corrosion, check the coil
wire connections for corrosion on both ends. Check the air filter.
Also, I would check the condition of all the vacuum hoses, coolant hoses
etc. for excessive aging. It might not be a bad idea to check the
condition of the radiator before summer get here.

you may want to get a new set of tires, 5 years on the ground is not good in
one spot
I got some summer performance tires, they work great.
I would replace the plugs, rotor.
When reinstalling the plugs use that silicon grease on the electrical
replace battery
Check the hoses for age, cracking and replace.
Check the fuel vapor canister vacuum hose (passenger side front of engine
compartment low)
Replace Belt
Have the injectors cleaned at a shop, jiffy lube
Listen for the throwout bearing (high pitch squeaking with shifting, clutch
job then)
Check the small tubes of the emissions system (passengerside firewall in
corner)
I would replace the fluids after 2k miles again
