Jobs that are normally horrible, but on certain cars are easy.

Opposite thread.  
 

Clutch on my Datsun 310GX engine and tranny never move.  Remove upper trans cover, slide gear cluster thru wheel well and unbolt clutch and replace.  

Alternator on my corolla. 3 bolts. It's on top of the engine. 

Clutch on Saab 900 turbo with air. Just remove the hood for access. Now about that water pump.

ACVW engine/ main seal. My wrenching sensei and I once drove a bug in, replaced main seal, and drove it out in less than half an hour.

Literally anything engine related on an ACVW. Even building the thing is quick and easy.

Motor and trans mounts on my E38.  Most cars it's a pain in the ass with wiggling things around for alignment, trying to get to the mounts, etc.  On this thing, you just jack up the motor or trans, find the right set of sockets and extensions for the motor mounts and the right box wrench for the trans mounts and go at it. 

Trans mounts are remove 2 nuts per mount, slide the 2 mounts out, slide new ones in, install nuts. 

Motor mounts are drop undertray, remove 3 nuts per mount, disconnect secondary air pump hose so you don't break it (don't ask how I know that).  Jack up engine, wiggle / rotate old mounts out and new ones in, lower engine, install nuts, connect hose.  All shockingly quick and easy (and surprisingly cheap too). 

Oilchange on w211 e55. 2 drainplugs, no big deal, but the filter is right up top front corner and makes for the World's Easiest Oil Fill.  And though you can't bleed the brakes without a diagnostic computer, you can change brake pads in minutes. 2 bolts removes caliper, 2 spring clips and pins locate 4 pads. Done and done. 

Entire drivetrain on early Corvair.  Engine and transaxle on the floor in about 30 min if you are prepared.  Lates are a bit more involved but not terrible.

I can change the oil on my FR-S without jacking up the car.

Now that I think about it, I can do that on the Focus wagon as well.

swapping the fuel pump on a 1982 maxima wagon was easy because the pump was external to the fuel tank, and the hoses were long enough to clamp with vice grips.

Timing chain on a Ford 4.9 I6...

Never wears out because gears.

Ford Contour V6 water pump. Run off the back of the head, up on top easy to access. I think I spent more time picking up the replacement at the parts store than changing it. 

Engine R&R on any naturally aspirated Subaru.

Early, an hour if it’s your first time, otherwise 30 minutes max.  Late, add 15 minutes.

Coolant flush is even easier.  ;-)

I changed heater cores on my 91 Ford Ranger AND my 91 Escort on the same day.  The easiest AND the most difficult change I have ever done!

You mean they never “improved” them with self destructing plastic gears? 

Pretty much anything on a Spitfire except removing the rear hubs.  And if you have the correct tool, that’s a piece of cake.  

Water pump on an 1982 Subaru w/o A/C or P/S.  You pop the hood and there it is.

I will second this, I could not believe how easy the heater core was on my 89 Ranger.

Oddly enough my prior experience with such things was on an Escort.....

I was going to post a thread just like this, with this very car /job. 

Fuel pump on a 3rd-gen Odyssey.  You know how, on many vehicles, you wish there was a trap door in the floor to access the pump so you don't have to drop the tank?  On the Odyssey, there is one.

Oil and automatic transmission fluid on a Subaru with the EJ22.  You can change the oil from the front of the car without jacking it up.  And the trans has a drain plug and a spin-on filter, both no harder to do than an oil change on a regular car.

Oil filter access can't be any easier.

Single stoutest engine ive ever worked on. Ford built them ridiculously tough.

A Saturn S car ATF change - the transmission has a drainplug and spin-on oilfilter.
