You can remove the fan clutch to add additional space. 1.8 T or V6? On 1.8 T remove the turbo hose. You have 2 types of fan clutches. Usually a big nut on the fan which must be removed by blocking the pulley or holding it and turning the big nut as to tighten it (opposite threads.) Usually seized on a little heat is needed on the nut just being careful not to heat the clutch and damage it. Other model have an 8 mm allen in the back depending on the fan clutch. With this advanced you'll have more space to move the fan a little. If you have to remove the front it's really not as bad as you think. About 1/2 hr it'll be advanced. You don't have to take it all off just advance it without removing the rad hoses or a/c or radiator.

There is a shortcut but I cannot remember what it is. My alternator failed and the AA engineer and myself struggled to remove the alternator, but when we collected the new unit from a VW garage the mechanic gave the AA guy some tips as we didn't want to remove the whole front end. 
Apologies for not being more helpful, but it can be done.....

How do you change the alternator and replace it with new alternator, for a 2003 Nissan Altima, with a 2.5 L engine ?


The alternator is right on top of the 2.5L motor and held on by 2 14mm bolts. To remove the lower bolt (hard to reach), you must remove the coolant bottle and the IPDM fuse board and its metal box/bracket. A breaker bar really helped give enough torque to loosen the 2 bolts. Approach the drive belt from under the front passenger tire. There is a tension adjuster (hard to reach) bolt that loosens the belt and allows you to remove it from the alternator. If the belt is still good, (don't remove entirely) save time and try to keep the belt in a similar position. I am not an experienced mechanic and job took me about 3 hours & $200 for the alternator.

Pulling an alternator


Removing the rear-mounted alternator on early 1990s Civics and CRX can be frustrating. After removing the upper adjusting bracket bolt and the lower pivot bolt, the alternator can *almost* come out the top and almost fits behind the intake manifold.

The only easy exit path is out the left wheel well. Side access requires removing the wheel and unfastening three of the plastic retainers holding the upper end of the splash guard. But even this doesn't provide quite enough room. You need to tuck the alternator back under the intake, unbolt the lower alternator bracket (two bolts, 14mm socket) before the alternator can be removed.

The tools needed:

10mm socket -- alternator power connection, battery terminal
12mm wrench -- adjusting bracket
14mm socket -- adjusting bracket, pivot bolt, alternator bracket

Replace 1997 civic ex alternator


The alternator is removed from the bottom of the vehicle. place the vehicle on jackstands positioned on the body, so the suspension hangs (you'll need this extra clearance to get the alternator past the axle shaft). 1). Disconnect the battery 2.) remove the upper mounting bolt (12mm) 3.) remove the terminal nut from the white wire. (10mm) 4.) Disconnect the 4pin connector 5.) From under the vehicle remove the lower mounting through bolt nut and through bolt (14mm) 6.) Remove the alternator from the lower mount and position the alternator to the side of the lower mount. 7.) remove the two lower mount bolts (14mm) and remove the lower mount asy. 8.) remove the alternator down the axle and out below the wheelwell. its going to be a tight fit so you'll have to turn the alternator at just the right position to get it out.

I need to replace the alternator in a 1996 Dodge Grand Caravan


Disconnect the negative battery cable with a socket wrench. Remove the windshield wiper module for 3.0 L and smaller engines or the right front lower splash shield for engines larger than 3.0 L. Remove the accessory beltdrive with a socket wrench. You will also need to remove the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if you have an engine larger than 3.0 L.
Take the mounting bolts off of the alternator with a socket wrench and disconnect the alternator's electrical harness. This will allow you to remove the alternator assembly.

Install the new alternator assembly and connect the electrical harness. Tighten the mounting bolts to 40 foot pounds with a torque wrench and install the accessory drive belt. You will also need to install the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if your engine is larger than   3.0 L.

Connect the windshield wiper module or right front lower splash shield as required. Connect the negative battery cable with a socket wrench.

Good luck and hope this helps.
I have heard the easiest way to remove the alternator is to remove the exhaust manifold. It will cost about $15.00 or so for a new manifold gasket but it is supposed to create enough room to be able to swap it without the hassle of removing alot of parts.

You'll have to rock the alternator back and forth to get the bushing that the lower bolt goes through to slide back enough for the alternator to slide out.
