I need to know the correct torque specs for the 4 bolts that hold the a/c compressor on my 2003 Suzuki Aerio. In order to replace the water pump it was necessary to remove the compressor. The book supplied the torque specs for the water pump (12 ft. lbs.) The a/c bolts are the same size as the water pump so I assumed the torque would be the same. I crushed the lower left boss which allowed freon to escape. NEVER ASSUME!

sold mine, when suzuki bugged out of USA<
H25 engine that and is a good motor.
hand tight, then go say 10ft/blts in criss cross pattern( generic ASE pattern there)
then to full spec.
I still have s real service manual on this car. at hand so will answer.
or online

Tighten the bolts to 19 ft. lbs. (27 Nm).228 INCH/LBS
best is always read the manual and no get bad answers online
word of mouth answers wreck engines.
top one is torquing M6 bolt to 100fl./lbs and not inch, oops stripped.
100 div. by 12 =8.3 ft/lbs.

The site that has that information is called alldata and it is not free.

First you need to know the diameter of the bolts and the type of thread ie 3/8 N/C or 5/16 N/F then look at the type of bolt ie plain steel or high tensile SAE grade 3, 4, or 6, once you know this go to a general purpose bolt torque chart, and derive the torque spec info.
If the water pump is cast iron use the full torque specification.
If the water pump is alloy then reduce the torque spec 10%

Below is an example of a general purpose bolt / nut torque chart

WOW you work on engines not knowing what is there?
the engines are: 7 engines.!!!
1.3 L I4; 1.5 L I4; 1.6 L I4; 1.8 L I4; 2.0 L I4; 2.3 L I4; 1.4 L Diesel I4 ill guess, ( (die roll)
2.3 L below.

all answers, USA cars, this a USA forum. so.....
ever heard of the FSM the oem factory service manual?

is the chain making noises? if yes, the guide is bad, most chains fail due to that (as a true cause)
the FSM is here , just $4 to look , so ????

the clone is Alldata.com DIY, log in and read like we do.
google alldtata.com , bingo....

now the 2.3L (just the first half, ill let you pay $4 like we do)

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove engine assembly from vehicle.
3. Remove oil pan.
4. Remove cylinder head cover.
5. Remove timing chain cover as follows:
   • Remove crankshaft pulley bolt. To lock crankshaft pulley, use special tool 09917-68221 (camshaft pulley holder).
   • Remove crankshaft pulley. To remove crankshaft pulley, use special tools 09944-36011 and 09926-58010 (steering wheel remover and bearing puller attachment).
   • Remove A/C compressor bracket.
   • Remove alternator belt idler pulley, water pump pulley and alternator belt tensioner.
   • Remove timing chain cover bolts and nut.
   • For reinstallation of timing chain, turn crankshaft so that timing marks on cylinder head and lower crankcase match with those on sprockets as shown in figure.
   • Remove second timing chain as follows:
     
     • Turn crankshaft to meet following conditions.
       
       • Key (I) on crankshaft is positioned as shown.
       • Arrow mark on idler sprocket (II) points upward.
       • Marks on sprockets (III) match with marks on cylinder head. Note that this step must be followed for reinstallation of timing chain.
     • Remove timing chain tensioner adjuster No.2 and gasket. To remove them, slacken second timing chain by turning intake camshaft counterclockwise a little while pushing back pad.
     • Remove intake and exhaust camshaft timing sprocket bolts. To remove them, fit a spanner to hexagonal part at the center of camshaft to hold it stationary.
     • Remove camshaft timing sprockets and second timing chain.
     • warning
     • After second timing chain is removed, never turn intake camshaft, exhaust camshaft and crankshaft independently more than such an extent as shown. If turned, interference may occur between piston and valves and valves themselves, and parts related to piston and valves may be damaged.
     • Remove timing chain guide No.1.
     • Remove timing chain tensioner adjuster No.1.
     • Remove timing chain tensioner.
     • Remove idler sprocket and first timing chain.
     • Remove crankshaft timing sprocket.
     • end.
   im not doing INSTALL, sorry.

got that? also there are a hole section on details of gasket seals and such, nothing trivial that.

go to the library and get chiltons repair manual or buy one. its big job you have in mind and you need to know what your doing or cyour car will be junk. check in your area to see if the high schools have a mechanics trade school you can have your car repaired by students under the supervison of the intructors

doing this without a manual is wrong, you will make very expensive errors.
did you check the head for warpage, do you know how?
the head , bolts are staged in a special order too.
all that and more is here.
capacity varies by casting variances. but there
is an average, and is stated in the operators guide, and here.
Im not affiliated, just love this product. nothing better,
cept the REAL FSM ever consider that book>?

next time state engine displacement and country, for better answers. the world is a big place. no?

special tools you need EN 48543 FAN CLUTCH HOLDING TOOL. J41240 FAN CLUTCH REMOVER AND INSTALLER. TORQUE FOR FAN CLUTCH NUT 41 LB FT. FOUR BOLTS TO FAN BLADE TORQUE 20 LB FT.WATER PUMP BOLTS TORQUE TO 11 LB FT. DONT NEED SPECIAL TOOLS REMOVE WATER PUMP.

Hi! Please don't forget to rate! Thanks!

Cylinder head bolt torque sequence-2.0L and 2.3L engines

Apply engine oil to the bolt threads and tighten the cylinder head bolts, in sequence, using the following 6 Steps:

• Step 1: 38.5 ft. lbs. (53 Nm)
  
• Step 2: 61 ft. lbs. (84 Nm)
  
• Step 3: Loosen all of the cylinder head bolts
  
• Step 4: 38.5 ft. lbs. (53 Nm)
  
• Step 5: 76 ft. lbs. (105 Nm)
  
• Step 6: Bolt M6 (bottom left of cylinder head) - 8 ft. lbs. (11 Nm)
  

Hello nedy...if you have the V6 engine, it will require the removal of the timing chain cover to access the water pump. The water pump is mounted to the engine block with 4 bolts. It is recommended that the bolts be replaced due to electrolysis (steel bolt in aluminum block) Replace all gaskets and o-ring seals as well.
While you are in there, you can inspect the timing chains, it has 3..and the chain tensioners. A Haynes repair manual would be helpful on this project and will have the correct torque specs.
Good luck...i hope this helps, please rate mr a fixya.
