Question about Cadillac CTS

1 Answer

There appears to be a large bolt with an allen recess which may hold housing to engine block. I have already removed the two other bolts and does not want to come off. If this large bolt does go to the block it would have to have some type of flow through design. Is it necessary to remove this large bolt? 2003 cts, 3.2

Check this out to see if it is your engine, you shouldn't have to remove any bolts for the filter. It should just unscrew like a throw away filter, it is a canister type, check it out. Hope this helps.

How to remove cv joint... can't get it off...

remove the large nut for the axle. remove the 2 bolts holding the strut to the knuckle. . you can also remove the tie rod end from the knuckle but iirc it can be done without doing that step. Then take a hammer and punch and drive the axle out of the hub. be careful not to hit the shaft with the hammer directly. this can damage the threads. The inner joint you pry out and then you can pull the axle out.

How To Remove A Manual Transmission From A 1986-92 VW Jetta/Golf

Disconnect and remove the battery. Remove the axleshaft nuts on the spindle and remove the 6 splined bolts holding the axleshaft to the transmission yoke. Jack the car up 1-2 feet. You'll need to support the motor with a jack or jack stand. Drain the transmission, there is a 17mm allen plug at the bottom of the housing. The filler plug is on the right end of the transmission, (17mm allen plug also) to the right of the throw out bearing housing plug, that says VW on it. Remove the axleshafts. Unplug the back up switch. Remove the starter, that will also disconnect the motor/transmission mount. Disconnect the clutch cable and shifter linkage attached to the transmission. Remove the speedometer cable. Unbolt the rear transmission mount (17mm bolt going vertically down, a real long extension will help to get to that one) and bracket going to the end of the transmission at the top, 2, 17mm bolts with nuts. Remove the bracket. Remove the lower inspection sheild, 3, 11mm bolts. From the underneath side, on the other side of the motor where the transmission joins the motor, there is a 19mm bolt holding the transmission to the block, remove that, and also remove the small inspection plate above there, 2, 10mm bolts. Unbolt the two top bellhousing bolts, and it's ready to remove, pull the transmission away from the motor 2-4 inches to clear the input shaft from the clutch disc, you'll have to kind of turn and twist the transmission to get the transmission to clear the sub frame. Also moving the engine up or down will also help. The transmission weighs about 70 pounds.

Where are the timing marks for a peugeot 1.9 td 306


Hope this is helpful, if you need more info get back to me.

1, park car, handbrake on
2, loosen drivers side front wheel bolts,
3, crawl under car use 22mm socket and breaker bar to loosen the crankshaft pulley bolt, it'll probably be quite tight, once undone nip it up again not to tight,
4, open bonnet,
5, jack drivers side of car up, put on axle stand
6, remove wheel
7, loosen and remove intercooler bolts, then intercooler
8, find 6mm allen key
9, behind the starter motor there is a hole in the gearbox housing, put the allen key in it, (may be easier to undo and remove the 3 starter motor bolts)
10, get a 22mm socket put it on the crankshaft pulley bolt, turn the crankshaft bolt clockwise whilst at the same time pushing the allen key into the hole (easier with an assistant but can be done solo) keep turning until the allen key drops into the hole(you'll understand when you do it, may have to turn the engine for quite some time reasonably slowly),
11, thats the engine now on it's timing marks,
12, now put a trolley jack and block of wood under the sump and jack it up until it takes the weight of the engine,
13, remove the left hand side engine mount, basically move the fuel primer to one side, remove the rubber bung if there, then carefully undo the 4 5/8 size bolts and remove the top half of the mount (careful engine doesn't suddenly slip of jack and trap your hand),
14, now remove the 10mm bolts holding the front cambelt cover on, then do the same for the rear cover, except there is one bolt at the back of the cover which is 11mm,
15, now looking at both of the exposed pulleys you will 2 timing holes with a threaded insert behind, on the cam pulley it's at about 4 o clock and i think 2 o clock on the fuel pump, now find the 2 short bolts from the intercooler, they are the right size to fit in the timing holes,
16, now under the arch, remove the crankshaft pulley bolt and pull of the pulley,
17, now remove the lower cambelt cover, all 10mm bolts,
18, now look at the new belt tensioner and you'll see a square hole in it, find the same hole on the car, a short 3/8 socket extension will fit in there and you can then use a ratchet to apply or release the tension,
19, undo but don't remove the two bolts holding the tensioner, now use your ratchet to push the tensioner towards the windowscreen, whilst holding it there use your other hand to release the belt from behind the tensioner,
20, with the belt now loose remove it from round the rest of the components,
21, now replace the waterpump,
22, now replace both the tensioner and idler pulley, to do this you'll need to remove the rest of the metal engine mount, the bolts are quite obvious,
23, replace the belt in the same manner you removed it,
to tension the new belt pull the ratchet towards you then tighten the tensioner bolts at the same time,
24, with the tensioner tightened push the belt in the middle between the two pulleys you should have about half an inch of deflection if correct (check the old belt before removing to give you an idea),
25, now remove the two timing pins in the pulleys and the allen key,
screw the crankshaft pulley bolt into it's hole (leave the pulley off) if you keep screwing it in then the engine will turnover,
26, turn the engine over by hand at least 8 times, then put the timing pins back in as you did at the start, if you've done it all right it'll turn over with no issues
27, recheck the tension again,
28, if alls well then refit the lower cambelt cover,
29, refit the crankshaft pulley,
30, refit everything you've removed, torque all required bolts correctly (except crankshaft pulley which is done last)
31, remove the allen key (2 intercooler bolts will have already been done when fitting the covers and intercooler,
32, turn the engine over again by hand to check there's no rubbing on the cam covers or any other issues,
33, if alls well then top up the engine coolant as you'll have lost alot when doing the waterpump, bleed it properly,
34, put the road wheel back on, lower the car to the ground then torque up the crankshaft pulley bolt,
35, job done start her up then tidy up

How replace thermostat

Follow the upper rad hose to the engine and that housing there contains the thermostat. It is kind of hard to get to but it depends on you. Be sure to put the spring on the new thermostat TOWARDS the engine. 3 tools should be needed for this job..screwdriver (flat head), 8mm deepwell socket w/extensoin and maybe some pliers to rotate the radiator hose clamp away from 1 of the 2 bolts required to remove the t-stat housing. Step 1. remove the airbox assy. just loosen the clamp with a screwdriver at the throttle body, a pull back the airbox assy and unhook all the elec connectors. under the throttle body you will see the radiator hose leading to the t-stat housing. it's a little tricky to get to, but should not be a problem if the hose clamp is not in the way of one of the bolts. if it is, just rotate the clamp by sqeezing it with pliers. (that's the hard part) but hopefully it won't be in the way. step 2. remove the bolts with an 8mm deepwell socket. you'll need a deepwell cuz the bolt on the left is also used to hold a clip for the spark plug wire holder otherwise known as a "stay". REmove the plastic stay to get to the bolt. then remove the 2 bolts and pull the housing back with the hose still connected. step 3. remove t-stat and any gasket material so that both surfaces are clean. step 4. replace t-stat and gasket. use gasket sealer with the gasket that comes with the t-stat.. re-assemble everything and you are done.
NEVER EVER REMOVE a radiator cap from a
What to look for:
  • If the vehicle has a radiator cap - run the engine with the cap off and watch for coolant flowing past the opening. This is a good thing - the thermostat if fine

    CAUTION If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up. Be ready to put the radiator cap back on.

  • Feel the top of the radiator hose to confirm that the coolant is warming up. If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
  1. Drain enough coolant (into a clean container) to get below the level of the thermostat housing
  2. Remove the upper radiator hose from the thermostat housing. See TIP below
  3. Remove the mounting bolts and remove the thermostat housing.
  4. CLEAN BOTH SURFACES of ALL gasket material! Any gasket left behind will likely cause a leak.

    * Compare the size of the thermostat to the old one - make sure the new one matches up
    * Ensure the thermostat fits into the groove in the block or outlet housing.
    * The spring side faces the block - If the thermostat is installed backwards, the engine will overheat

  5. Install the gasket - DO NOT USE RTV sealant

    NOTE - When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

  6. Reinstall the thermostat housing bolts - tighten evenly

Wanted to know where the thermosstat is located on the engine

Follow the top right large radiator hose to the block. The hose is attached to the thermostat housing which is bolted to the block. As you may suspect, the thermostat is located in the thermostat housing. Remove a couple of 10mm bolts and two 13mm bolts.
