My hood struts on my 1990 bmw 5251 need replaced .easy job ?

the bmw 525I/530I ( E39) 2.5 l/3.0L engine id25 6S,30 6S (m54) 2001-2003 does not identify as an interference engine so there should not be valve damage
it is chain driven and you will need special cam shaft tools , tensioner locking tool and other special tools to do the job
basically a job for professionals with the correct tools and bmw knowledge
the first inexpensive job that you can do is to check that the chains haven't broken and that the cam shafts are rotating
next is a compression test to determine if the valves are in good condition
if that is good ( 155 -165 PSI) then run the fault codes to determine what may be failing
after that you will know if it will be expensive to repair

STOP what you are doing before you damage something!! Whatever you are trying to remove is not the water pump. Neither the sparkplugs nor the "timing belt" cover needs to come off. Remove the fan belt. Remove the fan (the nut is LH thread- means it turns left to tighten and right to loosen). You will need a large wrench (32mm) availible at sears.The water pump is directly behind the fan and is held in by 4 10mm bolts.

There's trapped air in the cooling system.

• You need to remove the bleeder screw on top of the radiator when adding water to the expansion tank.
• With the engine running, pour water into the expansion tank till you see air go out through the bleeder screw's hole.
• Just keep adding water until no more air bubbles come out then just put the screw back in place.
• Then fill the expansion tank to it's normal level/line.

Try replacing the thermostat. It is supposed to open when the water temp reaches a certain point usually around 180 degrees. It might be stuck in the closed position.

You will need fuel line block off clamp

No not without special tools Not a job for people without a lot of experience.

i would suggest they mean a torque wrench.... yes i know i should use one on pretty much anything i work on but i don't.... as long as you install the new pump with the gaskets properly fitted.. you'll be fine.... it always amazes me how many strangers can do the job i'm doing better then i can

Please take a moment to rate this solution thanks

are you changing the strut cartridge or the whole spring unit? if you are installing the whole unit, spring and all you will need no special tools, if not you will need a spring compressor

The best thing to do is tuen the key on and teat all the fuses with a 12 volt test light. Replace any fuse that test bad.
