Hi, I've recently bought a 2.2 murena that needs some love and renovation. As far it's going quite good, although I've encountered a few problems:
1. I am not sure where exactly to mount the radiator and can't find anything in manual, part list and pictures on google. If someone could provide some info or pictures about I would be really grateful.
Hello Kul,
The radiator is mounted on four right angle brackets that are welded to and therefore part of the chassis. You can only see these either from underneath or when the front glass fibre tub is removed, as in the photo Anders has posted. Are these brackets still in place on your car? Also do you have the correct original Murena radiator with the plastic end tanks with the four moulded corresponding brackets to mate with the brackets on the chassis? I ask this because Murena radiators are rare and if the car you have bought does not have the correct radiator, you may be wondering how it mounts because, unknown to you, it may not be the correct radiator.
How is it mounted currently? Pictures here might help us, but make sure the photos are not wider than 1000 in resolution.
2. Taking out rear brakes is shown only with some special tool that I don't have, is it possible to do it same as the front ones just using longer screws to push the hub out?
First, what special tool are we talking about? Please name it and provide its number. Also have you downloaded my brake manual? (the one Anders pointed you to in his posting) Please make sure you have the latest copy which is dated August 2024 and is the 11th revision. My fault here as I noted I had not uploaded it before but it is definitely there now.
Your statement 'taking out the rear brakes' does not make it clear what you are trying to do. Are you trying to remove the pistons from the rear calipers? If they are seized in, and you have removed the calipers from the car, or maybe have some spare old calipers you wish to overhaul, then first you need to remove the alloy calipers out of the steel yokes, which will ease the pressures on the pistons. Then you connect a grease gun to the caliper, where the brake hose normally connects, and pump grease in to force the piston out. This does not need you to strip off the hand brake mechanism first, but if it is still in place then the internal self-adjusting mechanism has to rotate around the central screw pin, but unless it is seized this will happen automatically.
The second part of your statement describes 'using longer screws to push the hub out'. Pushing the hub out is not part of removing the hydraulic brake pistons, which further confuses me as to what you are trying to do. Are you really trying to remove the rear hub from the semi-trailing arm because you wish to replace the rear brake discs?
Please describe exactly what is wrong which you are trying to repair because if you wish to remove the rear hub to replace the rear brake discs, you are going to have to remove the complete semi-trailing rear arms from the car first, because when you remove the rear hub, the bearing will come apart and you will need to replace it. To replace a rear bearing means having the semi-trailing arm off the car, removing the large circlip and then pushing the bearing out, which will need to be done on a hydraulic press as it will take possibly about 20 tons pressure to start it moving!
