[QUOTE="pam312, post: 31596, member: 25403"] Hi all sifus......just today, i went to my regular mech to change a couple of things since it was almost time...first off.....my intention was to change the 2 belts, tensioner and pulleys.While at that, found that my fan clutch wasn't in good condition as the coolant temp was consistently reading about 105 degrees and the electric fan keep kicking in more than usualat the same time changed the water pump, two water hose (the ones under the intake manifold), thermostat and expansion tank.....since there was indications that these items needed to change, so I changed it before it really breaks down....all is good......coolant temp now is at 95 degrees and when i drive on d highway, d temp drops to about 85 degrees there abouts....engine felt lighter...i wonder why since there wasn't any mods donethe thing that i really felt strange was the engine growled abit louder than usual....it sounded abit like a high pressure air being sucked in...idling is very quiet, but the moment i rev the engine more, the growl gets louder......is it normal? i didn't had a chance to compare as under my care, this was the first time i changed the fan clutch [/QUOTE]
