  1. Well Mr Obvious... hehehehehe Its a motor that is sued to open or close hidden headlights or the passing 3rd eye. They can be electric or vacume operated. I dont know which onw sooby uses, as i never had a need to replace one. nipper
  2. i use synthetic engine oil. Every 7,500 miles i change the oil as i do lots of short trips. Every oil change I do a drain and fill. This always keeps some fresh fluid in there, and saves me alot of work (as i am already under the car). But thats just me. Oddly i left out blinker fluid.... nipper
  3. Lets look at the fluids under the hood; Antifreeze - in an ideal world can last for the life of the car if it is pure antfreeze. In modern antifreeze you have lubricants and anti corrison chemicals that wear out. These chemicals also make sure there is no electro-chemical reactions between all the differnt materials in the cars cooling system and to keep from eroding parts from physical friction. The coolant is exposed to (for an engine) fairly moderate temperitures. Engine oil - Exposed to hell. It is exposed to extreemly high temperitures as well as low tempertiures. It sees very high pressure (not from the pump, but by acting as the cushion in the bearings. It is desgned to capture dirt and hold it in suspension untill it goes through the filter. It is also exposed to gasoline and its additives which will thin it out over time. Brake fluid - Exposed to high temperatures (can be as high as 650 degrees). Every time the Master Cylinder is opened it absorbs water from the atmosphere. It also protects against corrosion. Now transmission (hydraulic fluid) - used in the transmission and power steering. In comparision it has a rather charmed life and unlimited shelf life. Hyd fluid primary job is to transmit force, its secondary job is to cool and lubricate. Since automotive transmissions have thier oils dictated by the mfg, the viscosity is not a worry (yes hydraulic fluid does have viscosity specs). They all have anti corrosion aditives ( a minor problems as I have yet to see the insides of sealed transmission corroded), antifoaming (critical). Tranmsissions are basically sealed, but other properties are the ability to seperate water out of the oil (more important in construction equipment). Every wonder why modern cars seem to have sealed transmissions (those sticks can be a PITA to get out sometimes), its to keep the enviorment out. BMW has gone as far as sealing thier transmissions. There are some detergents, but since the fluid lives a charmed life they are not that important. Once a transmission starts to make sludge and the things dtergents protect against, its generally a mechanical fault or lack of maint then a failure of the fluid.Transmission lubricant generally does not operate at high enough temps to cause varnish (as long as you dont do heavy duty driving or the clutches dont slip). Interesting factoid, every 18 degrees over 140 F you can cut the life of your tranny fluid in half. Rule of thumb with a tranny/hydraulic fluid temp gauge is that the oil should not exceed more then 100 degrees hotter then the air temp. Over 140 the additives start to break down. Dirt is not a problem in transmissions (this is why i hate transmission shops). All trannies will shed material. This material will collect in the bottom of the pan because that what it is supposed to do. Engine oil will hold particulates in suspension and let the filter take out the dirt. transmissions are the opposite. i can sell a trannny job to almost any unsuspecting person that walks in off the street if i wanted to. When you add fresh fluid, that fluid gets mixed in with the old fluid. You are adding fresh additives at this time. Depending upon your math, you are replacing 20-25% of the fluid on a drain and fill. The new fluid mixes with the old fluid (assuming the fluid is not burnt). Also since the fluid lives a charmed life it doesnt take much to give it what it needs. Its not contaminated like antifreeze/oil/brake fluids can get. You may have noticed that soobys shift hard. The harder a tranny shifts, usually the longer it will last. Soft shifts mean the clutches are slipping. SLipping clutches under load can easily make high spot temps for the fluid. The synching of the shifts with engine torque reduction at that split second of engagement, have trippled the life of a transmission, along with better clutch material and seals. I dont think i am explaining this well, as i hate NYE (long story). Does that help?
  4. Leave it alone, why bother tempting the automotive gods. Now if you really rteally want to do this regularly, every other oil change do a drain and fill. Hydraulic fluid, unlike other fluids, get refreshed when new fluid is added. nipper
  5. I had one self destruct in a nissan i had, It had a small leak i figured i had a week or so, then a noise, a bang, dashboard lit up like a christmas tree. Get home pop the hood, and no more water pump. Just some broken pieces of metal. You lucked out. Do i dare ask how old that pump was? nipper
  6. Does it smoke at all, could be running too rich at full throttle? nipper
  7. 323,000 km (200,700 miles), the car is entitled to drop a few mpg. At that mileage it may be time for a compression test to check the overall health of the engine. nipper
  8. Or do it the way they used to do it back in the good old days, find an Olds Toronado drive train Imagein 500 cubic inche mid engine brat.... EEK nipper
  9. Easier to just flip the differential as alot of modern engines can no longer run backwards. nipper
  10. Maybe a rare combination of a seized AC compressor, but it is full of freon or a seized clutch. Just thinking about it. nipper
  11. I think you have a combination of issues here. The simplest may be a bad blower motor. Its unusual for the switch to go bad, but it happens. You can have an AC issue. Defrost runs the AC compressor (and is probably the clicking your hearing). You may be low on refrigerant. The Air direction is controlled by little electric motors, the defrost door may be broken or jammed, though usually defrost is the default position if anything goes wrong with the doors. nipper
  12. Ok no more speaking of that heathen vehical. 2 mpg can just be seasonal. Blu drops that much in winter and summer (cold vs AC use) and can actually hit 30 on the highway spring and fall. In the winter he can go as low as 16 from his usual 21ish. nipper
  13. From what i remember its on the passenger sidebetween the glovebox and the body. nipper
  14. Blus o2 sensor finally reste, and my gas mileage is back up to where it should be, so yes they will do that nipper
  15. and im a little leery of recomending that much work on a high mileage engein, even a sooby engine. I would hate to see allthat work done and have you end up with blowby. Also this may be chicken vs egg. Check to make sure the cam with the broken gear spins freely, as it may have siezed first. It's rare but it does happen. nipper
  16. No now its done electronically. It operates differntly then the traditional hill holder. nipper
