  1. Accy. belt/ drive belt = same thing ;)
  2. Here is what you will need: Tools Needed: Breaker bar or impact wrench Socket wrenches Socket extensions Angled socket joints Torque wrench capable of reading at least 181 ft-lb Sockets 8-22mm + 8mm hex socket Harmonic balancer pulley remover (this can usually be rented from Autozone or buy one) Parts Needed: Timing belt ~$52 Water pump ~$155 No.1 idler pulley ~$98 No.2 idler pulley ~$62 Timing belt tensioner ~$40 Accy. belt Optional Parts to Replace: Spark plugs Spark plug wires Thermostat Distributors Rotors Drive belt Air filter Now find the parts online(shop around) and get the job done.

  4. Thanks. So far. Bought a set of replacement trunk struts off ebay for $75. No more getting clipped in the back of the neck!! Now I need a good OEM repair manual. Also, what's the best way to do a "tranny flush?" Does this thing really hold less than 2qt or ATF? Wow. My suburban takes 17qts for a good, thorough flush!!! The drain and fill is about 2 qts., I wouldn't flush the tranny, Just drain and fill.
  5. Well, So far so good, I went on a 900+ mile trip through snow and rain + dry roads and I am satisfied with the HTR's. Maybe there is a touch more road noise compared to the pilot sports, But not enough to annoy me. We'll see how they hold up if and when the heat comes.
  6. Very nice LS, Very clean indeed B)
  7. Happy Easter to all LOC members
  8. Check the third brakelight in the back window. ;)

  10. No, The wiring is different.
  11. Good Luck, And Welcome to the club
  12. Are the terminals reversed ?

    Overdrive

    Overdrive can refer to two different things. An overdrive is a device which was commonly used on rear-wheel drive automobiles to allow the choice of an extra-high overall gear ratio for high speed cruising, thus saving fuel, at the cost of less torque. It also refers to a combination of gearing inside a transmission or transaxle which results in the output speed being greater than the input speed. In the latter case, "overdrive" does not refer to a physically separate identifiable part/assembly. Early manual automotive transmissions were limited to three or sometimes four speeds, with only the most sophisticated being five speeds. This left an unfulfilled need for a higher gear ratio for highway cruising, which was filled by the addition of separate overdrive units. However, automotive manual transmissions manufactured since the 1980s tend to include a larger selection of gear ratios than before, the highest of which is usually greater than 1:1. This trend has rendered the overdrive a complex and obsolete solution to economy gearing in automobiles, and very few cars are fitted with them today, although they still appear on large trucks, where more gear ratios are always in demand Usage Generally speaking, overdrive (OD) is the highest gear in the transmission. Most automatic transmissions have three speeds and overdrive (fourth speed). Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to realize better fuel efficiency, and often quieter operation on the highway. When it is switched on, the transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [45+ mph] depending on the load). When it is off, the transmission shifting is limited to the lower gears. For normal driving conditions, operation of the overdrive should be enabled only if the average speed is above 70 km/h (approx. 43 MPH). It may be necessary to switch it off if the vehicle is being operated in a mountainous area. The automatic transmission automatically shifts from OD to third gear when more load is present. When less load is present, it shifts back to OD. Under certain conditions, for example driving uphill or towing a trailer, the transmission may "hunt" between OD and the third gear, shifting back and forth. In this case, switching it off can help the transmission to 'decide'. It may also be advantageous to switch it off if engine braking is desired, for example when driving downhill. The vehicle's owner's manual will often contain information and suitable procedures regarding such situations, for each given vehicle. How an overdrive unit works The overdrive consists of an electrically or hydraulically operated epicyclic gear train bolted behind the transmission unit. It can either couple the input driveshaft directly to the output shaft (or propeller shaft) (1:1), or increase the output speed so that it turns faster than the input shaft (1:1 + n). Thus the output shaft may be "overdriven" relative to the input shaft. In newer transmissions, the overdrive speed(s) are typically as a result of combinations of planetary/epicyclic gearsets which are integrated in the transmission. In these cases, there is no separately identifiable "overdrive" unit. A number of such transmissions and transaxles are manufactured by Aisin, for use in vehicles produced by many different manufacturers. In older vehicles, it is sometimes actuated by a knob or button, often incorporated into the gearshift knob, and does not require operation of the clutch. Newer vehicles have electronic overdrive in which the computer automatically adjusts to the conditions of power need and load
  15. I must have overslept, It's Sunday already ??????????????
