  1. Blasting the heat removes heat from the coolant. A head gasket leak injects super-heated air directly into the coolant. A bad radiator cap can also cause an overheating condition if the cap cannot maintain sufficient cooling system pressure.
  2. I would take the vehicle to a good alignment shop. I had my Mazda 3 suspension upgraded a few years ago. Last year the driver's side front corner would occasionally thunk when rebounding. I took the car back to the alignment shop (same one that installed the springs and shocks) and they found a loose shock mount, tightened the nut and charged me nothing.
  3. You don't have to, but I had ours replaced since it is removed, anyway.
  4. Hello, everyone. After 13.5 years and 120,000 miles, the hydraulic piston hood support in our RX400h finally decided to give up. Here's what I found: 1. The OEM replacement at the local dealership is $125. 2. Aftermarket ones are $13 - $18, depending upon quantity purchased. 3. Unfortunately, the OEM support is pretty much permanently attached at the lower end bracket and the bracket itself is not readily available. I did find one at a Lexus parts website but the Lexus part number listed was for a rear hatch bracket, and its photo did not look like the one I have. Thus, the aftermarket replacement appears to be a bust. I tried removing the OEM mount from the bracket but it seems the only way to free the ball socket from the bracket's ball is to use a cutoff saw/Dremel disc. Even then, you may damage the bracket pivot ball. I do not advise doing this unless you are well-experienced. 4. The OEM replacement comes with the bracket, The online price is about $75 + shipping. This is what I had to buy after returning the aftermarket supports. (I had bought a 2-pack for $25.) 5. While the OEM support is not assembled to the bracket, its lower pivot ball snaps in fairly easily. Here're the steps required to do the job, assuming you bought the OEM "kit": a) Remove the two engine bay plastic covers - one over the battery and one closer to the firewall. This will allow you access to the support bracket screw. b) Have someone hold up the hood while you use a small flat blade screwdriver to pop out the support's upper pivot socket retainer clip. You don't need to completely remove it - just pull it towards you a bit. If you get carried away and cause the clip to fly off in a dark corner of your driveway or garage, you can always use the old one. c} Swing the support down and remove the lower end bracket's screw with a 10mm socket and ratchet wrench or box end wrench. Be careful not to let the screw drop down into nevernever land. Place the old support assembly away from the engine bay. d) Pop the new support's lower pivot socket (the one that has no retaining clip) onto the new bracket's pivot ball. Install the bracket and its screw, and then back out the support's top pivot socket clip as you did to the OEM's clip. e) Pop onto the upper pivot ball, the support's pivot socket, reinstall the plastic covers, and lower/raise the hood a few times to verify proper operation.
  5. Steve, have you already perused Autotrader.com and craigslist? I'm not sure why you are excluding the 2006 model but I can tell you that they, too are very reliable vehicles.
  6. You are correct in that the Audi is not very reliable after its warranty has expired. Do you really want the safety features available in the newer Lexus vehicles? There are quite a few that are very useful - laser cruise, backup proximity sensor warning, and blind spot warning are my favorites. If these are not must-haves, you could get quite a few miles out of your current vehicle. A sales guy at our dealership told me he has seen many RX400s with well over 200,000 miles on them.
  7. Have you first unlocked all the doors by pressing the key fob's unlock button twice. You will hear beep-beep, then beep-beep again. If you hear the double beep one time, the rear doors are not unlocked. All doors must be unlocked before the power tailgate lift will function.
  8. Have you tried any of the online Lexus dealership parts sites? Perhaps you can get a more accurate manufacturer's part number. Some of these sites ask you to enter your vehicle's VIN number to make sure the part will fit.
  9. While the Audi is highly rated by Consumer Reports, I have noticed that most models show increasing reliability issues after 4 years or so. The Lexus F-sport versions do bump up the handling performance, so that may be an option as well. The most compelling reason I would have to upgrade would be the safety features - especially the back up proximity warning and the convenience of laser-cruise.
  10. You should have the AC refrigerant checked. If there is a leak somewhere in the AC system, your air conditioner will not blow cold air.
  11. How much is the repair? It is said that if the repair amount is 50% or more of the vehicle value, it's time to get rid of the vehicle. However, this may not apply, given the brand and mileage of your Lexus. So if you plan to keep it for many years, the repair cost on a per year basis may be relatively little.
  12. Check out my reply to your other post about the coil packs. I'd stay away from Chinese packs. I learned this the hard way with oxygen sensors.
  13. MIL stands for Malfunction Indicator Lamp. The tech may be saying that the OBD II connection is not being established. This can sometimes happen because the connector itself is very infrequently plugged into a scan gauge connector. Sometimes plugging and unplugging a few times will re-establish a good connection. I've seen this happen on a 2004 Honda Civic. I had replaced the upstream oxygen sensor and had to plug and unplug my scanner a few times before making a connection that would allow me to reset the check engine light.
