    I have replaced the thermostat and replaced the coolant. I now have determined I only flushed from 1 of 3 flush plugs/valves which was the one at the base of the radiator. There is also one at the oil filter and one on the back of the engine which were not flushed. I replaced about 1.5-2 gallons...

    Dealer says the system is charged, clutch is working, and system is functioning. I hear this ticking noise coming from dash and took this video of the noise from the driver's side footwell looking at the center stack just above the kick panel: Any idea what is wrong? Is it the actuator?

    Noticed a puddle under the front of the van, not where the A/C usually drips. I couldn't see the source, so took it to a shop (Munro Muffler) to see if they could find it. They found a crack just above the lower hose. Took them a couple of days to get a radiator in, so they suggested I leave the...

    I dont know if its me but I always feel that the engine takes more than normal time to get to the operating temp in the cold winter time. I am renting a lots of car for my job and they all get to the normal temps faster. I've tried to minimize the use of the heater especially before then...

    Hi, I was wondering if anybody else has noticed if the air circulation on their Sienna is a bit warmer than the air outside. I'm guessing maybe 5C-10C warmer. It seems to get worse when the car gets warmer and the sun is beating down on the car. Was driving yesterday with outside temperature of...

    I have seen a friend idle up his car for a few minutes every morning to heat up the engine before driving his car. I dont recall any formal guidance for 2006 siennas. Do we need to idle the car before we hit the road?
  12. Problems & Issues
    I have a 2009 Sienna LE with a Manual AC/Heat system. When using just outside air on a cool day, and after the engine heated up, I noticed that the vent air seemed warm (Temp to full cool detent before A/C & Recirculate automatically turn on). A thermometer confirmed that the vent air was 11 deg...

    Hi all, I have been experiencing problems with the driver-side vent blowing warm air when the AC is on and the temperature setting is low or at its lowest. Interestingly enough, the passenger side vent blows ice cold. Have anyone ever experienced this? I have been searching the web and have...

    I am still learning things about my 2000 LE even after two months. Got in the car to leave with the kids to go to the movies this afternoon. It was @95 degrees outside. Turned on the A/C and as I was strapping my 5 year old into the seat, I noticed the left rear vents were warm and the right...
