Lexus LS 2007+ :: No Interior Heat At Idle - Low Coolant In 2008 LS460L?
My 2008 LS460L blows cold air on cold days/nights when the engine is idling. Raising the RPM to about 1500 causes heat to start to flow out of the air ducts. I also hear a gurgling sound behind the dash when accelerating normally from idle. The water pump was replaced by Lexus in late April 2014.
I have checked the coolant reservoir (engine cold) and found it to be slightly below the "LOW" coolant level mark (not empty). It would seem that since the feed from the coolant reservoir is on the bottom of the reservoir, as long as there is some coolant in the reservoir, the rest of the system should be full.
All things considered, are the two issues (no heat & gurgling sound) more likely to be caused by low coolant in the system, the relatively new water pump, or something else? BTW, what is the proper method to top off the coolant in a 2008 LS460L? Are there any special bleed ports for eliminating air pockets?
Prius (Gen 2) :: 2007 - No Heat At Idle?
I have an 07 prius with 105k miles. It had no warning lights on and drives great with 1 exception. The heat gets cold at idle, it works great as soon as i drive or if the ICE starts to charge the battery. I believe the problem was the ICE not coming on to heat it back up, it would only come on if the battery drops not if the air temp drops.
Then my mechanic replaced the pump on the coolant heat storage tank and it made no difference so he put the old one back on. However since then the ICE will occasionally kick on for heat even if the battery is charged (like it should be) but not frequently enough and sometimes not at all.

I have a 09 santa fe and it just started doing this. when we start it and let it warm up it will get the normal temp and will blow hot air but when we start to drive the thermostat goes back down to cold and it will blow cold air. I have had a problem similar to this before and taken it back to the dealership and they replace the same thing over and over. but this time its not fixing itself and it is staying like this. usually it will fix itself.

I was driving down the PA turnpike and heard rear-end noise. I pulled over and this piece was hanging down on the right side in front of the rear tire and at the back edge of the rear door, right where the muffler is. I did a search and found this to be a common problem with the 330s but did not see anything on the 350s. I drove another 500 miles to the beach and then back home without any noticeable affects, but not that I looked underneath.

I was driving home today and noticed a loud fan squeal when I had the heat on. It is a constant squeal and gets louder as I increase the fan speed. It went away if I turned the fan system off. My drive was about 20 minutes and it squealed the entire time. I thought maybe it would go away as the car warmed up but it didn't. 2009 ES 350...

What is the service manual spec for the idle rpm on a 2012 LS (after warm up)? From my scan tool the idle in neutral is 720-730 rpm and in drive it's 780-800. Yes, lower in neutral. I find the car wants to creep forward against the brakes when stopped. The dealer says nothing wrong but has not given me what the idle specs are. Additionally, is the idle adjustable, if so how?
View 3 RepliesLexus LS 2007+ :: Installed New Battery, Car Idle At Around 400 - 450 Rpm
My car battery was bad and took it to get it exchanged for a new one. Car was without the battery for probably around 6 hours. Came home and installed the new battery and car fired right up but I noticed that it idles at around 400-450 rpm. This is with the ac on or off. AC does not increase the RPM any. But I also noticed that at this RPM, the AC doesnt blow any cold air. As soon as I barely press the throttle and it gets to where it used to idle prior (600-700) the AC blows cold again. The car has never idled this low prior. I took the battery out for around 2 minutes and still the same thing. Ive also read about leaving it disconnected for 30-60 min and see if it works.

I have been noticing that the idle in my car while stopped at a light will sometimes drop to 500 rpm. This makes the car feel shaky at idle.

I have an '09 LS 460 AWD and there is a very unlike Lexus knocking sound at idle to maybe up to 20mph. best way I can describe is to imagine a diesel engine at idle, and dilute it substantially. subtle but clearly there. i read here in CL that could be due to valves or such, but dealer insists it is because of the intentionally designed "oversized fuel pump and fuel injector" and completely normal.

View 2 RepliesLexus LS 2007+ :: LS460 Shakes At Idle After Oil Change
I just recently upgraded to a 2007 LS460 from a 2001 GS300 (rear-ended and totalled in an accident). Anyway, I have it for almost a month now, just took it to Firestone Auto Care for a full synthetic oil change for the very first time. I also purchased the life-time alignment and rotated the tires. Last night when I put it in Park, it started to shake pretty badly. I took it to them this morning, but it didn't reproduce the obvious shake so they said bring it back if I feel it again. What could have caused this? The oil change? The alignment? Or could it possibly be the tire rotation? I also notice that the ride is not as smooth and quiet anymore when I'm driving. I can hear the engine bay swirling about, is this normal? I swear I didn't hear that before. Also, my front passenger seat seems to vibrate more than my driver seat.
