Lexus GX 2004-09 :: Coolant Level Seems To Be Going Down
Apr 20, 2014
I've been noticing my coolant level seems to be going down. The last two times I had it in the shop they reported a low level and refilled it. Followed by today I noticed it's near empty on the reservoir. It's disappearing but where it's going. No drip marks underneath anywhere on the driveway or the car. No pink sludge on the bottom of the radiator. No pinkish hue or any indication it's getting into the engine oil on the dip stick... I'm at a loss here.

My friend bartered for a '99 F250, 2wd/auto, 4 door, 7.3, 258k miles.
It had reportedly sat for one year, though the expired registration sticker and other things point to it sitting for two.
It ran low on oil, sputtered and died. Oil in the degas tank. Filled to oil to mid way on the hatch marks on the dip stick.
I drove it 25 miles to my house, and the oil level is not reading on the dip stick.
The sludgy fluid level in the degas tank is unchanged. Where is the fluid going?
I will refill the oil to see just how much it lost in the 25 miles if it important to someone, but I prefer to not waste the oil.
My first plan is to remove, inspect and replace the oil cooler o-rings. Even though the dealership charged him for this, I don't trust that they did it right. I think it is the easiest and mostly likely place for oil getting into the coolant.
It does have a really long crank before there is enough low pressure oil for it to start. At the moment I think this is a separate issue.
The dealership also charged him for a replacement injector. No idea if they replaced the cup or not.

I've got a 07 LS460 with 95,000 on the ODO and took it in for a harsh ride. The tech called back and said the upper and lower control arm bushings are bad along with a water pump leak.
If the water pump is leaking, shouldn't I have known? I haven't had any low coolant issues, smells or fluid on the ground.
I'm covered by an extended service plan, but would like to have known (otherwise I could have gone bust!)

Coolant level message on my 2004 Ion won't go away. I have pulled the overflow tank and cleaned and flushed it. Checked the sensor with my multimeter for continuity, checked fine. Checked and remade wiring connections to the sensor. I thought maybe the float material was the same as would be in an hydrometer so it would only float in the correct mixture/protection level of coolant. Flushed and filled the system with 50/50 mixture of Dexcool. That theory was incorrect. The only thing I've seen so far that makes sense is a "software issue" that was mentioned in another discussion I read.

The last week or so, the coolant level low light has been coming on in my 04 Touareg V6, and I've noticed that it is leaking underneath the car. I've been keeping a close eye on the level, and filling it back up until I could get it into the dealer. They can't get me in until the 24th, so when I was under it last night changing the oil I checked it out.
It is dripping from a round plastic piece on the firewall with a square "knob" on it. This "knob" has what looks like a cross indented into it. It was dripping slowly while the car was on, and continues for a few minutes after it's been turned off. I originally thought it was the a/c condensation dripping off, but it's definitely antifreeze.
I fear that it's the heater core and that it is leaking from the inside, but I could just be paranoid. It should still be under warranty (34,000 miles).

Just noticed my level is about an inch below the full mark, it was fine at the last oil change, no leaks that I can see....nothing on the ground.

On Sunday I'm driving to the store my LOW COOLANT light goes on. So I buy some coolant. I get home let the car cool off and check my radiator, it is full. My coolant recovery tank is also at the proper level.
Been three days already checked levels again and I'm not losing any coolant.
What the car is NOT doing:
1. Not losing fluid
2. Not running hot
I'm thinking coolant level sensor?

I noticed yesterday while driving the RX (not my daily driver) that when I turned on the A/C to bi-level (chest & feet) it only blew cold air at the chest level while at the feet level it was warm air. If I remember correctly from the past that the feet got cold too so I tried it with the vents only at the feet, still warm air. I even checked to make sure that I didn't have it on bi-level with defroster in use.

The AC on our '04 RX330 has started acting up. Refrigerant level is fine. When the system works it's ice cold. It'll run more often than not, but occasionally the AC compressor just won't kick on. I searched the forum and found issues in other toyotas and lexus models with the magnetic clutch relay but for the life of me I can't find where that is on the RX. I also saw reference to an AC "servo" in another thread. What controls the AC compressor and what to check?

I have a 2006 RX 330 with 116,000 miles. I noticed that i had a leak and the power steering oil level was low. I went under the car and looks like the power steering hose is leaking. The dealer wants $352 for hose and $325 for labor. I called auto parts stores and they say its a dealer item only. Someone told me I could have a hose company rebuild it for a lot less.

I started to notice a slight whine when I turn the wheel. My fluid is at low but it's pretty dark and I'm not sure if it was ever changed or when. I have 100k miles. What fluid should I use?

Have a small coolant leak. The level is dropping and I can smell it but I cant find it. The radiator was new at 100K miles and the heater core is bypassed. No evidence on or near the hoses, water pump or radiator. Getting ready to replace all the hoses because they are overdue but I would like to find the leak(s) first.

Level in the tank going down? I don't appear to have any leaks but it's now down to the "Min" level cold.

My Touareg has 9400 miles and yesterday I checked the coolant level when cold. Inside the reservoir there is an awkward yellow cylinder with the max and low words. The manual is not very detailed about where the level should be like the oil, or at least show a picture. I noticed that my coolant is right underneath the letters LOW for the low mark. I would take it that I need to add, but need to confirm whether or not that is an OK level. Could LOW be the translation by the Germans for the cold mark? My American made GMC Envoy has a clear reservoir with precise max-cold-low marks so you can actually safely see the level even when hot and be sure about it. I ask this because today I had the 10000miles service done and the tech said the level is fine.

My coolant level sensor is bad. How do I replace it? I understand that there is a retaining metal wire holding it on. How do I get that wire off?

At the end of last winter, I got the warning flash that my coolant level was low. So I topped up (about a pint or more)About 3 weeks later I had to go through the same scenario !! but then it started to get hot outside and my air conditioner mode took over and lo and behold - no more coolant loss.!!?? Now that winter and cold weather is back - so is my leak!!
So I run off to the local dealer and they get the car up. And drop the belly pan with the engine running and the heat cranked up. the mechanic said he found a dripping hose coming from UNDER the intake manifold.
The engine is a 2002 2.8 v6....

My coolant level keeps dropping really low underhood and the light comes on on the dash, but I went and bought coolant, opened the hood, and the level was back to normal. Where is it all going? Should I add any when it's low if it's coming back? This just seems weird.

When I got the STOP check coolant level message on my 2002 Passat glx. I pulled over as soon as I could and then I began to over heat. The coolant level was good, actually it was a little high. The check engine light also was blinking. I replaced my water pump about 70K miles ago.

So my car is about a year old with 21,000 miles and I just took a look at the coolant level and it's like halfway gone already? I've never seen a leak anywhere so is this normal?

95 caprice 4.3L V8 150,000 miles. I smell coolant every time i drive the car (everyday). Drives fine, doesn't overheat. Smell is not inside the car but when I get out and stronger as I walk towards front of vehicle or stick my nose to the grill. Low coolant light came on about 2,000 miles ago. i filled to proper level in the coolant tank and since then only has lost an inch or so. no leaks on the ground but distinct coolant smell every time. Anything to worry about?
