Lexus GX 2004-09 :: Coolant Leaked All Over Engine
Aug 4, 2011
So I was going to change the oil today and noticed that there was coolant that leaked all over the engine. I don't know where it came but I washed it off (should have snapped a pic!), so today I will try to drive around a bit and pop the hood again to see where it is coming from.
I'm guessing it leaked from one of the hoses or something. I recently got everything changed (timing belt, water pump, new radiator) about 3k miles ago or so.
I took her offroading earlier in the week two days in a row as well and went through some rough terrain in 90+ degree heat.

I have a 04' RX 330 with 92k. It has small radiator leak. If you are standing in front of the car and look below the fan on the left side of the radiator you can see a small amount of red fluid that has leaked out of the radiator. However, the leak isn't big enough that I ever have to add coolant I just top it off when I get the oil changed. Also it doesn't puddle on the pavement when parked.
The only thing I really notice is that my windows tend fog abit easier now so I assuming the moisture must be making its way into the ventalation somehow. My mechanic said its about a $700 repair. My question should I fix it and is $700 reasonable. Also I've never had the timing belt replaced would it make since do have this done at the same time as the radiator. How long will it take before it becomes a major problem instead of a minor annoyance?

Bought an 07 ES350 from a reputable dealer in March 2013. Had 65k miles when i got it. Had it about 6 wks and 2400 miles and noticed some reddish leaks under the engine. Thought it was trans fluid. I was driving to the dealership to get it fixed - when i noticed the temp guage up near the red zone and the heater (was 39 degrees F out) was blowing cold air. I started to get in the right lane - when all of the lights on the dash lit up - including the "check engine" light. I was able to get over - i think the car actually stalled.
Anyway - after a tow to the dealer - it was the water pump had leaked out "all" of my coolant. At 67k miles having a water pump fail on a Lexus? Did i do permanent damage to the engine?

A bit over a week ago, I posted about a major coolant "spew" in my shed.

Ok so I have an 04 Jetta 2.0 and lately it's been overheating on me. The first time it started overheating was because my radiator was cracked and leaked out all my coolant, I swapped the radiator everything was fine for a while. The second time I started overheating, I saw my primary fan was bad it wasn't spinning at all, I swapped it everything was fine for another while. I also changed the coolant temp sensor, it wasn't bad it's just because the coolant flange was leaking coolant, so I changed it a long with the O-Rings and sensor. I also changed the thermostat just incase that was the problem but it wasn't.
I don't think the fans are turning on by them selves when they have too, but either way the car still overheats when I turn on the fans manually with the A/C. I'm not sure if the coolant is circulating, as the car only begins to overheat when I come to a stop and it idles. I have a feeling it's the water pump but I wanna be sure it is before I change it. What it could be? Things that I should check for that usually go out?

I can see where coolant has leaked out from underneath and come out the sides of the motor beneath the intake gasket.. probably a bad definition but yall probably know what i mean.. i know its a common 3100 motor problem.

I have a 24v Vr6, a couple days ago i spotted some water on my garage floor. I looked in the engine bay and I saw some coolant on this metal can looking piece, it's on the passenger side of the car to the left of the headlight door and a couple inches down. I also looked all the way at the bottom of the engine bay on on the plastic shield there is quite a bit of coolant that has leaked onto there.

Today, the air conditioning stopped working in my 2003 Elantra. Just stopped blowing cold air. Then the engine thermometer kept on climbing. When I pulled over home, I lifted the hood and heard a lot of bubbling and gurgling sounds, and coolant fluid leaked out underneath the car.
What could be the cause of this? When I let the car stay for a while, the AC did kick back on, but only for a few moments and the thermometer kept on climbing again until I turned the car off. The fan is blowing, I can hear it, but it is obviously not cooling the engine off appropriately.

I seem to be leaking coolant, its not coming from the radiator, and all my hoses seem to be okay as well. I removed the airbox, the leak is on the drivers side by the engine. Where this leaking might be coming from?

I was underneath my car yesterday (09 ES 350, 60k miles) doing an oil change and noticed oil and grease caked to the back of each side of the firewall and running down over the axles. I also found a small pool of transmission fluid in the splash pan beneath the transmission fluid cooler. It appears fluid is escaping past the factory "pinch clamps." .
I plan to replace the pinch clamps with the screw/bolt style adjustable ones. My thoughts are that maybe the WS ATF is too viscous for these pinch clamps, or that maybe under heavy load there's too much pressure for them to withstand leaking/seeping. I'm estimating I may have lost up to 1/3 of a quart up to this point, but can't be for sure. I thought it might be engine oil, but found the back of the engine to be dry and my VVTI return line is metal and not leaking. I'll definitely be checking the fluid level soon, although the car is running and shifting fine.

I have an issue with my 2004 GLS 3.5 L w/ 68000 miles. After the SUV warms up for a few minutes I can hear a whine or rattle on the passenger side. I noticed a little power steering fluid leaked out the top of the reservoir (a few little bubbles in the oil). Then reading on the HMA website it says the filter in the reservoir can get clogged and restrict the flow. I took the reservoir off and flushed it out then replaced with new oil.
Unfortunately this did not fix the issue the noise is still there. It's most prevalent when you turn but the noise also picks up a little when you hit the gas. I have checked for hose leaks but cannot find one. My next step is to have the steering pump changed out. While the mechanics in there I am going to have him check the hoses/pulleys really close and look around for another leaks anywhere. Noise is annoying but the steering works fine.

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.

Repaired a coolant leak under the intake? I just repaired the bad o-ring and rtv at the front coolant bypass joint. But, there is still active coolant leaking around the back side of the block and puddling on the garage floor beneath the front of the transmission each night.
So, I'm guessing I need to start removing the intake to hunt this thing down, the top of the block, just under the intake is constantly moist. But I'd like to have a list of seals and parts I'll need to replace before I start.

I was cleaning my engine bay today and noticed there was some coolant in the reservoir tank area, it looks like it's coming out from the cap. The cap does have another hose that isn't connected to anything, just for overflow I guess and I did see dry coolant inside that hose too, so it must be coming out of there and there was some underneath the cap also.
I cleaned it up and warm up the engine and did some revvings and all seems well. No leak whatsoever. Weird. Do they check the coolant at the oil change service? Maybe they overfilled my reservoir tank?

My engine coolant is low, so I just picked some up from toyota to top it off. The bottle says to see the owner's manual for the proper ratio. I don't have mine handy. The best I could find was this PDF posted by Bob. But it doesn't have the ratio. What it should be?

I've been researching how to replace the coolant in my 2004 Camry XLE V6 1mz-fe engine with 55k miles but I need a little more information. It uses the super long life pink coolant. It says service at 100k or 10 years but I feel it is time to replace and or flush the system. I wanted to used distilled water to flush the system but I guess this won't work because the pink stuff is premixed. I would like to drain the entire cooling system and fill again with fresh toyota pink so I can leave it alone for another 5 years.
So my question is, what is the best method to service my cooling system considering I am going to use the same toyota pink coolant. If the proper way is only a drain and flush, I've heard there are two drains on the block in addition to the radiator drain on the v6 1mz-fe. Where are these block drains on the 1mz-fe and will this drain the entire cooling system?

Changed inverter coolant last weekend. Was a snap. Used bleed screw with vinyl tube back into fill tank to bleed off any excess air. Added just as much as I removed. No issues. Took about 15 minutes total. Engine coolant not going so smoothly. I was only able to get 2.9 qts out. Reservoir is still full. Didn't drain that. Started by putting car in inspection mode. Let engine run until it was 180 degrees (using scan tool to read coolant temp). While engine running, turned on heat to get coolant flowing through heater core.
Turned car off. Opened drain plug behind engine. Got about 2 qts out of that. When that was done, radiator level had dropped too. Next, opened up yellow drain plug on back of radiator on drivers side. Got about 2.9 qts out of that.

I'm a little bit low on coolant and I was searching around for it on the Internet and all I need to do is add a tiny bit but I'm not sure which one to go with ? And when I mean a tiny bit I mean it's right under the bottom Fill Line.

I was driving my 2005 RX 330 (138k miles) North on I-75 through Atlanta in rush hour traffic when the car completely died in the left hand lane w/ no shoulder. GDOT stopped six lanes of traffic to push us up and over a couple of hundred yards to a right shoulder. It was determined that due to a coolant leak from the water pump the timing belt malfunctioned and shredded.
I had heard that the water pump should be replaced during the 90k maintenance when the timing belt is changed, but my water pump was not replaced according to my maintenance records. I understand from reading a couple of posts that this isn't always required but that they do check the water pump. Is this correct? And if so should they have noticed that there was a potential problem?

Doing the 48,000 km service yesterday, and when checking everything noticed the engine coolant overflow bottle was almost empty. MAJOR PROBLEM!
There is no sign of leaking, so I presume it evaporated or it was never filled to the full mark from the factory. Man, that level is hard to check. It's dark down there! I may mark the passenger side end of the overflow bottle. Much easier to see the level there.
Coolant loss, presumably from evaporation? This was after 3 years of operation/48,000 km or 30,000 mi.

My 2004 just developed a coolant leak. The past couple times I've moved the car, there's been a small pink puddle under where the engine was. The leak seems to be coming from a weep hole positioned between the two bolts of the lower engine mount. The hole is circled in red in both pics.
