2008 Highlander - super slow coolant leak. Dealer can't find it via pressure test. Never trips sensor, but after 6 months or so, the heater doesn't work well unless turning to the left. Has happened since new, but now Just out of warranty. Dealer has recorded two pressure tests and leak, but I'm wondering what to do.
View 13 RepliesI have a 2006 F-150 XL with the 4.2 V6, auto that has a slow coolant leak that I cannot find.
I bought the truck this spring, 190K, drives good, but it leaks coolant. I have added probably 3 gallons of water this summer, this does not bode well for winter.
I can't see any wet spots or steam, but do smell anti-freeze occasionally from outside the cab.
I don't really want to try easter-egging the repair (replacing things that might fix it).
How to find the leak? Or should I just use some form of stop leak.
My '05 Highlander transmission seems to be geared wrong. When I slow down the car seems to slip into a higher gear and speed up. It is worse when the air conditioning is on.
View 30 RepliesI have a 2005 Toyota Highlander. Ever since I got 4 new tires (~1 year ago), my low pressure light goes on about once every 6 weeks. Each time, there is at least one tire that's dropped about 2 lbs below recommended psi. Had it to the dealer (where I purchased the tires) and they told me there's no leak in any of the tires; that the low psi is because of fluctuation in the weather temps and subsequent fluctuation in tire pressure. I've never had this issue on any other car before. Are they pulling my chain b/c they don't want to replace bad tires or is this a legit reason?
View 10 RepliesI proudly purchased my new 2015 Highlander AWD XLT last year and brought it in for scheduled maintenance last month for an oil change and tire rotation. With 9,000 miles, I was told there was a fluid leak at the crank shaft and I would have to leave the car. 8 days later the car was ready after they lifted the engine and replaced every gasket on the engine block. I was given a loaner during this period.
One month later the 'check engine' light goes on and the car is flashing 'check AWD' 'TRAC off' . The service rep says I should not drive the car and have it towed into the shop. It took two days to get my car in and the Service Rep doesn't offer a loaner because he says the car is still drivable?
I went from Honda to owning my first Toyota and it's off to a really bad start.
I just bought an 2008 Highlander Base 2WD yesterday and have noticed a vibration while driving during certain instances. Unfortunately it is not constant and I haven't been able to make it happen on purpose. When it does happen, it occurs a second or two after I accelerate and take my foot off the pedal (when I'm not pushing the gas or slowing down). It's like the car is deciding which gear to be in...the whole thing just vibrates for 2-3 seconds.
View 28 RepliesJust purchased a used 2008 HH - about 85000 miles. Seems to work perfectly except there is a very loud hum that sounds that it is coming from the rear. Starts to be noticeable at 30 MPH and gets louder up to about 55, and then isn't as noticeable, perhaps due to normal road noise.
View 2 RepliesWhen I put my 2008 Highlander in reverse and put on the brakes, it makes a very loud and obvious clicking noise. What this might be? I'm very concerned.
View 1 RepliesI'm driving a 2008 Highlander, but this question applies to almost any car, I think. On a couple of occasions the Highlander has lost power, and I've lost braking and steering ability. Each time this happened I was going at slow speeds and was able to stop without a nasty problem then restart the car. But what if this happens and I really need to brake? Three related questions:
(a) Are power brakes going to stop the Highlander even when it has lost power?
(b) If not, will the parking/emergency brake be useful?
(c) If the answers to (a) and (b) are "No", what should I do?
Of course, I'd love to know why Highlander lost power, but my Toyota dealer was not able to replicate the problem, even after driving the SUV 100+ miles (the two occasions it happened to me were separated by about 5000 miles of driving).
Van has 144k miles on it. It's been well maintained (see my other posts). I have had it since new (7 miles). The LIM was done preventively at about 75k miles (5 years ago).
Two to three years ago it started using/leaking etc coolant at a very slow rate. I would estimate somewhere in the 8-10 fl oz per 3-4 month range. As time has gone on it has been progressively using more. Now it is about 12-14 fl oz in about a month or 6 weeks. My "low coolant" indicator came on the other night. It had been a while since I added any coolant mix. 3-4 months anyway. It took about 1/2 gallon (US). There has been no "real" visible leak,up to now. I noticed yesterday when I was under it doing an oil change, that there was a "film" on the bottom of the trans pan. I followed the trail as best I could and it led me to the rear of the engine near the drivers front wheel. It was a small drop of coolant. (I tasted it). Don't try this at home... From the top of the engine looking in, I followed the upper radiator hose to the thermostat housing "pipe". It is very difficult to see in there. I took a few pix. [URL] ....
It looks like there is a little pool of coolant sitting near or under the thermostat housing that pools on top of where the transaxle bell housing meets the engine block. It's very hard to to see in the pix. Some of what looks to be damp, is actually shadow. This pool I believe runs down the back of the engine/trans, and then is blown on top the trans pan and undercarriage.
The van runs great, I want to keep it for the next 9 years. There is no coolant in the oil, or oil in the coolant. Unless the fix is fairly easy, the leak is still small enough that I am not going to bother with it until it becomes a large leak. The car runs cool even in the hot summer pulling a load. The only issue is the leak and that I have to add coolant every once in a while.
I'm trying to troubleshoot a leak on my 08' F250 with a 6.4 powerstroke. It's been dripping coolant when cold pretty aggressively. Once the truck heats up, the coolant leak seems to mostly go away.
Here's a picture of the drip, it's marked by a dart, so you can see the location from the top (second pic). The radiator house connection around the engine seems dry.

What's hidden here that could be causing the leak?
My wife has a 2006 Touareg V6.
Noticed a coolant leak a week ago, refilled with coolant, and as of today the coolant warning has not come back, so whatever it is must be a very slow leak. Today I took the opportunity with the unseasonable warmth in Chicagoland to investigate.
Got the T-reg up on jacks and belly pan removed, ran the engine while inspecting the bay, didn't see anything.
After I shut the engine off, however, I noticed a small but somewhat steady dripping coming from roughly the middle of the front of the engine block.
Pulled the plastic cover off one of the pulleys, part # reads: 022 121 341. I couldn't find a match anywhere online, but I got tons of results for 022 121 011, which is the water pump.
My son has a 2007 sonata v6, daughter has one too. Both have about 130K miles, and both developed slow coolant drip leaks. I took off both hoses on both cars, cleaned the crud from the housings and replaced with new hoses and clamps. Problems solved in daughter's car, not so in sons car. I note that it looks like the area below the thermostat housing is wet - and thought that was from the crud/hose situation. But he is still losing coolant, even more now that its getting colder at night, and I's sure its not the hose connection anymore.
The car will generally NOT leak when hot, only as/when it cools off. I.e. puddle in the morning situation.
Looking at the diagrams, it looks like that "housing" is really a connection to the crossover pipe, heater hoses, other stuff (throttle body heat) and also contains what looks like a temp sensor.
I suppose any of these are possible, but my first thought was either a leaky temp sensor (or possibly loose) or something more serious like a cracked housing, leaking o-ring, gasket etc.
I have a 04" GLI and I was thinking about doing a coolant flush. Looks like I have a slow leak. I was wondering where should I look in order to stop the leak. Put some coolant in about a month ago and now the coolant light is back on. Every morning when I pull out of my driveway there is a small leak under the driver side of my car. Is this an easy fix? If I do decide to do the coolant flush myself what is the recommended coolant replacement?
View 4 RepliesI have a small leak of greenish fluid (appears to be coolant) coming from a silver/aluminum tube that runs the length of my van, just above the left rear transaxle. The leak seems to be in the tube, near a support that keeps the tubing flush against the undercarriage. It is a slow leak, but it is dripping onto the transaxle/transfer case, and is beginning to leave a small puddle on my driveway -- gets a little worse each time I drive. I haven't noticed much loss of coolant in the reservoir, so not sure what this is and how to fix it. I have a photo. I am thinking the tubing might be part of the heating system.
View 4 RepliesOn my 1.8t jetta she is leaking coolant slowly. Just started when it got cold out. It is dripping down the oil pan right down the center. It is falling off the oil drain plug. Was reading that it could be the water pump leaking but then it wouldn't be in the center of the pan. Got it jacked up now so here are some pics.
View 6 RepliesNew truck to me. Truck was advertised with a slow coolant leak. Figured I would trace the leak down and get it repaired no issues. Anyway, working on it this evening I take a close look around the oil filler area and notice the dreaded milkshake color.
I drained the oil out of the truck and the oil actually came out nice and black. Is the headgasket the only area that would cause the oil/coolant mixture? Supposedly the truck has never been overheated.
At any rate, on to find articles on how to pull apart a 4.6L Triton head. I'll see if I'm up to this challenge.
One last issue with my 2000 B3000 3.0L. The leak seems to be on the left (passenger) side of the water pump very near where the bottom radiator hose connects to it. I can't find any loose bolts. It does not leak while driving the truck or soon after. It has to sit for several hours or overnight before it shows up. There are usually 3 or 4 wet spots where it drips from the water pump to the frame to the driveway. It is small enough that I only have to fill up my coolant tank every 1 or 2 months. Could this just be a small gasket leak? It's been happening for about a year or so I think. I replaced the radiator about 2 years ago. I've been expecting it to get worse or bust loose and have been checking it very often. I've never seen one not leak while running like this-has me puzzled.
View 6 RepliesThe a/c compressor is the nearest thing to the medium slow leak. It's up against the left upper side of the oil pan, near the timing belt cover. It appears red on the oil pan but more yellow color on the ground. There are no power steering hoses and the pwr steering pump is further back (and tho a bit wet, it's not leaking) I drove 6-8 mile this morning w no a/c to see if it would still leak...and it did. The power steering resevoir doesn't seem to be going down. Whata ya recon ? bad compressor ?
View 1 RepliesWe had our Timing belt& water pump replaced 5 months ago, due to maintenance book suggestion for our 2006 Toyota Sienna LE, 119,000 miles on her. Now there is a leak in the R & P.
View 2 RepliesA few months ago I developed a slow leak in my drivers front tire. I took it to a local tire shop and they told me small sections of paint on the inner part of the rim that sits on the bead of the tire was corroding and flaking off causing a small air leak. They sanded it down and resealed the paint and it stopped the leak. I asked them if it happened to this rim, could it happen to all of my rims? They couldn't answer that, but now I think I know the answer. 2 of my other wheels now are losing air and I bet it's the same problem. Is there a recall of some kind? Dealer says since my car is out of warranty, they can't do anything.
