Prius (2004-09) :: Coolant Leak Appear On Outside Of Transmission
Oct 31, 2014
I have a coolant leak that appears on the outside of the transmission. The Toyota dealer tells me it is an O ring between the transmission and the engine, and this part is not individually replaceable. The dealer says there is a lot of rust in the transmission, which is what caused the problem, and they want $1800 to replace the transmission with a used (125K miles) one.
The Prius is a 2004 model with 100K miles on it.

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.

I just bought my 2006 Toyota Prius about a year ago in 2009. It has been treating me LIKE GOLD !!! up to this point. About a month or two ago, the check engine light came on and stayed on along with a big red triangular warning light. I let it go for about a week hoping that it would just go away.
I brought the vehicle into my local Toyota dealership so they can diagnose it.They told me that they had 3 or 4 different "codes" coming from the machine when getting the signals from the check engine light. All the codes were related to the cooling system. They said that they felt that there was "debris" clogging the pathway for the coolant flow throughout the engine. They had recommended a "coolant flush" for the hybrid side as well as the mechanical side. So I took their advice and I had them perform the coolant flushes.
After leaving the dealership that 1st time, the check engine light came back on the next day. I called the same dealership and explained it to them. They asked me to bring it in again. SO I brought it to them a 2nd time. They diagnosed it again. They told me they came up with 2 of the SAME "codes" and 1 that was different, but ALL the codes were STILL related to the cooling system. They explained to me that something was preventing the clear flow of coolant throughout the engine. And since the thermostat was the only major obstacle, they recommended that I replace it. Well, I did. And after I left the dealership that 2nd time, I was praying that this was the last of my Prius issues! The check engine light came back on the next day.

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.

My original intention was to replace the engine oil in the car. I was in a hurry(yes....I know) I could not find the oil drain plug. I did find a large bolt which turned out to be a drain plug for the inverter coolant instead. The instant the fluid drained from the car, I knew it was not engine oil. I did not know the drained fluid was inverter coolant. It had the color of a transmission fluid but significantly less viscous.

I've never had a leak before in my anniversary and now all of a sudden I have a coolant leak. Once I start the car and run it for a short time and shut it off I lose a few ounces of coolant. I inspected under the hood and the coolant seems to be leaking onto my tranny. I am unsure where exactly it is coming from.

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.

My 2001 Prius with 134k miles has been running great but leaves a small amount of coolant on the ground after parking. I've had to add approximately 8 ounces per 100 miles.

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?

My 04' GTI, 24v VR6, all stock, @ 107,000. I had a coolant leak from the t-stat housing. I installed all new housing, seals, and C-Pipe from GruvenParts. Already had a green CT sensor installed and the kit I got didn't come with one, so I didn't change it. Found out the leak was from the t-stat housing o-ring didn't fit the old housing. The new one fits perfect. I put coolant on the seals and burped it. Doesn't leak a drop. But still overheating, all the hoses have pressure and are hot, so no blockage....I noticed the fans were not coming on at all. The fans used to engage every other minute and run for 15 secs on high ONLY. Longer times, if not constantly w/ A/C on. I was wondering how to test the fans, sender, and/or fan control module to see which one of them isn't working. And which pinouts are what?

I 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.

Is it possible to use so much coolant system stop leak that you could clog the transmission cooling system?The fluid is burned and seems like I am having problems with gear shifting and power from the transmission. 2003 Olds Silhouette...

2001 Prius with 190K Km (119K mi) on it.
Some background on the car: An inverter replacement when it was less than one year old, the Big-Hand issue, the engine ECU (I think) replaced just after warranty expired, resealing of traction battery terminals... And last month the front brake pads (original) had to be replaced because the driver side inner pad fell off while braking on the highway. lol. The problem was probably due to the inner pads being jammed and received excessive wears. Also, on at least two occasions, the engine ran with extremely low level of oil, or none at all (to the point where the engine sounded different and occasionally shuddered). I don't know what caused the oil level to drop, but ever since then, the engine seems to be going through the entire reservoir of synthetic oil advertised to last 25000 Km in just 5000 Km (~3200 mi). Not sure if the engine is eating up the oil or the car is leaking oil (there is no oil stain where the car is normally parked).
Problem: When the car was brought in for tire replacements last week, the tech noted that "Head gasket leak. Also leaking from tranny cover. Could be crack seal" with an estimate cost to fix the issue at several thousand dollars, which has been vetted by a family member who is a heavy mechanic. I have attached the report for reference.

I'm a new owner of a used 2008 Prius. Car only has 67K miles and other than the leak, appears to be in good shape.
I noticed the coolant was low in both reservoirs, filled it up (with the proper SLLC), but a day or so later the check engine light came on. Took it to mechanic (dealer is 2 hours away), he read and cleared the codes, then found the leak. Appears to be leaking where the lower hose attaches to the pump, so not sure if it's the pump or the hose that's the problem. I've also noticed that the pump seems a bit noisy for a few minutes after shutting off the car (of course, I'm new to the Prius so not totally sure what "normal" sounds like).

I've got an '04 1.8t jetta with 158k on the clock. Recently noticed I have a coolant leak on the passenger side of the car. Started the car in my driveway and looked for drips and found coolant collecting in the front valence right underneath the intercooler. Took a look from the top and noticed the hose going into the bottom of the part shown in the picture is leaking like a sieve. It's the metal canister-type thing on the passenger side right next to the radiator. What part this is? And where I can get a new hose that connects to the bottom of it?

Changing my oil today, been awhile since I had the hood open for an inspection a year maybe about 5 - 6K miles
It's been about 2 years since the prior owner had it in for a service, I recall they had it in right before we purchased it in August 2008
I live in Miami Beach where it's HOT
I noticed the inverter coolant level is no longer at full It's hard to see where it's at, actually
It's not below low, and it seems to be at least up to the bottom of the double seam that wraps around the tank, but I can't see where it levels off behind the seam
Should I be concerned enough to take it in to the dealer and pay them to hunt around until they find a small leak, or is it normal to lose a small amount of coolant over the course of a couple years
Should I just buy their high priced Toyota Super Long Life Coolant and top off the extra 1/8-1/4" or so until it's at FULL?

Or at least, I assume it's the Hybrid Drive. The service campaign to replace the inverter pump was completed on Friday. The Coolant Control Valve was replaced today (I TOLD THEM to have that part for the service on Friday, but I digress). I'm now seeing red fluid dripping under the car. It appears something wasn't tightened down correctly.
Given that it appears to be a slow leak, and I need to get the car back to the dealer to fix it (40 mile trip), should I make them tow it back at their expense, or is it safe to drive it that far? I have NO replacement fluid to add in the meantime, and if I recall correctly, that's a dealer only part.

The coolant is leaking from the gasket that is on the front of the engine. My repair guy suggested that I also do the timing belt at the same time. Do I have any other options? The Honda has 217,000 miles on it.

I have coolant leaking from the bottom of this hose on my brothers car. I am not very familiar with the BEW's as I drive an ALH. Just looking for info about part number or name on this hose so I can get a new one. Has a part number MH3364 on it but that is not working anywhere.

So went to move my truck after getting 30 inches of snow last night, noticed yellow underneath my truck, backed up the truck and then noticed it was also dripping down off of the back of the muffler???? Moved my truck about 25 feet away and let it idol for 20 minutes as a plow moved the snow, kept checking but no more leak? Just checked again, and there is plain old water dripping from under the truck where the snow is melting but still no more yellow. Can coolant leak and rundown down the length of the exhaust and then collect and drip? 04 f150 fx4 5.4

I have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?
