Prius (Gen 3) :: 2010 - Engine Coolant And Oil Loss
Apr 27, 2016
We have a 2010 Prius with ~120k miles and a supposed oil leak; about half a quart for the last 500 miles. Ongoing for some unknown period of time. I haven't seen any oil on the ground for the past week. Furthermore, the engine coolant is very low. The dealer believes the "seepage" is due to head gasket, which would cost $2400 to repair.
This isn't my car (my gen 2 runs great), but it reminds me of my beloved 1996 Subaru which had to be let go because of an expensive head gasket and emissions failure. We expected the Toyota engine to last much longer. So far, the Prius hasn't thrown any check engine lights. Is this unusual? Any signs I can look for that might confirm the head gasket leak or suggest a less expensive diagnosis?

I was driving my 2010 Prius on the Highway (less than 2 miles) and the engine check light came on.... shortly after the ! (triangle with exclamation light came on and then started flashing). I exited the highway and was going back home. On the way home, I noticed a decrease in acceleration and then a message 'Hybrid...'
I was able to coast into an apartment complex and then got a ride home.
After about a couple of hours, I went back to the Apartment Complex. I reviewed the manual and one of the options was to check the gas cap. I filled the tank up last weekend and haven't driven it since today.

A demonstration of how the Airlift tool spares you from the hassle of burping the system and attaching a hose to the top air vent on the engine. Done on a 2010 Prius but it applies across the board.

As a Prius driver, I have driven my 2012 Prius more than 110,000 miles. I love the car and have a suggestion on improvement - Create new software to allow the driver to monitor engine coolant temperature and RPM from either the dash display or touch screen display.
I like knowing if my car engine is up to temperature before punching it on the freeway ramp or about to overheat before an idiot light goes on.

I have an 03 Explorer with the 4.0 engine. There is a strong smell of coolant and the reservoir does go down slightly once a week or so. There is No Leak whatsoever that I see, I have checked under the hood, under the vehicle, under the dash, everywhere...nothing. Where is the coolant going? This seems to be a common problem, I work at a quick lube and almost all of these explorers are low on coolant when they come in.

I am getting a P1150 code on a 06 Prius (240k). Red Triangle and temp light come on after about 15min of driving (no heat). I have taken it to the dealer. They said the Coolant control valve (stuck) and waterpump (leaking) needed replacing. I replaced both of these myself along with the temp sensor and radiator cap, but the problem persisted.
Coolant is also shooting out of the overflow hose in the reservoir tank when car warms up. I just took it to a different shop yesterday because I was assuming I could not get all of the air bled out of my system. They charged me $200 and said there was quite a bit of air in the system. The first thing I did when starting my Prius was to check the heat, no heat. I drove it home and immediately noticed there was yet again coolant spitting out of the overflow tube. I didn't want to believe this was happening again. I drove it to work this morning (15min drive) and the red triangle and temp light came back on.
I now have been driving it with the radiator cap loose so the pressure does not build up and spit the coolant out. This works for short drives, but I've noticed my coolant is disappearing quickly. No visible coolant on the ground or anywhere in the engine bay.

I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

I am trying to figure out the problem with my 2002 ford 7.3 Engine.
[URL] ....
It has a lost of engine coolant. The oil is 100% clean with no signs of Coolant. No chocolate milk effect. Also it makes a Odd thumping noise at idle. I think it is coming from the Exhaust Manifold.

So I have a 2003 6.0 king ranch w/ 164k on it.. EGR delete, high pressure oil pump, coolant filter and SCT tuning. A couple months back I had a coolant flush done. After about a week the coolant tank was empty.. Engine heated up due to loss of coolant.. I flushed system again and put ford gold coolant back into the tank. (5 gallons). A couple days later and coolant was very low and engine heated up?? There are no signs of leaks anywhere...Added water and it cooled back down. I'm lost. EGR is deleted but no studs done.....

I drove for a couple days last week and got 60+ mpg (city, well known commute, amenable for pulse&glide). I rotated tires (or rather wheels) this weekend with unchanged tire pressure (~44psi). Today I only got 50 mpg on the very same commute. Is this just a coincident?

So I got my 2012 Prius started worked for a while, then loss of power and got this code P0A0F. A big black cloud also came out of the exhaust. What it means?
Just changed the oil, there was way too much of it, it also smelts like petrol and now I'm going to get new spark plugs as they are in very bad condition and are wet.

Really scary, had my son in the car. Dash read "Check hybrid system". Reading some posts make me think that it may just be the 12V. Had it towed to my house.

Just letting Gen III drivers know that using an OBDII splitter and two gauges can sometimes cause a loss of regen braking and traction assist accompanied by various yellow lights on the dash. It can be restored by switching the vehicle off, unplug the OBDII splitter and restarting the car. This has happened to me on three seperate occasions.

Having issues with a 2014 shutting down. Was at a stop light the other day and car completely lost power and shut down. When this happened oil, engine, and battery light came on. Once I parked car and turned off, it restarted. The dealership acted like I had no idea what I was talking about and would like to have some information when I take it back to have this problem corrected the car is not even 2 years old and has 30,000 miles on it.

With a cold engine in my 2010 Forester (29,000 miles), the coolant level has dropped from "full" to "low" in the overflow reservoir over the last 8 months or so. The level was down at that time (8 mos. back) and I topped it off. There is no obvious coolant puddle on the driveway. There is a gurgling sound at tailpipes and the exhaust is very wet. I'm worried there is a cooling system leak into the engine. Overall I have not been happy with the service dept. at my dealer (bought the car used from him) and wondering if this is the type of diagnosis and repair that an independent shop could handle.

I'd like to upgrade the head unit to something which sounds a little better and offers better A2DP streaming (the Australian Prius I-Tech doesn't offer stock Bluetooth streaming and the GROM Audio unit I am currently using to achieve this is temperamental). Everything I read suggests that you loose IPA if you do this upgrade, and while I know most people probably won't miss the feature, I personally find it very useful.

My 2010 with 130,000 miles has no heat. I had it flushed at the dealer and recall work done last June as part of the maintenance sched and did not try to use the heat until a few weeks ago. I have taken it to the dealer twice. They have in order bled the coolant system, replaced the coolant and then changed the thermostat at the second visit. The catch is that each time they have done this the heat returns and by the next day or so the heat is gone--It has not been very cold yet so we have not needed to use the heat every day. I am wondering if the system is hard to bleed?

My 2011 is at 45k miles now and I've just noticed that my radiator coolant is just under the 'low' mark and my inverter coolant is on the 'low' line. I've had all regular maintenance done, never done any of it myself just because I'm not confident enough in myself to think I won't mess something up. Should I be concerned about having 'low' coolant levels?

Wrecked my 2005 and bought 2006 with 65,000k. Dealer had just changed oil and it is well above last dimple. Dealers have been quoted as saying no harm to engine by overfilling' At first I started out at 51 mpg and after first trip or two it is down to c.47mpg. Will overfill cause loss of fuel...

I'm driving to work this morning and a bunch of warning lights came on. I was going uphill and the car wouldnt accelerate, the engine was revving up and my presses on the gas pedal didnt seem to be doing anything. I had to pull over a couple of times after shutting the car off and letting it cool down. Each time the car would eventually display the loss of power (would not accelerate, and engine seemed to be revving high with no input felt from gas pedal). Shutting off car and turning back on would cause this to go away.

I have a 2009 Prius with about 72k miles on it. Today, after about 45 minutes of highway driving, these lights all came on: master warning, the "check" indicator, VSC, the circle brake indicator, and the hybrid system warning on the multifunctional display.
