This video is about the Toyota Prius Gen 3 Temperature Indicators and cooling system overheating. I thought the prius did not have temperature indicators but found out it did, so this video is about how to know if your toyota prius is overheating and understand the basics of its cooling system.
View 2 RepliesI have a 1998 isuzu trooper. it is over heating and there is air being put into the cooling system. there is a lost of fluid but only the same amount each each time and i dnt knw where too. i replaced water pump had radiator serviced and it flowing at the right flow for truck. it still over heated. i tried chemical called blue devil it worked for two days then failed it is freezing cold here and no garage but do have all tools.
View 9 RepliesAlrighty. I have replaced everything dealing with my coolant. New water pump, mishi radiator, pusher fans, thermal switch, temp sensor, t stat, t stat housing coolant pipes, also new gasket and o rings. All new coolant pentofrost sf. Today I went to bleed the cooling system and waited til it did not suck any more coolant down, and we're no signs of air bubbles. Today when I drove it a to Walmart it began to over eat quickly. I pulled over and looked ubder the hood. Coolant was dripping out of my 19-21 pounds moroso cap. And my coolant hoses were rock hard.
Although my top radiator hose was very hot and my bottom was not, but closer to the motor it was. Like if there was a blockage but there isn't in the hose that goes to the block on the bottom of my radiator. Even with the air flow and my fans manually turned on when I first started the car it was steal overheating. On my vehicle there is not a reservoir it has been deleted. I have just my hoses and my radiator that's it. I don't know what can be causing this to happen. Also I ran an air pressure test and my head gasket is not leaking. Any clue what could be going on????
2003 F-150 Supercrew w/4.6 V-8, 2-wheel drive, 219,000 miles and very well maintained. I'm getting an intermittent overheat condition that I can't figure out. Coolant level is good and I just replaced the thermostat. My OBDII app showed it running at a constant 207 degrees (195 thermostat) after the thermostat. Appears to have good pressure at the cap. It ran great for 30 minutes at idle and then did fine for a five mile test drive.
The next day in the morning it overheated within 3 miles of the house (heat was on) and you could smell it. Pulled over and let it sit for 20 minutes and started back up and it stayed constant at 207 all the way to work (11 miles). It sat at work for about 7 hours and ran great all the way home (without heat, with heat, with air cond). Then this morning it did it again, overheating about 3 miles from home. This time I pulled over and shut it off for about three minutes. Turned the key on without starting and the temp was already dropping again. So I started it up and it continued to drop down so I drove to work with no more issues. This afternoon again went home and it never overheated.
I'm expecting it to overheat again in the morning. I'm gonna go live on the OBDII for temps during the drive tomorrow.
I have a 2005 honda civic. About a month ago it started overheating. Drives Ok on the highway but heats up to the H mark almost as soon as I get off the highway. Have replaced the water pump, thermostat, radiator, flushed the system, most hoses, fan, 2 sensors, timing belt, spark plugs and had the head gasket checked 3 times by 2 different shops. Both said it was fine. The mechanic that has done most of the work is baffled. Says he has never seen anything like this and is at a loss as to what to do next. I am supposed to drive this car halfway across the country in a week to meet my husband who is in the air force. Should I just sell this piece of junk!?
View 10 RepliesI borrowed a friends 2000 Excursion with the Triton V10, along with his 3300lb, 28' trailer to tow a car from Ashland, OR to Reno, NV to begin a restoration project. His Excursion has 175,000 miles on it and made the trip down flawlessly, but as they say, "No good deed goes unpunished." When attempting to return last Sunday, had to turn around due to overheating problems. Analysis at a local automotive shop concluded a bad radiator cap. Attempted the return trip Tuesday and the same thing happened (only got farther due to the new cap and ability to hold pressure longer).
Finally got into a Ford dealer and have been informed that the truck has a bad head gasket causing pressure to leak into the cooling system. They suggest replacement of with a remanufactureded engine as opposed to replacing head gaskets, due to the time on the entire engine (who knows what else might be bad?). The vehicle can be driven around town for miles with no problems. But put that heavy load on it and grades and it spews out nearly "all" of the coolant.
Two weeks ago a large, industrial truck dropped a piece of bent steel pipe on the interstate in front of my 2010, 50k miles, Prius and (sadly) I was forced to hit or swerve into rush hour traffic and cause an accident. It tore up a good part of the cooling system and did some body damage. Of course I didn't know this at the time, but it began to overheat, so I pulled off the freeway and had it towed to a body shop. After about ten days, I got my Prius back.
View 13 RepliesMy 2009 has been showing the CEL off and on for a few weeks. Have had it read at auto zone twice, two different codes. Both cooling system related, but not the same. Today I filled the gas tank and it went back off.
Is it possible for the cap to be causing the light, or would the scanners tell that in a code? I just hate to take it to the mechanic when it is running fine and the light is not even staying on.
I heard that you could place a flat screwdriver between the upper radiator hose and the end of radiator. Is this procedure really work?
View 10 RepliesI'm coming up on my 120K service and will be replacing the spark plugs, PCV valve and I wanted to exchange the engine coolant (SLL pink stuff) for the engine. I replaced that stuff on the inverter side when they replaced the heater at a TBS recall.
I have a haynes manual and have searched on prius chat, but just cannot find specific instructions about this. On my '65 Ford mustang, there was a stop cock that I would just open or I would pull the lower radiator hose. To flush I would just pull the thermostat and run water through the system to clean then refill with antifreeze and water. I think that it will take about 6 quarts so I ave 2 gallons of the SLL pink stuff.
I have a 2007 Prius, and bought it used about 4 months ago. I have not had any issues with it until last night. Last night I was driving home and the red triangle with the “ ! “ in the middle and check engine light came on. The car seems to be running fine, but it scared me to see the lights come on...so this morning I called my local Toyota dealership.
NOTE: I recently went to them for an oil change and they informed me that I had three recalls on my vehicle that needed replacing, but I did not get them replaced because I was told it would take 5-6 hrs (which I didn’t have at the time).
Anyway, they told me that it would cost $70 to have the codes read...and that did not include parts that may need replaced... I thought that sounded a little high for just having the codes read so I went to my local Autozone and they gave me this code:

2010 Prius IV - when I have my ac system off and outside air on the system seems to heat the air to whatever the temperature was last set at? This should be a vent condition and air should be coming in from the outside even if the air outside is 50 degrees and the system was set at 70 when it was last on? The system seems to be heating this air. If I turn the system on and reset the temp lower, then turn the system off the air comes out cooler? Why is this?
View 5 RepliesI have a 2010 IV Prius that has been having the following issues starting up / turning off:
On February 4th in the evening: car wouldn't start. Started on 5th try - showed "HYBRID SYSTEM OVERHEAT."
On February 15th in the evening: car wouldn't start. During multiple attempts to start hybrid screen to the right of speedometer flickered / went in and out and was faint. Started on 5-6th try.
On February 16th in the afternoon: car wouldn't start. Hybrid screen to the right of speedometer flickered and went in and out during startup attempts. Eventually car started at 5-6th try - but display to the right of speedometer did not come on at all. Car felt like it was running on engine only.
Took car to Toyota dealership. They had it for 2 weeks and could not figure out what the issue was. Car did not show any error codes. Said they did not experience issues either. Gave me the car back.
On March 3rd, as soon as I got the car back and while still in the dealership parking lot, I pressed the start button with my foot on the brake and only the AC / radio came on. Called over service advisor and when he came tried it the car started up fine.
I was just wondering where the interior temperature sensor of the hvac system is located?

View 1 RepliesToday my a/c stopped working, it just blow normal temperature air not cooling, never had a bad experience with it before, I even use it not on the lowest set up, always on 19 Celsius. It was working fine when i arrived at work, 10 minutes later My boss told me to pick something up and when I turned the a/c on it Never worked.... Is this normal?
View 1 RepliesThis car started overheating while at drive thru and I noticed the cooling fan was not on. The coolant overflow tank was bubbling and the top had come off spilling coolant. dre it home and it runs hot now while driving. I pulled over a couple hours and let it cool off and then added coolant to the radiator directly and drove home with no issue.
Checked coolant level today and it was fine and I drove it a mile and back to the store with no issues. I wanted to ask how I could rig the cooling fan to stay on all the time to see if that is the problem before sinking money into t plus I am not convinced there is a more serious problem especially since it ran hot while driving.
2nd time happening to me: I started my car, backed up and drove few hundred feet before stopping at a traffic light.
While stopping there, I noticed the engine cooling fan was running at max and the temperature was going rapidly up (in less than 10sec the gauge almost hit the red line).
While the gauge was going up I shifted the gear stick to P and the gauge dropped to normal in less than 5sec.
I shifted back to D and the car drove normally ever since.
The temperature gauge in my 2006 S60 2.5 T suddenly stopped working and I noticed that the cooling fan was stuck on relatively cool Michigan weather. In addition I also noticed a 2-3 mpg reduction in average fuel economy and a reduction in overall power. I did a little research and found that the 2006 2.5T models had an ECT recall. Turns out the ECM was telling the engine to operate at overheating conditions,due to a faulty ECT.
Picked up a new Engine Coolant Temperature Sensor (OEM is recommended by most authorities for replacement sensors). I replaced the ECT without even removing the engine cover, it didn't fix the problem at first. Then I pulled the fuse for the ECM, a 5 amp fuse in the box mounted on the drives side fender, and let the ECM reset for a few minutes. Then, had the temp gauge back, and had peak engine performance at operating temperature.
Yesterday, I was waiting inline at a fast food drive-thru and noticed that my A/C was not cooling (it was 100 deg outside). I then put the car in park and revved up the engine and then cool air started to come out of my A/C vents. I did that for 2-3 mins, then noticed that my temperature gauge rose almost all the way to the top (it went right under the red). At that point I took off (out of the drive thru), to get some air flowing into the radiator. Sure enough it temperature doped fast. After looking under the hood. I noticed that one of the two fans to the radiator will not turn on. I'm guessing that's what caused the over heating. I am not sure if I did any damage to the engine though, it did run really hot but not to the red mark but a hair line right under it.
View 5 RepliesI have had some ongoing issues with this car the last 3 years over overheating, I have like clock work been replacing my thermostat in the line, well this time I replaced that danged thing again and the heating was still an issue, (yes oil and coolant filled. ) so I replaced the sensor in the motor and the fan would still not engage . so I pulled the fan and connected direct current to the fan and it did indeed start right up. so its not the fan motor, I hooked a direct current where the ah hell mental block here the plug sensor by the fuse, that was replaced, and yet still no fan engaged.. Here is the rub, If I have the AC on the motor fan will run...
