I have a 2007 Toyota Corolla that my kids drive, it has 171k miles. Recently it began overheating and blowing coolant out of the overflow causing it to appear it is leaking due to having to keep adding coolant. The car does not overheat every time but is pretty consistent on overheating. When overheating, the heater starts to blow cold air but if not overheating it blows hot air as normal.
View 14 RepliesI know my car has a leak. Blok check test confirmed. Symptoms:
Car overheats after driving for awhile but only intermittently
Overflow is filled almost to top after driving and has wet sides.
Coolant fails to return to engine.
Here is the interesting part. I removed the lid for over flow and took out the hose and exposed it to air. Then I took off rad cap. Instant suction and collapse of both lower and upper hoses. Why did this occur? Bad rad cap and or/ blockage?
I have an 04 gti 1.8t and last night it started over heating. I pulled over and checked the coolant and the oil but everything looked good. I let it cool down and drove it home. When I popped the hood there was a little steam coming from the coolant overflow tank but I saw no leaking. I decided to vent the pressure off the system and then I got a little drip on the passenger side close to where the inter cooler is. I can't pinpoint the leak though.
View 4 RepliesMy 89 Corolla started overheating when I turn on the AC. If I don't use the AC, the temp. is fine. 2-3 min. after turning on AC, temp. gauge rises and I must turn off AC. My husband, a devout CT listener has some mechanical skills & ck'd it out. He replaced the fan relay, but that didn't fix it. History: the 1st time it happened, the AC was on and blowing cool air, suddenly, the air wasn't cool and I noticed the temp. rising and turned off the AC. I stopped and checked the radiator fluid and it was low, so filled the overflow with coolant. Drove home (30 min.) and it was fine.
A week later, same thing - I'm on the freeway, air is blowing cool, then not and heats up. Ck'd radiator - fluid level is fine. Problem was somewhat intermittent as it wasn't happening 'all the time'. Yesterday, same thing again on the way to see the dentist 40 min. out in mid-afternoon sweltering heat. Had to drive there and back with no AC - quite miserable. Replaced the thermostat not too long ago and the radiator also had to be replaced year before last. I have health issues and really can't handle the heat and fumes and must have AC in this climate. We can't afford to take it to a mechanic. If this car goes, them I'm car-less. It's a great car and keeps on going - 240,000+ miles.
I have a 220k 1994 Corolla with I have come across a couple problems recently. It all started about a week ago when I decided to change my rear brake shoes. The old ones turned out to be all cracked and everything but were generally in pretty good shape in terms of wear. Anyways I put the new shoes in (my first brake job) and tightened up the e brake cable and went for a test drive. I walked away extremely satisfied, the e brake worked perfect which was my main reason for changing the shoes in the first place.
Basically the whole thing worked perfectly until 2 days later. I was driving for about 8 miles when my brake pedal suddenly fell through to the floor (or pretty close) at first I even thought I hit the clutch pedal! anyways after pumping the pedal a few times my pedal feel returned about 70% and after another maybe 10 seconds braking power was lost again until I pumped the pedal. So lucky for me my destination was a 1/4 mile away so I parked and checked the fluid level; it was at the max mark, then I check the wheels/drums and they were REALLY hot.
Also the driver's side drum had a faint smell of brake fluid. Anyways about an hour later I went for a short drive and the brakes worked fine so an hour after that I drove the 8 miles home and about 1/8 of a mile from home same thing happened; brake pedal basically goes almost down to the floor until pumped. My thoughts were that the new shoes were constantly rubbing and the old fluid overheated and caused failure so I flushed the system and put new fluid in and adjusted the shoes "in" with the click adjuster bolt. I had a really hard time getting the drums of to begin with. That and I loosened the e brake cable just in case.
So the next morning I drive about 5 miles without using the brakes pulled over to check that the drums were not heating up anymore (they weren't) so I thought I had fixed it. Well 3 days later (last night) I was experiencing the rear brake stickiness again. Basically when I was just moving from a stop where I had used the e brake to secure the car, I could literally feel that the rear brakes were stopping the car pretty aggressively and sure enough after a few more miles my brake pedal fell through so I poured water on the drums and they started to let off lots of steam, even after like 10 bottles!
So I limped to my friends house at 12:00 AM and jacked my car for a look. Again the drums really didn't want to come off and once we did get them off my friends dad inspected them and could find anything wrong with my installation. The conclusion that we came to was that the auto adjustor for the shoes makes the shoes too tight and they rub. So I am thinking maybe this is cause for the fluid to overheat and boil, causing the pedal to fall through. The pedal fell has gotten much worse since I bled the system 3 days ago so that may be an indicator. Did a test this morning for 5 miles and the drums were just below lukewarm.
I have a 2009 Corolla and the air conditioner is blowing warm....

View 2 RepliesMy 1992 Nissan Primera 2.0 slx is overheating, probably on its last legs. First time this happened the radiator overflow tank seemed low so I topped it up with glycerol and added some leak plugger to the radiator for good measure. The car drove just fine for 20-30km then it happened again. At the same time, and I don't know if this is relevant, the windscreen defroster, which should bleed warm engine air, now only gives cold.
View 3 RepliesI have a 1998 Ford Taurus SE 6cyl 24 valve Duratec with about 135k miles on it. It has started to overheat. It has a closed system with the thermostat on the bottom passenger side. It isn't leaking coolant but it does boil when it heats up and you can hear it whistle/pop around the overflow cap. I have drained the whole system using the petcock valve and have changed out the thermostat (which because of its location requires all the fluid to be changed or you get green rain). So, new thermostat, new coolant, still overheats. The defroster air is blowing cold. It has a belt driven water pump but I haven't touched this. Both electric fans are working.
I don't see anything in the oil. It is still a nice dark color, not milky or anything. I saw no oil in the coolant I drained. When it first starts, there is a few seconds of puffs of white/gray smoke but it is very light and goes away quickly. There is no water running out the tailpipes.
My question is, what is your guess on the cause? I'm at the point with the car, with its age and miles that I'm not willing to dump a lot of extra $$ into it -- so there will be no head gasket change -- but don't want to junk it if its something simple. I do most of my own work on my cars. How can I diagnose it further? Should I just change the water pump and if that doesn't work then what?
My sis has a 09 corolla le and was fine until 4months back. Her STOP fuse #9 would blow. She took it in to toyota, they replace her fuse for her and let her go.. A month later it happen she took it back and they replace it again, so about a week later it happen. Now the Toyota guy tries to check it and but cant find out the problem and tells her that she needs to go see an electrician... he replace for her and gave her extras for the long run... recently until now it was running fine, then it happen again, the #9 fuse blew up yesterday and today!... Her brake lights won't come on when she steps on it and it wont go into drive from park unless she press on that bypass switch.. I know that there could be a shortage somewhere..
View 8 RepliesI took my car to a mechanic after my AC compressor went bad and after he replaced it I noticed that none of my meters on the dash work, the rpm meter is fluttering, the mileage tracker etc have stopped counting, the power steering takes a few seconds to kick in after you start the car. He was able to fix the AC initially but now it's just blowing hot air intermittently and now the car won't start at all. Alternator has just been replaced and we tried to jump the battery to no avail, its a relatively new battery and has never been fully discharged.
View 8 RepliesI've got an 1989 Celica St that as it warms up it pushes water out through the overflow bottle. The car seems to be cooling ok as long as I don't get stuck in traffic. My daily commute is approximately 40 miles and if I keep refilling the radiator the car stays relatively cool. However, if I do not stop and let the car cool off between commuting to and from work the car loses enough coolant that eventually it starts to overheat and I need to pull over and refill the radiator once again. I have replaced the radiator cooling fan already and am going to flush the radiator this afternoon. I am thinking that the head gasket might be leaking and causing my problems. What to try next b4 I tear the head off? BTW the motor is a 2.0 L 16 valve. Hoping I can fix this problem w/o a head gasket.
View 14 RepliesLast week I drove my 2007 Honda Odyssey with about 100k on a 4 hour trek in the cold, and all of the sudden the heat stopped working. The fans were blowing, but warm air was not coming out. It was Christmas eve and nothing I could really do about it, so let it be. Drove another 10 minutes that night with no heat to my destination, and many hours later still Christmas eve I drove another 15 minutes. Heat didn't work, but car operated just fine.
Christmas day, drove the car for about 20 minutes with no heat, and all of the sudden the temperature gauge skyrockets, and the engine light goes on, the car is clearly overheating (could smell smoke from the engine). Let the car cool for the rest of the day, check it and there is no coolant at all. Had a local mechanic check some other things like the thermostat but found nothing, so refilled the coolant, and drove 4 hours again with no problems--heat works and everything. I was expecting to have to stop all the time to refill the coolant, but didn't have to because it never leaked on the entire trip. I took the car to the Honda dealer and they check it and find no leaks and nothing else wrong with the car, and offer no explanation on how the coolant magically disappeared, only confirming that they cleaned coolant which had leaked/spilled all over. The only possible explanation was that I had some work done on the car a few months ago (new belts) and the mechanic I used didn't flush the coolant properly.
I was driving my 2008 Santa Fe last week (before I went on vacation) and noticed the the A/C wasn't coming through quite a cool as usual (almost felt like the vent was on w/ no AC). Then after about 10 minutes of driving I noticed the thermostat on the car get to about the 3/4 line pretty close to the red lines.
Luckily I was home so turned the car off and popped open the hood. I noticed the reservoir tank was empty and there was some coolant that dripped down on the fans & a small pool of coolant on the engine block right under where the oil is poured. (nothing has been dripping under the car)
I added a little coolant to the reservoir tank and the next time I turned it on and let it run for ~10 minutes, it was the same thing.
Anyway, I came back from vacation and opened the hood to try and identify exactly where the leak was, and ran the car for ~30 minutes, with A/C on full blast and the car didn't overheat or leak anywhere. Coolant tank was still full from when I filled it the first time.
What could have caused the leak/overheating in the first place?
I am going to change the coolant in my 2009 corolla 1.8L. The service manual instructions tell me to open the "cylinder block drain cock plug" and I can't find it. The picture in the manual is not very clear, but it points to a spot on the engine just above the throttle body.
View 9 Replies2001 Jeep Cherokee sport ... Just bought this Jeep with 145K miles. Had radiator and all hoses replaced. The overflow tank is boiling over but the engine is not overheating. Safe to drive? What should I be checking for?
View 13 RepliesOver the last few weeks, I'd been smelling something. Today, I realized it must have been coolant. Today, my 225,000 mile, 2.3L 4cyl 5spd 1990 Camry started blowing smoke. When I parked, and gingerly touched the radiator, it was cool -- and empty. When I squeezed the upper hose, it crackled as if very dry. I drove the car about a mile and parked it at home.
When it cooled, I confirmed the radiator is empty -- except for a lot of reddish crud. A hint of the same reddish color on other engine parts MAY be from coolant spraying under the hood, but I'm not sure.
I couldn't tell from spots on the garage floor whether the coolant had leaked out there or not.
How should I proceed from here to address ... a) the leak, and b) any other damage caused by running the car dry?
My son has a Honda Civic where the engine keeps wanting to overheat. There are no fluid leaks, and we replaced the thermostat. It keeps "blowing" the cap on the overflow.
The fan seems to be working fine, so I don't think that is it. Once it warms up, if you squeeze the hose from the top of the radiator, it is not seem to be pushing much water through (water pump??). You cannot see into the radiator (to check for air bubbles), but popping the overflow cap makes me wonder if it the head gasket has blown, and we are getting exhaust into the coolant system.
My '09 2.4L Vibe has started to leak coolant around the coolant temperature sensor. It seems rather odd to me.
Who makes the OEM model? It shows as GM Part 88975489.
Why my coolant overflow tank would be bubbling away whilst the engine is hot? No signs of overheating, not done a compression test yet though.
When the engine is cold, the level in the coolant reservoir is higher than it should be and the radiator was low.
2007 FJ Cruiser, 4WD, 65K Miles. I replaced the 120 AMP Fuse. Starts, everything seems to work, but the 40 AMP Fuse (ABS Motor) is blown. New fuses blow as soon as I place them in. Brakes pedal has little resistance and can barely stop the vehicle at slow speeds.
What will stop the 40 amp ABS fuse from blowing?
