Toyota - Corolla :: 2007 - Overheating And Blowing Coolant Out Of Overflow
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.

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.

2001 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?

Doing the 48,000 km service yesterday, and when checking everything noticed the engine coolant overflow bottle was almost empty. MAJOR PROBLEM!
There is no sign of leaking, so I presume it evaporated or it was never filled to the full mark from the factory. Man, that level is hard to check. It's dark down there! I may mark the passenger side end of the overflow bottle. Much easier to see the level there.
Coolant loss, presumably from evaporation? This was after 3 years of operation/48,000 km or 30,000 mi.
Ford - Explorer :: Coolant Level Starts To Rise In Overflow Tank After Rev Up The Engine
I have a 2002 Ford Explorer and I am still trying to figure out why the coolant will overflow in the radiator reserve tank. I put in a new thermostat and a new cap to the overflow tank. When the tank is cold, sat over night, I put in new anti-freeze to the cold coolant line. Then I start up the explorer and let it run for a while. The temp gauge goes up, then drops a tad and cold air comes out of the vents.
After I rev up the engine, I see the coolant level starts to rise in the overflow tank, then it goes to the top and starts to leak out. This takes a while being the thermostat has not kicked in to suck the fluid in. Before this happens, the heater core lines are luke warm. After the tank overflows, the remaining gets sucked into the engine and I get nice warm heat. What causes this. I had the test done to see if the head gasket is bad. The test was negative.
Ford Ranger / B-Series :: 1993 - When Engine Warms Up Coolant Overflow And Spills Out?
1993 ranger, 3.0 V6 203,000 miles. As engine warms up coolant in blown into over flow and spills out. At that point system is low and truck runs hotter than norman, 3/4 way across gage. What would be causing overflow to overfill from engine. Could it be a bad rad. cap? Just replaced head gaskets at 200,000 miles. Truck runs good. No oil in water, no sign of visible leakes other than overflow tank overfilling and loosing coolant.
View 10 RepliesNissan :: Overheating / Radiator Overflow Tank Low
My 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 RepliesFord - Taurus :: Overheating - Whistle / Pop Around The Overflow Cap
I 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?
Celica :: 1989 Overheating And Push Water Out Through Overflow Bottle
I'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 RepliesHonda :: Overheating / Coolant In Engine
I have a small car which has only done 28000 kms and I bought it brand new. I have noticed it has been using more coolant than normal and it has become quite hot at one point. My mechanic went to service it and said it appeared that water was in the engine. (contamination of oil underneath the oil cap). As it is under new car warranty I took it back to the dealership. They said it was due to leaking core plugs and have replaced them. My mechanic said if it was leaking core plugs the coolant would be leaking out onto the ground not into the engine and contaminating the oil. Dealership said this is rubbish. I am confused and don't know who to believe. How do I know if it has been fixed or not and how do I know if it isn't something worse like a cracked head gasket?
View 5 RepliesHeaters Overheating Engine - Coolant System
Had a lot of problems with my Rover streetwise's heaters / overheating engine. Firstly, the heaters were rubbish & took ages to heat up. I took to garage and they pressure washed the coolant system to clear any blockages. This didnt work so they changed the thermostat - this has worked the time it takes to heat up but now when i use the car for the first trip of the day, t as soon as the engine has heated up & the speed hits 50/60 mph, the temp gauge shoots right up to the red zone - so have to reduce speed. The 2nd trip of the day, it seems to be fine - its literally just on first use of the day ie to work.
All oil & coolant looks fine and the head gasket was replaced summer last year.
Prius (2004-09) :: 2008 - ICE Water Pump Failure / Engine Coolant Losing
I bought my 2008 JDM Prius a couple of weeks ago, at 84,500km. After a week, it started losing engine coolant. (Great start! Hope it's not a sign of things to come...) Fortunately, covered by a 3 month Dealer Warranty - hopefully. Yet to make the claim.
Anyway, went to the local Toyota Dealer to get some of the proper Toyota SSL (Super Long Life) Coolant to top it up. Got chatting with the Service Agent about Prius Service and what HSD Adjustments are possible (not many) and showed him my symptoms.
Civic - Honda :: 2001 - Engine Overheating - Coolant Leaking?
I drive a 2001 Honda Civic EX and have over 248,000 miles. Almost at a quarter million! Recently, the engine has been overheating. The coolant has been leaking and the coolant reservoir would becomes full. I've checked out the fan and the fan relay and both seem to be fine. The temperature seems to increase (to redline) during traffic jams and any times of idling. When I blast on the air conditioning, the temperature seems to decrease, but would later increase when the car idles. The temperature also decreases to normal when I sustain my speeds over ~60mph. Also, the temperature will fluctuate from cold to hot to cold. What does this all mean?

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.
Cavalier - Chevrolet :: Overheating When Engine Work Hard And Coolant Leaking
My 1994 chevy cavalier is overheating mainly on hot days and when I work the engine hard. My coolant level hasn't dropped in a long time and the coolant cap is usually dry. I replaced the thermostat and checked the radiator hoses. They seem to be fine. My engine is leaking coolant.

Passat (B5) :: 2000 - Loosing Coolant Through Reservoir Overflow
I have a 2000 passat tdi, over the past months ive noticed that I have been loosing coolant through my coolant reservoir overflow, my car has been running perfectly, my mechanic told me that its likely to be a head gasket problem and he put ceramic sealer in the coolant system, which was a disaster, the coolant pressure became much worse and told he me I needed a new radiator, which he fitted, but there was no improvement, whilst my mechanic was working on the car he noticed that when my car was running if he removed the oil filler cap the engine breathed heavily, my mechanic told me that the engine would need replacing,so I should sell the car as soon as possible.
I found it difficult to believe my trusty VW was in such a bad state, as it has only done 87000s mile and has full service history and starts and runs like a dream. Today I went for a second opinion, they told me that the coolant problem was because of a defected water pump, with most likely the plastic impellers failing, and the engine breathing problem could be down to a blocked breather at the top of the engine.
IS F (2008-2014) :: Coolant Overflow Reservoir Leaking?
Experiencing a hairline crack on the coolant overflow reservoir?
I noticed a bunch of dried coolant during my last oil change, ended up tracking it to where the upper radiator hose meets the reservoir. It's leaking a few drops per week, but it's enough to be irritating. I was only able to catch it by feeling the underside of the hose.
Golf IV / Jetta IV :: 2001 - Engine Overheating - Coolant Temp Sensor Replacement
My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
Celica :: 1993 5sfe - Coolant Overflow Tank Hoses On Cap?
Just finished a timing belt job on my 93 celica 5sfe. Filled the coolant up and burped engine. All seems to be well. My question is related to the coolant overflow tank. The cap has a hose attached on one end coming from the radiator and another coming out the other side that is short and L shaped. The L shaped hose isn't attached to anything and is open allowing air to either vent out or vent in to the overflow tank. There isn't any place nearby where the hose might attach to. Is this hose supposed to be "unattached" as it is now or should it be closed to create vacuum for the overflow tank to allow coolant back in to the radiator?
