Prius (2004-09) :: Radiator Coolant Not Heating Up
Oct 29, 2010
My 2007 has 160k miles and at just over 100k I had toyota change all the fluids. That was about 3 or 4 months ago, it's a taxi. I started noticing the heat was only hot above 83, and sometimes not even hot at high. I thought I was out of fluid so I added to the overflow not wanting to open the cap on a hot motor. It didnt take much, but made the heat come back on above 80 degrees so I did nothing else.
Last night I had no heat again after driving about 200 miles. The heat came back after turning it off for a few minutes, but I stopped at a gas station anyway when I got off the freeway.
The overflow was full. It was also cold. So were the radiator hoses, but not what looked like power steering hoses next to it.
I check that belt pulley was spinning when the engine was running, it was. It a new belt put on by dealer.
The car doesn't show any signs of overheating, and is driven 300 or more miles a day in town and freeway. The motor was of course hot, but not overly so. None of the connected components were hot like I would expect if was overheating.

I replaced a failing two way coolant valve and went ahead and replaced the coolant. After this the heater wouldn't get hot, so figuring there was still air in the system I added more (which it took)...and repeated that twice. (and opened the top valve to allow it to bleed). Finally heat.
I got up this morning and the heater still wasn't working....so I added more fluid....which it needed. Now I have heat.
BUT, The engine started running like crap. Code says misfire on cylinder 1. Changed the plug and coil pack. This did not work. (When I pulled plug one out the end of it was dry.)
Could it just be a crazy coincidence Immediately after I changed the radiator coolant that a faulty or clogged injector rare its ugly head? The car was running fantastic before this. I thought, before I check the codes, that some way maybe I overheated the car and landed with catastrophic issues.
I have 378,000 miles on my 07 pruius

I have a 2007 Prius, my coolant is always overflowing to my reservoir. It doesn't have any overheating problem, if I will fill up the radiator I could see bubbles coming out, How can I resolve this problem?

So my radiator fan isn't working my ac fan is but not the other one. I knocked on it a few times and got it to spin? Also I was wondering where I could buy silicone hoses for the cooling and for my turbo the hoses i think have holes that's why the check engine light is on something to do with vacuum leak/high idle.

Our 1999 Mitsubishi Eclipse engine heated up. The Anti Freeze reservoir is full but the radiator was low which caused the car to heat up. Why isthe anti freeze not getting to the radiator? The hose seems clear. We filled the radiator with anti freeze and the seems to be working fine. Why is it not sucking from the reservoir.

I just noticed this morning that the coolant tank (close to radiator) is empty. The other coolant tank level is normal. Big surprise! I thought they are connected, and coolant can flow between them.

Ok so I have an 04 Jetta 2.0 and lately it's been overheating on me. The first time it started overheating was because my radiator was cracked and leaked out all my coolant, I swapped the radiator everything was fine for a while. The second time I started overheating, I saw my primary fan was bad it wasn't spinning at all, I swapped it everything was fine for another while. I also changed the coolant temp sensor, it wasn't bad it's just because the coolant flange was leaking coolant, so I changed it a long with the O-Rings and sensor. I also changed the thermostat just incase that was the problem but it wasn't.
I don't think the fans are turning on by them selves when they have too, but either way the car still overheats when I turn on the fans manually with the A/C. I'm not sure if the coolant is circulating, as the car only begins to overheat when I come to a stop and it idles. I have a feeling it's the water pump but I wanna be sure it is before I change it. What it could be? Things that I should check for that usually go out?

I have a 04' RX 330 with 92k. It has small radiator leak. If you are standing in front of the car and look below the fan on the left side of the radiator you can see a small amount of red fluid that has leaked out of the radiator. However, the leak isn't big enough that I ever have to add coolant I just top it off when I get the oil changed. Also it doesn't puddle on the pavement when parked.
The only thing I really notice is that my windows tend fog abit easier now so I assuming the moisture must be making its way into the ventalation somehow. My mechanic said its about a $700 repair. My question should I fix it and is $700 reasonable. Also I've never had the timing belt replaced would it make since do have this done at the same time as the radiator. How long will it take before it becomes a major problem instead of a minor annoyance?

2004 4.6 V8 Trition ,two wheel drive, STX Pickup. By removing the bottom radiator hose, will that allow all engine coolant to be drained from engine? If not, about how much coolant will remain in the engine in terms of quarts or percentage of total vehicle coolant capacity?

My girlfriend's sonata was heating up. I stopped to check the coolant and saw it was all gone. I refilled it just 3-4 weeks ago.
I've checked the most probable stuff;
-There is no white smoke coming from the exhaust
-The oil looks and smells fine
-The colour of the coolant hasn't changed
-I couldn't find any leaks (looked with a flashlight for a few minutes with the engine running, there were no obvious leaks)
I really can't find what's wrong with it.

I bought my 07 salvaged (but already fixed) w a front end collision. After driving up a mountain road, it overheats. I checked it out and the radiator and condenser fans are both blowing out through the grill. This is counter-intuitive and surely must be due to swapped wires, but after checking the wiring diagram both motors get their power well upstream from each other. Hard to believe they could have wired both motors backward.

How the radiator fan goes into high speed? My 2006 Prius A/C works great as long as I am moving. But when stopped in traffic or at a light, the radiator fan does not go into high speed. So the A/C shuts off until I can get cool air back through the condenser.
I replaced the two fan relays, and when I do the fans run into high speed for a moment, then back to slow speed. Is there a temperature sending unit in the Prius I can replace?

I replaced my upper radiator hose on my 2000 vintage TC 4.6 liter V-8 yesterday and normally I would add coolant through the top radiator cap and not the overflow reservoir.
Apparently this car does not have a radiator cap and has only the overflow reservoir tank to add anti-freeze. Checked the owner's manual and my Lincoln repair book, they just said to use the reservoir tank. While I did not loose or have to add much, what if I had to replace the lower hose, or the radiator itself with all that coolant gone?
In other words while I am waiting for the overflow tank to add anti-freeze while the engine is running, I am operating a car with out enough or no liquid at all which seems nuts, is there some technique that I don't know about to add anti-freeze?

I am driving smoothly on the highway, doing about 60km/hr, with my A/C working on a full. Suddenly, the check engine and emergency brake light comes up on the HUD along with a beeping sounding. A pull over, and smell a bad odor - like burning rubber - coming out of the hood. I checked and the car was immensely heated and there was smoke rising from a small rubber tube right next to the fuse box under the hood. I turned off the car.
Whenever I would turn the car back on, the smoke would start coming back. I checked several times. I couldn't find out where the smoke was coming from.
When the car cooled down a bit, I checked the radiator. The coolant level was a bit low so I filled up with the water. I also noticed that the radiator fans were not working, even when I turn the A/C on. So I called a towing company and got my car back to my garage.
Now the car heats up after running for a bit and the big exclamation mark sign comes on. The check engine light also comes on. But when the car cools down, the lights go away. I am thinking that the problem has something to do with overheating and the radiator fans not working.

I noticed a 1'x2' square in the bottom passenger side corner of the radiator covered in green oily gunk. Ive had the 2008 for about 1000 miles (has 58k) so Im assuming its been there for a while. Seems like its impeding airflow. Its very green.

I have an '09 Accent, with 102,000 miles on it, it is in good shape, and current on all its maintenance, however, i am leaking coolant via the radiator cap, and don't know why. It has been replaced twice, once by me, and once at the dealership after a pressure check confirmed i was not leaking anywhere else, ie: into the engine.

My elderly mother brought a used 2006 Volvo SR60, in 2008. Later she discovered that the radiator light/coolant would blink on in the car. The Coolant was low. She took the car to To Mckevitt Volvo here in the Bay Area. The car was under warranty. McKevitt replaced the radiator
Apparently she kept having problems with the coolant system in the car. She took the car to another car repair place (Ackerman) and they detected a tiny crack in the radiator, but they said it wasn't enough of a leak to cause the leak. Then they suggested replacing the thermostat of the car. Apparently, this is a real costly procedure costing hundreds of dollars. She opted not to do this..
Recently she took the car back to McKevitt Volvo, still because of the coolant problems, the car is no longer under warranty,, Mckevitt held the car for a couple of days, after an inspection for leaks, they told her they could not find any leak, although they cleaned up the car, and didn't charge her for their services.
So now she's paying on a newer model car, , that leaks coolant, but no one knows where....
Does she still have any recourse, what should she do? She's an older person in her 60's so she needs her car and doesn't need a blown head gasket. I suggested, trying one of those "over_the_counter_" radiator, coolant system seal, to stop any leak, are these safe to use?

On my way home from work, after driving about 45 minutes, I stopped at the Post Office. On the way out I noticed that coolant was leaking. I was able to make it home without overheating. My guess was either the water pump or a hose.
This morning I physically checked the hoses and they seemed fine. I filled the radiator with water and started the van and let it run until it got hot. I watched to see if I could tell where the leak came from. I could not get it to leak, after 15 minutes I gave up. I know it was leaking yesterday, not only did I see green coolant, the radiator was low on coolant.
What should I do to further diagnose the problem?

1999 E350 V10 van, 120,000 miles. I'm the second owner so history unknown.
After driving this past Saturday noticed coolant on the pavement when I parked. Checking inside I found coolant all along the top of the radiator where the clips secure the plastic tank/cover.
Reserve was half full where I keep it. Running the van while parked and the temp was less than mid range. Can I assume the radiator is shot?

Just wondering if there's been any incident where the coolant in the SC430 is leaked into the gearbox at the radiator. I mean, these cars do have the transmission fluid running through the radiator, right? I've read that this occurs a lot on LS430 and many Mercedes models.
Would it be a good preventive measure to replace the radiator anyway? Or, is it ok to wait till there're signs of such leakage (if it doesn't usually begin as a major leak)?

1999 Honda CRV. Took it in for an oil change last month, then next day took a long road trip. After the first half of the trip, I opened the hood and saw colored fluid sprayed all over the front of the engine. It seemed to be coming from the top of the radiator. I assumed the common failure mode of these radiators, ie that the joint between the plastic top piece and the aluminum radiator body was beginning to fail. The overflow tank was empty, but the radiator was still full.
But before I drove the return trip home, I replaced the radiator cap with a new one just in case. When I got home, I checked the engine compartment again. No more coolant spray. So I thought the new radiator cap had solved the problem.
So I added fluid to the overflow reservoir, up to the "minimum" line. A few days later after some local driving, checked again. Again, coolant sprayed around, seemed to be coming from around the cap, overflow reservoir empty, but radiator still full.
Now I just leave the reservoir empty, instead of filled to the "minimum" line. The radiator is not leaking, because I've checked the level several times since and coolant is always near the top of the neck. The only problem is when I add fluid to the "minimum" line in the reservoir, which results in coolant being sprayed out (apparently through the radiator cap, both the old cap and the new one). Now I suspect the oil change mechanic also checked my fluid levels and added coolant to the overflow reservoir, which resulted in the original "spray" episode during my highway trip.
So the question is, why is this happening all of a sudden? Never did this before. Now I just leave the reservoir empty and check radiator level occasionally. But I would like to know why any fluid added to the reservoir when cold causes the radiator cap (apparently) to blow out the excess coolant (it is NOT leaking from the overflow reservoir).
