Toyota - Avalon :: 1999 - Radiator Coolant Leak?
Jul 31, 2016
I drive a 1999 Toyota Avalon XLE and my radiator is leaking coolant from what looks like 2-3 spots. I replaced this radiator and the new one is leaking it is pooling very lightly on the top in the ridges of the radiator, and dripping on both sides below. I want to say it is the lines but i got new clamps and I even went as far as to spray silicon on the hard plastic piece the large softlines attach too so that inside under the clamps it would form a seal. the radiator I got is a Silla radiator if that matters

1999 Honda CRV. Just took a 3-hour highway trip. Before trip I topped up coolant reservoir which was a little low, but radiator was full. I did notice some dried white spots on the front of valve cover and spark wires. Wasn't sure what it was, but now realize it was coolant residue. Probably only 1-2 cups were missing from the reservoir, so the leak had just started.
After 3 hour trip, checked engine compartment again. This time the reservoir was totally empty (radiator still full) and the engine was well sprayed with greenish coolant residue. The radiator was cool by the time I checked it, so the leak source wasn't obvious, but it looks to be coming from the seam where the plastic top meets the aluminum.
I will replace the radiator when I get home, but first have to drive the 3-hour return trip. Will it be OK as long as I start full of coolant and keep an eye on the temp gauge?

About a week ago I began smelling coolant after driving my 2012 F350 6.7. Yesterday I noticed a small amount of coolant on the ground and decided to take it to the dealer. As soon as I told the Service Manager what was going on he said......"You need to leave it......there is no doubt in my mind it needs a radiator". They pressure tested and and sure enough it does. He said they are replacing about 2-3 a month but there is no recall.
Here is where it gets fun. Apparently radiators fall off at 36,000 miles and are not included in the 100,000 Power Train Warranty. It gets better. The Radiator is on national back order for 5-6 weeks.

I'm trying to troubleshoot a leak on my 08' F250 with a 6.4 powerstroke. It's been dripping coolant when cold pretty aggressively. Once the truck heats up, the coolant leak seems to mostly go away.
Here's a picture of the drip, it's marked by a dart, so you can see the location from the top (second pic). The radiator house connection around the engine seems dry.

What's hidden here that could be causing the leak?

99 Toyota Avalon, 3.6 L engine, 160k milesThe engine sends radiator fluid to the overflow reservoir but doesn't suck it back into the engine when it cools.My mechanic replaced the radiator, cap, and hoses...no change. So. he put a chemical in the radiator fluid that is supposed to form a plug to stop a leak. After ~5 months of waiting, still no plug...no change. Tomorrow, I'm bring it back to him. If he says it needs a new head gasket, do you agree? If so, what would be a reasonable cost? Also, this timing belt has 68,000 miles on, do you think I should have him replace it, too (since he is doing work on the engine)?Do you think I am foolish to put the cost of repairs into this vehicle? The rest of the vehicle is good. We've had it since 2000 and have kept up with maintenance and services.

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)?

My wifes 2002 gls has a coolant leak from the top radiator hose. I put a new hose on and two new clamps on the leaking end and it still leaks!! I have never seen anything like this and I am not sure how to stop it.

I have a 1996 Honda Accord 4 cyl. with 150 K miles. Had a coolant leak that the shop fixed. About 60 days later, same problem. I have to refill radiator every other day. What I noticed is a brown soft muck buildup at the radiator cap area. Also the car seems to run rough on and off. The underside of the oil cap is clean, no carmel color ( oil and coolant mixture) buildup.

I have serious drain now on the left side of the vehicle, and it appears to come from the radiator itself. Coolant consumption is approaching fuel consumption. Replace the radiator in a 2006- W12? Looking for some info on similar leaks and found them not originating from the radiator?

I got home tonight and smelled coolant. Looked under the car, coolant everywhere. I see the issue: a big hose (maybe 2" in diameter) has a tear in it and is spraying out coolant. I'm going to replace it, but once I do, how should I add coolant back into the radiator? Do I just pour it into the overflow?

I have coolant disappearing but no signs of a leak anywhere. Oil is fine. Car does not run hot. There is rust in the radiator though. Heater core is not leaking. I have a 2001 Pontiac Gran Prix GT. There was a recall on the cooling system but was not serviced (I didn't own car then). A pressure test was done and it holds pressure. Should I change radiator and thermostat? What else should I have checked?

I am in the middle of a several thousand mile road trip, and I am with family in Utah when this evening I noticed a puddle under my 6.0 Excursion.

The fluid does not smell like typical coolant, but from the location of the drip, I cant think of it being anything else.

I did a search but found nothing on a coolant leak. My 07 (57K) has developed a leak on the passengers side of the engine. Not sure if its the water pump (not making noise) or the themostat housing as a mechanic who took a very quick look at it suggested. How hard it is to get to the thermostat housing? Anything else have to come off? I don't have a FSM.

I recently purchased a 1997 Volvo 850 and a week ago it began leaking coolant. Currently I am having to refill the coolant every three days.
I have attached two pics. One is a pic of where the coolant pools and the other is a pic of where I am pretty sure the coolant is leaking.
The leak appears to be coming from the connection point at the top driver side of the radiator. I know there is a hose on the same side at the bottom of the radiator directly below the one in the picture. At first I thought that was the source of the leak but later found it was just run off from the leak above.
Does this a common and fixable leak? Or if it is likely an expensive fix? Any other troubleshooting I can do on my end or do I need to take it to a dealer to find out what is going on?

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?

I just bought a used 09 yaris, 5 speed manual tranny. There seems to be a small coolant leak on the top hose coming from the radiator, the one that connects to a plastic flange or adapter and then go's to the engine block. The car does not get hot and it drive fine except it leaks at that spot. I try using a regular hose clamp and still leaked. Is the thermostat not opening up or is the water pump intermittent stopping? or something like that. Or maybe the hose itself is bad. Since this is a used car who knows what the previous owner did, I might change out the hose over the weekend and replace all the coolant to the correct Toyota long life system. to be on the safe side.

2007, 4.0L, Explorer, 113,000 mi. Week ago noticed coolant expansion tank empty while hot and cold. Looked inside ex. tank and looked like it had not seen any action in a while. Looked inside radiator and coolant level was about 1 inch to 1.5 inches below bottom of rad. cap would be...approx. level with rad. seam, where black plastic top of rad. attaches to metal portion of rad. I filled expan. tank to "cold fill" line. Kept an eye on it while doing light, around town driving. The expan. tank level (cold-fill) didn't change.
Friday, my wife returned from work (30 mi., interstate drive). After being parked for 45 mins, went out to find fluid puddle at very front of car. Expansion tank was empty. Looked in radiator, and it was about one inch to inch and a half below bottom of rad cap...about level with rad seam, where the black plastic top is attached to metal. I topped off the rad. this time, along with filling expan. tank to cold-fill line. Turn car on, and after warming up coolant starting coming out from what appeared to be the seam at the top of the rad., where the black plastic portion meets the metal part of the rad.

On Friday am I noticed a 6" sized puddle on the garage floor. Coolant leak on the drivers side coming off the frame. Dropped it off at the dealer on Sunday and today the tech tells me it was in fact a radiator leak and the new one will be here wed. They hope to have it buttoned late Wednesday. I am assuming all will be covered under warranty.
I have 23k miles logged and had just got home from a 1300 mile run pulling about 18k worth of hay and trailer. Truck performed flawlessly. Averaged 11mpg for the trip. I am hoping this is the first and last radiator replacement I have to go thru.

Just had to replace radiator at 38k on my 2012 SD. Now I have another leak at 41k. Looks like it's wherever the lower radiator hose leads. Kind of a weird junction. I don't think it's coming from above there, but not sure. It's the primary dgas bottle that was low. The radiator was covered under my ESP. We'll have to see what's up with this one. Been eying a denim blue SD at dealer, thinking this is going to talk me out of it though. Not especially happy right now.
