99 Intrigue with 3.5 has slow coolant leak at crossover. Would like advice on use of a coolant system sealer and what specific sealer to use. Car has 215XXX miles on it and otherwise no problems.
View 3 RepliesSo I have had this code P0442 for a long time and I just kept clearing it. The attached picture (at an angle) shows the hole in the small line attached to the fuel neck filler exactly behind where the plastic wheel well cover touches it. Just ordered a new one from rockauto for about 65 shipped.
View 5 RepliesI have a leak between the metal and the plastic of my water crossover.
Do I need to remove the manifold to replace the gaskets for the crossover and if so looking for a good thread showing how.
What are the hose lengths for the 2 HPOP and cylinder head oil crossover line? How about what size oring boss fittings you need into the head?
View 1 RepliesHave a small coolant leak. The level is dropping and I can smell it but I cant find it. The radiator was new at 100K miles and the heater core is bypassed. No evidence on or near the hoses, water pump or radiator. Getting ready to replace all the hoses because they are overdue but I would like to find the leak(s) first.
View 5 RepliesBack again, with the 1994-ish Volvo 940 with many miles on it.
Symptoms reported by son: coolant leak near firewall (radiator hoses replaced a few weeks ago); maybe some pressure in cooling system; some oily stuff in the coolant in the radiator.
Shop's diagnosis: transmission cooler leaking. (Well at least it's not the head gasket!)
Recommend : Replace radiator, cap (sure), thermostat (all right, but we get rid of this car in six weeks), and ... flush the transmission (alarm!).
Usual advice is drain and refill tranny, rather than flush. However, seems to me that with high risk of coolant in trans fluid, flush is the right action.
I think that it is coming from the hose that connects right to the reservoir. I have wiped it clean a few times and it always seems to be seeping from that area under the hose where it connects to the bung. I replaced the OE hose clamp with a new one and put some electrical tape around the hose but it still leaks. It does make a slight hissing sound from the area as well when I pop the hood after a long ride, but only lets off a few drips. My guess is that I may have to replace that entire hose but that looks involved as it is attached to several others.
View 4 RepliesYesterday my car threw a CEL for the first time; I am currently APR stage II. Ran the code and came up with P2400. Code cleared, but after 1 cycle it appeared again.
Interestingly, on my way to a cookout today the car started yelling at me about low coolant. I pulled over and checked but didn't see any initial signs of leakage (was raining at the time though...). Continued to my destination and topped off with distilled H2O in lieu of G12 since I didn't have any immediately available. Once I made it back home, checked the reservoir again and saw that the level had dropped (probably ~ 1/2 cup or so). This time, I could see liquid on the belly pan, then on my driveway...
It looks like the P2400 code is indicating an issue in the leak detection pump circuit. Any chance that the coolant leak and P2400 code are related (leak shorted something out...??? I should mention I am not super familiar with the plumbing for the evap system in this car) or am I really this unlucky.
Issues with the car since purchase:
- Replaced clutch (stock would not hold stage 1 torque...)
- Wiring for radiator fan came loose, fans stopped working (took ~3 weeks to resolve due to resulting ECU issues...)
- ECU solder joint (EVAP circuit) damaged during re-flash after flashing to stock for dealer to address radiator fan issue...
- P2400 CEL
- Coolant Leak
Van has 144k miles on it. It's been well maintained (see my other posts). I have had it since new (7 miles). The LIM was done preventively at about 75k miles (5 years ago).
Two to three years ago it started using/leaking etc coolant at a very slow rate. I would estimate somewhere in the 8-10 fl oz per 3-4 month range. As time has gone on it has been progressively using more. Now it is about 12-14 fl oz in about a month or 6 weeks. My "low coolant" indicator came on the other night. It had been a while since I added any coolant mix. 3-4 months anyway. It took about 1/2 gallon (US). There has been no "real" visible leak,up to now. I noticed yesterday when I was under it doing an oil change, that there was a "film" on the bottom of the trans pan. I followed the trail as best I could and it led me to the rear of the engine near the drivers front wheel. It was a small drop of coolant. (I tasted it). Don't try this at home... From the top of the engine looking in, I followed the upper radiator hose to the thermostat housing "pipe". It is very difficult to see in there. I took a few pix. [URL] ....
It looks like there is a little pool of coolant sitting near or under the thermostat housing that pools on top of where the transaxle bell housing meets the engine block. It's very hard to to see in the pix. Some of what looks to be damp, is actually shadow. This pool I believe runs down the back of the engine/trans, and then is blown on top the trans pan and undercarriage.
The van runs great, I want to keep it for the next 9 years. There is no coolant in the oil, or oil in the coolant. Unless the fix is fairly easy, the leak is still small enough that I am not going to bother with it until it becomes a large leak. The car runs cool even in the hot summer pulling a load. The only issue is the leak and that I have to add coolant every once in a while.
I have a 97 Cadillac deville with the north star. My problem is I have a bad coolant leak coming from the right side of the car. You can see that it's all wet on the right side but I pressure tested it and it holds pressure and nothing leaks. Where it is wet it looks like it came from the overflow drain tube and it looks like it's been blowing back. I've been going through a lot of anti freeze but it's like chasing a ghost you can see it's wet but under pressure it doesn't leak. It does not overheat. Can it be the water pump?
View 6 RepliesRepaired a coolant leak under the intake? I just repaired the bad o-ring and rtv at the front coolant bypass joint. But, there is still active coolant leaking around the back side of the block and puddling on the garage floor beneath the front of the transmission each night.
So, I'm guessing I need to start removing the intake to hunt this thing down, the top of the block, just under the intake is constantly moist. But I'd like to have a list of seals and parts I'll need to replace before I start.
My 2001 Prius with 134k miles has been running great but leaves a small amount of coolant on the ground after parking. I've had to add approximately 8 ounces per 100 miles.
View 13 RepliesI went on vacation, my 2.0T B6 developed a coolant leak at 35k miles. It's still in the shop but the problem has been identified as a leaky o-ring located toward the rear of the engine at the block. The SA told me that they've see quite a few of these in both Audi and VW products using the 2.0T.
I'm also getting a reflash for one of the recalls. I think it's the 03 recall but I'm not sure until I get the paperwork. So off I go in my loaner PT cruiser until I get the B6 back today....
I have a coolant leak that appears on the outside of the transmission. The Toyota dealer tells me it is an O ring between the transmission and the engine, and this part is not individually replaceable. The dealer says there is a lot of rust in the transmission, which is what caused the problem, and they want $1800 to replace the transmission with a used (125K miles) one.
The Prius is a 2004 model with 100K miles on it.
So I started the car today, proceeded to back out, and the STOP: check coolant light message comes on. I check the coolant reservoir, and its near empty. Then I notice a puddle. Filled it back up and let it run for a bit. No leak. Looked at the front of the engine and didn't see any leaks.
View 11 RepliesYesterday after getting to work i noticed a few drips from under the front of the car, at first i shrugged it off thinking maybe it was condensation or whatever. After coming back to my car about 5 hours later it had made a good sized puddle under the car and i knew something wasn't right. Well on my lunch i got under it and collected the liquid only to find that it was coolant. To make matters worse on the drive home my temp gauge would go to operating temp then drastically drop to almost cold temp.. weird. And last but not least when i parked the car at home i noticed that the cooling fans did not stay on after the car was off, since it was about 95deg this seemed wrong. Took the car to the dealer this morning and I'm hoping its just a loose pipe or something little and not anything that will keep it in the shop for a long time. Car is completely stock except for cat back exhaust, 12,000 miles on the odo.
View 6 RepliesNoticed about a gallon of coolant on my floor the last 4 days. Got it pressure tested and was told bad water pump. Had it changed with timing belt and tensioners. Got home, next day, same thing. Coolant everywhere. Also, do I really need to put G12++ in as coolant? I've been using it but the shop put some green stuff in it.
I have a 2005, V8, Phaeton with 181,000 miles. Also, my car overheated, got the coolant too hot warning, 270 on gauge, let it sit 5 minutes, no problem afterwards. Should the thermostat have been changed also?
I have noticed my 2007 SF V6's coolant is reducing at reservoir. I added premix coolant about 1 liter a month ago. Today I saw my driveway was wet, and this hose end was leaking.
I turned the spring clamp about 90 degree. but it's still dropping like 1 drop per 1 minute or so. Is this common issue? and how can I fix this?
Should I change the black hose? or change the same new spring clamp or change the spring clamp to a wider screw clamp?
Also, when detach the hose end, some amount of coolant will come out then, just adding premix coolant into reservoir for the max level is good enough? or do I have to bleed radiator airs?
I think its a flange that connects to hoses, they want to charge me 140 to repair. would this be something i can do myself?
View 5 Repliesmy audi tt 2003 convertible turbo has had trouble starting. the engine turns over just fine and up untill now it has caught, albeit a little slow. now I note that it still catches, about every 3rd try, but unlike before it isn't staying on no matter how much I try to rev the engine. We just had the spark plugs and 2 coils replaced. There's a coolant leak through the sensor housing (we have the part for that but hubby doesn't want to fix it) but we do keep coolant at sufficient levels. problem seems to get worse on colder mornings, but is not affected by cold in the evening. Yes, the check engine light is on. The codes have been read and it's coming up as the temp sensor (which part we purchased, but hubby doesn't want to install).
View 3 RepliesI've never had a leak before in my anniversary and now all of a sudden I have a coolant leak. Once I start the car and run it for a short time and shut it off I lose a few ounces of coolant. I inspected under the hood and the coolant seems to be leaking onto my tranny. I am unsure where exactly it is coming from.
