Passat (B5) :: 2003 V6 Overheating - Leak At Hose On Driver Side Of Heater Box
Jun 28, 2012
I have in the last 5000 miles had the timing belt changed and at same time the usual other item - water pump, Thermostat etc,, Engine has 155k on it.
I have had overheating issues that I thought was related to the viscous fan clutch and replaced that (it was bad) and the issue of overheating now just take longer to happen.
I have bled the coolant system and have good hot air out with heater - engine warms up within 1/2 mile of house. I am running right now Prestome all color antifreeze as it was overheating and and loosing liquid as a result.
In trouble shooting yesterday I find that when it now overheats it is leaking at the heater hose on drivers side of heater box. I have repositioned hose and clamp after bleeding it and it still overheats and with pressure build up leaks at this location - this happens when moving or when stationary.
With heat coming from heater box (both hoses get hot) and both fans working would this be bad thermostat? (again have heat) or a bad water pump?

Ok just so I know what the dealer may do to fix it....I have a weird hissing sound coming from the driver side like a vacuum hose is off or something...but when I apply the brakes it goes away...I let go and it comes back...when I shut the car off as well it stays hissing until I hit the brakes again or it just quiets down... What this may be?

So the driver side seat heater won't work, I swapped the switch with the passenger side and it won't work (but the drivers side switch works on the passener side), the fuse is alright. What am I missing?

Today I noticed a leak at the heater hose assembly at the right rear of the engine compartment. It appears to have special connectors and that appears to be where the leak is coming from.

My driver side seat heater stopped working, but the passenger side still works great, if its just like a loose switch (just had a stereo installed like 4 months ago) or is the actual heater bad itself.

98 F150 2wd 5.4 -even though VIN says its "W" 4.6; it has a 5.4 with 4.6 timing setup-found. But that's a whole other story...
So, Replaced heater core. did the blend door too.
A week later it overheated and blew a heater hose off the core at the firewall (several times). Temp was up and down, forced me into cylinder head protect mode, so i called my mechanic.
Mechanic used a sniffer (blue liquid turns yellow) in my overflow tank and there was exhaust gas in it... so we replaced head gaskets, intake, timing, water pump, radiator and the rotted out rad support.
Got it done and back on the road, but a few weeks later and the heater hose quick disconnect blew off again, spewing coolant all over (again). This was what we thought was part of the original problem- head gasket allowing cylinder compression into the coolant passages. the little rubber hose that comes from the back of the intake and goes up into the heater core builds enough pressure to pop the disconnect right off and I dont know why. Like I said- I thought it was the head gasket blowing pressure into it but that's all been replaced. Why the pressure would be so high at that point, and how do I correct this?
This is my daily driver, so for now I've bypassed the heater core, but I'm afraid that pressure is gonna burst a hose and/or fitting again.

2001 Passat Wagon ... After a heavy rain last night I noticed a very wet driver side floor area. My car was parked and I've never noticed any wetness while driving. What are the steps to take to figure out where the leak is?

Replace the seals in a power steering rack on a Passat? I recently noticed I had a fluid leak after seeing spots on my driveway. After discovering it was power steering fluid when I checked the reservoir, I checked all the lines and found the leak coming from the rack on the drivers side. The boot on the steering rack had come loose and there was fluid leaking from the side of the rack. Is there a fix for this or am I looking at a expensive repair?

I own a 2003 Toyota Camry with 195,000 miles. We have owned the car for about 6 years. It is now leaking oil from the drivers side of the head gasket. The oil has been leaking down onto the exhaust and smoking, and it has been getting worse and worse. This is a second car and is not used much, only once a month for short trips. Is there any temporary fix for this that can maybe get me through a year? Also, I have heard mixed opinions on how hard replacing the head gasket is, does the engine really need to be removed?

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.

I have a weird leak from under the car below the drivers seat. It's waxy, as though something was melting inside the door [maybe]! My mechanic ruled out oil and transmission fluid. If it's from inside the door, could face expensive repair.

Small oil leak looks like coming down by drivers side up pipe. I don't think it's the turbo o rings. Better not be. But could be I guess. Anyways. It runs down somewhere by the up pipe down onto transmission. I'm not loosing tremendous oil or anything.

I have a '02 7.3 that has developed a severe oil leak in what seems to be a small line that runs from the drivers side head to the HPOP on the passengers side.
it seems to be leaking at the braket that secures it to the head on the drivers side.
what is this line called and where can i find one A.S.A.P?

It is still a drip, but is getting worse, for several weeks. May be power steering fluid. I have not found the source. I think it is after the truck has run and has fluids operating under pressure.

I have a 2003 Escape Limited 4WD with approx 163K on the clock. It developed a tranny leak from the front driver's side axle. The seal is new and in good shape as I just replaced the axle and seal a few weeks ago. (I checked the shaft size and surface finish of the axle and it is in spec.)
I just removed the axle tonight and discovered that the problem seems to be the bushing just inboard of the seal in the tranny. The axle has movement up and down when inserted. (Not good!) This is allowing the fluid to leak from the seal.
Here are my questions. Is this a simple DIY fix using a slide hammer type of puller (or similar), or is it time to take it to a tranny shop. I can not seem to find a replacement part listed anywhere.
Also, with this much mileage, should I have the tranny reworked as a precaution if this repair requires dis-assembly or should I just address the leak and think about dumping it? I would prefer to keep it as my kids are now driving age and this is primarily their vehicle. (It has been a great little truck!)

We noticed a burnt rubber/oil smell coming from our '01 Subaru Outback, no engine lights were on. When I looked under the hood, all the fluid levels looked good, but I noticed on the left side, about two thirds down the side of the engine, there appears to be a leak of gooey brown oil? from a hose running up over the engine. Do you think this is the source of the smell? What this is, how much it will be to fix or if we can safely drive it to the mechanic (we are about 45 min from town)? See photos here: [URL] ... I tried to zoom in slowly so you could get an idea of the location.

After cleaning entire valley on my 2001 f350 with 7.3 I have found what appears to be a small leak under the hpop drivers near the IPR. HPOP lines are clean and dry. Possible for IPR to leak at 120k miles and what will need to be done to fix.

I'm having a problem trying to locate what I assume is an oil leak. It is on the driver side and the whole engine compartment is wet on the side up on firewall beneath the master cylinder. And the whole underneath is wet also axles and leaf spring and can't find where it's coming from. I have sprayed it down with degreaser to try to pin point the leak still no luck. Truck has 236k on it also new hpop and turbo pedestal and checked the valley and its dry. Right now I'm at a loss. I'm leaning towards oil cooler but would a leaking oil cooler cause whole side of engine compartment to be covered?

I'm trying to figure where the coolant leak is. Appears to originate on the driver's side front, right near the thermostat housing. Since the engine tilts back the entire drivers side is wet. The thermostat gasket appears to be OK, but it does have a lot of miles on it.
If it's not the thermostat then can coolant leak from the cross over tube. And is the cross over removable without taking off the intake. There appears to be a bolt coming up from underneath on the passenger side.
Also, does coolant flow through this plastic intake. If it does, then the leak could be some where else, if not, then it's probably the thermostat.

So I replaced my air filters today and my drivers side intake hose was wet with a brownish oily substance. I looked around for obvious culprit but found none. Looks like there is an aluminum brick there for brakes but it was shinny and clean the shock tower covers had what looked like built up of this substance. Doesn't leak onto the driveway and see no other signs anywhere else.

Yesterday, I saw a hose, ~1/2 ID hanging down from under the engine on the drivers side. Tried moving it around to see where it would reach to so I could find where it disconnected from to no avail. The end that's still connected appears to be going toward the firewall, but without living the truck I can't see where exactly it's going to. It appeared dry until I lifted and then a small amount reddish fluid dripped out. Fluid levels that I could check appeared normal. The truck seems to be running fine, engine smooth, no trans slipping, breaks normally. 2007 explorer limited 4x4 v8... What this hose might be?
