My serp belt squeaks due to contamination due to timing cover leak. I removed belt and cleaned it with mild degreaser solution and it was quiet for 1 day. If I had 100% water in cooling system, would any more leakage cause a belt squeak? I am putting off fixing timing cover gasket since it is a 5hr job. Coolant is @ 90% water concentration now.

I have a 97 Honda Accord with V Tec engine, 2.2L. I have an oil leak that is coming from BEHIND the timing belt cover. I removed the cover and the belts to expose several seals. The oil leak is quite extensive and leaves a good puddle after running the engine, however, it will not leak once I clean up the mess, put the car up on jack stands and disassemble the engine. I cannot tell which seal is leaking and am wondering how to tell which seal is leaking. Is there a way to apply pressure to the engine with air, possibly through the oil dipstick hole to possibly expose the leaking seal?
View 9 RepliesSerpentine belt on a 2006 Honda Odyssey fraying and then ripping into the timing belt causing that belt to break? I recently had this scenario given to me as the cause of my recently replaced timing belt breaking.
View 11 RepliesBeen trying to isolate my noisy serpentine belt. Had the belt off and spun everything, only thing I found that made any noise was the alternator. It had a nice churp like a bearing was on its way out in it. So I replaced that figuring my squeak was going to go away. No such luck. Listening to it again while it was idling, I crawled underneath. Almost seems like the churping noise is coming from the Crank Pulley. Is there a bearing on this pulley that goes bad?
View 13 RepliesI noticed my serpentine belt started squeaking about 3 days ago. And yesterday as I was driving to work I heard a clicking sound coming from the left side of the hood, then my car started to gradually shut down and white smoke was coming from the engine. When I got to the stoplight it completely turned off, but I was able to turn it back on again to turn into the parking lot before it shut off again. When I checked it there were no visible leaks, my reservoir for my coolant was still full, and my meter never went up indicating that my car was over heating. I'm not sure what's wrong with it, but after it sits for awhile it is able to turn back on again for a while.
View 3 RepliesToday I had my 2004 1.8T Passat in the shop for a few minor things. The car has only 89,000 KM's (NOT MILES~ I live in Canada) on it. They told me that my serpentine belt was needing to be replaced (which I knew) and they recommended that I to my timing belt at the same time. They told me that you can buy a kit that has the timing belt, tensioner and water pump in it. Anywhere I have read it has said to change your timing belt at 120,000 KMs.
View 2 RepliesWell, started to get belt squeak during cold starts. The idler pulley was changed many miles ago for same issue, but it seems to be starting up again. There are NO tutorials for serpentine belt replacement on this gen of RX.
View 14 RepliesSo my mk6 developed what initially sounded initially like a bad serpentine belt tensioner. Only under anything more than load, and sounded like a bird chattering under the hood. Got outside today, fired car up, watched tensioner and it sat there steady as a rail. The noise is coming from the opposite side of the engine. Not really mechanical/metallic at all and tracks under load with the RPMs. Why i initially thought what i did. Not I'm sort of baffled.
View 3 RepliesThe serpentine belt starting squeaking on cold and damp mornings about 18 months ago at about 60K. I replaced it with a Dayco belt, and the noise went away for about 6 months. When the weather turned cold last winter, the noise came back. So I changed the tensioner with both idler pulleys right about when the weather warmed up, and it was fine all summer. Now that it has gotten cold again, the squeak is back yet again and as before it goes away when the car warms up. I know it is the serpentine belt because when I spray it with water the noise immediately stops. I checked all the pulleys with the belt off and when I spin them I hear no noise. Is there something else it could be?
View 1 RepliesIn a few weeks I will be bringing my new to me Ranger back to the great state of Texas. The truck however, has a squeak when running, which I think has been concluded as the idler pulley for the timing belt. Well, I'm nowhere near the truck still and in order for it to get here it will need to be driven half a day to reach me, at which point I could do all the work it needs done.
My question is: Should I take the risk and have it driven here before the belt change (I did look at it while I was out there and it's already cracking pretty good), or should I go ahead and have someone get the belt done at a shop? It's less the belt that concerns me I think, and more the pulley, even though it's just started squeaking in the last 1000 mile.
My truck has had this annoying tendency to drink coolant. I believe I took care of it by replacing the thermostat gasket. Not so, it drinks about a quart every 50 miles - so quite a bit really.
Finally bit the bullet and took it to the dealer so that they could figure out where the coolant was going.
Answer I got back was - timing cover gasket, water pump, lower radiator hose.
The water pump appears to be good, its just the gasket that's bad. So my question is - how significant is the timing chain cover leak? Poking around online it appears to be reasonably common, but sounds very expensive. The dealer indicated it would be 2 days work minimum.

I've been plagued by a belt squeak for several months now that only seems to occur when I'm in motion and let off the accelerator. I'm thinking it's the timing belt so I took the top cover off to have a look. What I found is the belt is a bit off center on the top sprocket, although it doesn't look frayed and isn't hanging off the edge.
I found that the tensioner seems to wiggle slightly when I try moving it by hand. It doesn't look like it wobbles when the car is running, but I've never been able to see in the engine compartment when the squeak occurs. The belt also appears to have some shine on a line down the center. Pictures attached.
FWIW, I checked for play in pulleys on the aux belt and found none. What's everyone's opinion on the tensioner and the condition of the belt? The belt has 52,000 miles on it.
I have some serious work that needs to be done on my car. The catalytic converter needs replacing, and the valve cover gasket and cam adjuster seals need to be replaced. This work falls under their respective warranties. However, I'm wondering if I should have the water pump and timing belt done at the same time as I have 77000+ miles on my car. Is there anything else that would be good to do at the same time as this work. I would be going back to the VW service center for these repairs. Would it save me any money to do this all together?
View 4 RepliesI have a coolant leak from behind my timing cover found while doing a coolant system pressure test. I do not want to remove the engine. Looking for info on successful cover install with the engine still in the truck?
View 8 RepliesMy 2003' Explorer XLT (4.0L V6) has an oil leak. I tracked it down to the passenger side, rear, bolt head on the valve cover (back by firewall). I took it to a guy who replaced the valve cover gaskets, but it is still leaking. He claimed when he had the cover off he looked for any cracks on it, but did not see any at the time.
Anyways, I was searching around and found several explorers leaking in or around the same area of the valve cover. And it turned out that there issue stemmed from bad timing chain guides, causing the valve cover to crack.
I do notice that on a cold start, I hear a rattling when I first start it up. It rattles for maybe that first 1-2 seconds when starting. Is this my timing chain rattling around? If that is the case, how much this could set a guy back on repairs?
I guess I don't know whether to just replace the valve cover, or if I should dig into it to see if the real issue is the timing chain guides/tensioner. Mileage is approximately 121,000....
I have 2000 V6 3.0 Ranger and it has sprung a small coolant leak from timing chain cover gasket. I think just few drips after driving a while since I don't see significant drop in coolant level (Took a month to notice level dropped in reservoir) and did not see an active leak while idling. No water in the oil.
The proper repair would be to replace the gasket, but for the age and condition of the truck, I don't think it is worth it. Searching for a cheaper solution, I found K-Seal and see lots of reviews with success. Will it damage the cooling system in anyway? I think it would be worth a try even if it doesn't fix the leak as long as it does not cause any harm.
My serp belt started squealing so I pulled the thermostat housing to inspect the rubber gasket. It looked OK, but I cleaned up both surfaces and replaced with a new gasket, and put it back together. The housing was replaced just a couple months ago along with new hoses. It was not corroded and OK to reuse.
Started the truck up and saw a slowish/steady drip of red Cat ELC dripping on the driveway. Opened the hood up again and carefully inspected around the thermostat housing - no coolant is leaking there.
I did notice the same slow/steady drip coming from just behind and beneath the thermostat housing. See in pic, this is where it is dripping. One other question, what is this plug for on the side of the water pump?
Is this common? No coolant in the oil-YET........
Any way to fix it without pulling the cover?
I have an '04 Ranger Edge 3.0 with a severe coolant leak. It appears to be coming from the area where the head/water pump housing meet. I have been told I've lost the seal behind the pump on the timing cover. Is there any way to know for sure? Will I be able to tell, once the pump is out that it isn't coming from the head side? Are there any "special" instructions for re-sealing after replacing pump?
View 6 RepliesI understand the TSB for this issue relates to 2005 and 2006 model Avalons. what's your best guess in terms of how common the timing cover oil leak problem is on '05s and '06s? 20%? 80%?
View 11 RepliesWas told my Sonata has a leak at the Timing Cover Gasket by two different service stations. Took it to the Hyundai Dealership and they said they would need to pull the engine out to fix it and it would take a couple of days. I read on a couple of other posts that people were able to replace the timing cover gasket themselves. So, I don't understand why the Dealership said the engine would need to be pulled, but I'm reading others say they fixed it without pulling the engine. Am I missing something...? I'd rather not have the engine pulled out if it doesn't need to be.
