If you can see and access the crack, a two-part epoxy or something like JB-Weld can be great for a temporary fix. This page shows the process on a metal radiator for a race car, but your fix would be similar. Clean the site of the repair, and rough up the surface with fine sand paper, especially if working on plastic. Mix the two-part epoxy and generously ...

I think the overheating episode did a permanent damage to your car. A gasket could have cracked or the head could have warped or even cracked, thus allowing water into the engine itself. Too much heat in an engine can cause serious problems because heat causes metal to expand. The hotter the engine gets, the tighter clearances become until there are ...

You want to make sure you do not put tap water into the cooling system on your vehicle. The cooling system has a leak, which is why you need to refill it periodically. Look on the ground where you park and note any wet spots. Check all the hoses to and from your radiator for any signs of a leak such as wet fluid or runny looking patches of evaporated fluid ...

There are several places water can get into the cabin of a car, some of the more typical are: Through tired door and window seals. Through drain holes in the floor. Condensation from your breath and/or the air-conditioning system. brought in on your shoes, clothing etc. through rust holes, missing bungs, etc. Explicit leaks would result in more water when ...

Putty/epoxy works but here's a handy tip I picked up from my materials professor to ensure that the crack doesn't propagate: Drill small holes at the ends of the crack to arrest its growth before using metal putty/epoxy to seal the existing crack. My dad used to own a Maxima that developed a crack in the radiator's aluminum head. The mechanic he took it ...

Nick C pointed some good things to look but forgave one important thing in my opinion. First let me ask you a question : Do you have many trees near your house/where you park your car or near the parking at work? If so my bet would be clogged drain from the bottom of your windshield. In my short experience with car all the time a car was leaking inside this ...

For the sake of having answers for questions, I agree with the comments, and believe this is just condensation coming from the air conditioner. You know how water collects on the outside of a cold glass when its warm outside? The same thing happens on the cold coil inside your AC system. Some cars just have a hole in the firewall that the water drains out ...

After removing the seat and looking underneath the carpet, there was no evidence of leaking from the heater core. It was rain water, about three gallons of it. Where did this all come from? Nothing from the doors, windows, or underneath the frame of the car. All of this water came from two sheets of metal joining behind the back of passenger brake light. ...

Certainly sounds like the heater core is leaking coolant into the car's interior. Like Ducatikiller said it should smell a little bit sweet, but if you still can't tell stick your finger in the fluid and give it a rub-test. You will be able to tell water from engine coolant by how it feels. Also have a good look at the floorboards and the firewall in the ...

In most vehicles the seal on the water pump will fail when the bearings go bad, or something else bad happens to the pump. Water leaking from the pump is almost always an indication that the pump is shot and needs to be replaced. Of course, also check all your hoses for bursts or clamps that have come off. The water might look like its coming from the ...

Circling back to post the resolution. I was afraid that the block was cracked, but was hoping that it was the freeze plugs. A quick survey of mechanics that have worked on Nissans suggested there was about a 50/50 chance. Had to take it to 3 different shops, but finally got the tranny out and it was the freeze plugs after all. But once they fixed that and ...

It's been a while since I've seen one of these engines. IIRC There's a water pipe that runs through the engine V and connects to the heater hose at the rear of the engine. One of these is true. The pipe is rotted The hose clamp failed The hose failed A freeze plug failed

The air con water outlet pipe might be clogged. Get it cleaned by a mechanic. Happened to me some time ago, cleaned the outlet and now everything is fine.

While I know you're asking about fit specifically, keep the following in mind, which I found on a forum discussing the differences between the N54 and N52: Both engines have an electric coolant pump, but the N54 has a 400W pump (9000 l/h), while the N52 has a 200W pump (7000 l/h) While the 528 is normally aspirated and probably doesn't need that extra ...

Had a similar problem, open the hood and look under the wipers. If you have a plastic tray under the wipers, sometimes the drain hose gets clogged with trash and needs to be cleaned. In my case it poured under the glove box until fixed.

When you replaced the thermostat did you run your finger around the coolant area to verify any sludge, metal, or contaminants? Helpful intake video: GM 3100,3400 Thermostat Replacement. I would also make sure you didn't accidentally disable something. Per memory the Chevy Lumina uses the 3.1 that is known for intake leaks. I would suggest looking to ...

This is a two part answer. The second is depending on whether there is an issue with the first part. First, it could be the drainage channels are blocked which should be toward the front of the vehicle. If you have an electric sunroof, you should be able to run it towards the rear the vehicle and see them in the front at the corners. If you poor some water ...

If it is one of the veins that is cracked, in an emergency it is sometimes possible to cut the vein and then fold both ends over a few times to seal them. A pair of long nose pliers is usually all you need to do this.

The best success I've had drying any carpet is with an upholstery attachment on a carpet cleaner or with a shop-vac. Since it smells damp maybe it would be a good time to use a carpet cleaner on the whole thing. If you don't have one of those they have vacuums at car washes that should work. Some Damp-Rid might help dry it out and help the smell after you ...

I went down the route of some all weather sealant in the end, covered the entire channel where the two panels meet, along with each mounting point for the roof rails. Before applying I removed any previous sealant and cleaned with degreaser, seems to have applied well, fingers crossed it keeps the water out when it next rains.

The problem more than likely is the drain tube for the A/C unit is plugged. Where this drains from becomes filled up after a bit of use from the A/C and has no place to go, so drains into the passenger side of the cabin. To fix this, you need to find the drain tube. This is usually located on the passenger side of the vehicle by the firewall (usually ...

There is no way to put sealant around the outside of the housing to get it to stop leaking. You could possibly put a sealant within the coolant system, such as Bar's Radiator Stop Leak, which may or may not solve your leak issue temporarily (may solve it permanently, but I never trust it). Your better bet is to just replace the gasket. This is a ...

If this vehicle has air conditioning, I'd bet the condensation drain tube is plugged. When this happens, the excess water which collects has no where to go but into the passenger side foot well. To fix this, you need to find the drain tube which should stick down under the car on the passenger side of the engine bay (can only be accessed from below). When ...

In my travels, I haven't seen an aftermarket water pump listed for both the N52 and N54 engines. There are N54 water pumps with stronger materials though. You may wish to try one of those. And as has been suggested by @Terry Gould, look into your warranty. Some parts do fail frequently, and the water pump on this engine is a known weakness, shop around (at ...

I believe if one (or more) of the roof drains were blocked, you'd be seeing wetness around the ceiling and pillars of the vehicle. Typically, a plugged drain in the cowell box will cause you to have water drain into the passenger foot well area. This is the area at the back of the engine bay, underneath the hood. You have to pull up the two sections of ...

Not good. The proverbial "milk shake". But... from the color I'd sooner suspect the transmission cooler is what is leaking, not engine oil from a blown headgasket. Check the transmission dipstick (if you have one) and see if has this same frothy opaque appearance. It should be red, amber, or even a dark red approaching black - but should have none of ...

I would begin to look around your windshield molding, front and back. Ensure the rubber is not dry rotted. Dry rot can occur from many heat cycles (night/day) as well as ultra violet light exposure. The spotlight mount is also a good place to check to ensure the rubber mount is nicely sealed against the body of the car. If water can into the body, during ...

Since that brake booster is very vital in the function of your brakes, I would HIGHLY suggest just replacing it; You could even get one from a junkyard depending on the year. Once you get water into the brake booster, depending on the quality and coatings of the metal used; You can possibly rot the diaphragm or rust out the inside. I just recently worked ...

A large number of people recommend sodium silicate - sold as "liquid glass in the US I believe. This is also used as an egg preservative. An excellent user discussion of sodium silicate and other materials can be found here. I'm in New Zealand. Here we have a material named "Soldrit Super Soda" which has been on the market for 40+ years (ask me how I know :-...

While it is not imperative that it is completely flush together, it will make a difference. You will have a leak possibility there. This is the reason you replaced the weather stripping in the first place. What you need to do is stretch the weather stripping down on both sides so it will come together in the middle. If you start at dead center on the top ...
