Radiators

Yes, It's very tricky and takes time to do it. Process called Thermo Welding. There is many DIY guide on the Internet. basic 101 about thermo welding...

You have two options.

1st option is to buy professional plastic welder kit (starts $50-$300) that will melt plastic parts and fuse it back as one new solid part.
how does it work!
Simple you heat whole area where plastic welding will place, then once you reached required temperature for the plastic that you weld, use your plastic welding gun and the plastic ROD (ROD is new material that will be added to the welding process)
BTW very important you can only weld SAME type of plastic together, mixing it with other types of plastic may cause bad results.

Once you have both radiator and new ROD heated they will slowly join them self.

This is not easy but works,

2nd option: instead buying plastic welder you can try to use adjustable temperature or none adjustable soldering iron. On none adjustable soldering iron you have to play with the distance of the tip so you always have same temperatures on the part's it's very important to reach correct temperature for this to get successful results.

I hope this little info will help.

Rust, most likely.

Usualy anodised iron, a Spring, and neoprene.

A radiator has no moving parts. It's only job is to dissipate the heat of combustion in your engine. If it doesn't do that job, it's bad. One of the most insidious faults a radiator can have is rust and corrosion build up inside the radiator. This keeps the fluid from circulating. Many times, this cannot be seen. A corroded radiator is a bad radiator. A leaky radiator is a bad radiator; it can't hold the fluid. A radiator with a majority of the cooling fins bent so that air can't pass through is a bad radiator; it can't cool the fluid. One of the tests they do on radiators is to pump them up with air and listen for whistling leaks. Sometimes, they submerge them in a bath to see if any bubbles form, and if they form, where they're coming from. If bubbles do form, it is a bad radiator.

Ours just ripped open on the highway. Do not try to repair, as it will rip again at the wrong time.

The basic rule of thermodynamics is that heat goes from where it's hot to where it's not. The coolant in a vehicle takes (draws or sinks) heat from the engine, and this heats the coolant. The hot coolant carries off the heat, and then flows through the radiator. Air passing the elements of the radiator, because it is cooler, takes (again, draws or sinks) heat from the radiator's fins, which transfer the heat of the coolant out. The hot coolant loses heat energy as it flows through the radiator, and heat from that coolant is passing through the metal radiator elements into the air flowing past. The radiator sets up a relatively large surface area to that passing air so that "a lot" of heat transfer can take place. There is what is called a thermal gradient across the elements in the radiator. Hot coolant inside and relatively cool air outside those elements set the ends of the gradient. Heat goes from where it is hot, the coolant, to where is it not, the air. If you guessed that there must also be a thermal gradient across the metal of the engine between the combustion chambers and the coolant chanels in the block and head, you'd be right. That thermal gradient drives heat out of the cylinder walls and head into the coolant in the coolant channels. It's just that simple. Remember that any time a temperature differetial exists, a thermal gradient exists. A thermal gradient is the "force" of heat transfer in the science of thermodynamics. Easy as pie.

For a Sedan (Car) approx 3 Gallons, for a truck or Suv, 5 gallons, it varies slightly depending on the size of the engine, (4 cylinder less, a V8 more), to know the exact amount check your users manual, or contact the Manafacture.

yes

Sounds like you got a leak - need repair

if you haven't already go to your nearest auto parts store and find a chilton manual for your vehicle.

Keep it in there, you will need it.

Yes.

Early beetles (original - not new beetles) are air cooled - they have a large fan, big cooling fins on the cylinders and a ducting system ("tin" to vw nerds) that direct air around the cylinders to cool the engine. Also an oil cooler ( a mini radiator within part of the tin duct system) that the oil circulates thru.

i want to know this aswell >.<

If your car has an oil cooler that's part of the radiator then the most probable reason would be that it's sprung a leak there. You may also have a blown head gasket, which is something that also can open up a connection between coolant flow and oil flow.

Not for very long, the coolant will splash out to a point where it will overheat.

between $400 and 600 bucks depends on type of vehicle.

The head gasket could be leaking between water jackets and the cylinders. No visible cracks would be seen as they would be internal within the gasketing material. James

It is more that likely the coolant temp sensor, Its really easy to change (if you have some mechanicalness) i would go to the dealership and buy the sensor, they're not to much maybe $20. These sensors are known for cracking. The sensor is on the head if i remember right, right above where the transmission bolts to the engine, I think you need a 10mm deepwell socket. I think you have to take off a couple other simple things to get to it. when you take it out coolant will start coming out, so unless you want to change your coolant to put it in really quick. and there ya go. Also maybe test you fan just to make sure, All you need to do is put 12volts to it with some wires.

A normal temperature reading for a vehicle would be between 180-192 degrees F. Temps of 200 and higher can damage an engine.

There is a product that you can buy and add to your radiator called STOP LEAK. Add this product according to the instructions. Be careful, this product can also clog up your radiator if not used properly.

there is an important message that says refer to service manual and i only have an owners manual in there it says for 4.7 see dealer.. any answers? ** You can get a service manual from an auto parts store. Or you can try your local library for this manual. You should follow the service manual instructions for this type vehicle to prevent engine damage. You can also try to call various mechanics in your area for best advise.

Remove radiator lower hose from radiator

connection and allow coolant to drain into a

suitable splash tray.
