Usually once a radaitor starts leaking you should replace it since it is a pressurized system and could cause overheating.

Is the plastic part of the radiator? The radiator builds pressure so sealer may only work temporarily at best. Or are you talking about the (yellow) plastic surge tank that also holds coolant? SOME of these are also under pressure.

If you need to drive somewhere and your seal fails, you will get stuck, and it might also damage your engine.

Get a new radiator or surge tank or weld your plastic (yes, plastic can be welded!) if you care about getting stuck.

Hope this helps.

SOURCE: coolant leak --redoing my former question---!

I think you are trying to say that the plastic side tank is leaking. Likely on the seam where it joins the metal part of the radiator? I haven't seen too many sealers that work on those, but the old "standby" two tablespoons of black pepper (no kidding) sometimes will, unless the leak is a large one. There are some sealers on the market that claim they can plug just about any leak, but I have never tried them. (just too many)
The best way to do that repair is by changing the radiator, either with one from a scrapyard or new.
I used pepper in my own two years ago and am still waiting for it to begin leaking. (and heat works fine) Just make sure to drive five or ten miles after adding it or it will clump up and not help at all.

Good luck..

My coolant level is dropping about two cup fulls every couple of months,there is no coolant on ground just a small water drip on garage floor after about middleways underneath engine after driving it.

There are only a few ways coolant can get out of the cooling system.
First check where the hoses connect to the radiator to make sure they are completely dry. Then check directly under radiator to make sure it isn't damp. Sometimes the radiator cap will go bad and allow some coolant to leave. You can replace the radiator cap relatively cheap. The very worst way you can be loosing coolant is thru a blown head gasket. The coolant slowly leaks into the cylinder and is burned. You would have to go to a mechanic to have this verified.

I have a radiator leak on the bottom of the radiator of my 2000 Chevrolet z71 1500. I don't know where it is coming from exactly. It is a so drip and I can see green coolant on the ground.

Coolant leaks can sometimes be difficult to locate the exact origin of the leak. That is why proffessional technicians use pressure testers, bright flashlights, inspection mirrors, and in some cases even borescopes to locate the cause.

With that said, I would say that if you have a "radiator leak" and it is "on the bottom of [your] radiator" my first guess is that it is coming from the radiator itself....check the area of the radiator where the plastic tanks are crimped to the cooling tubes (main radiator core). Sometimes the fittings in the tanks leak where the transmission cooler lines connect.

I have also seen leaking radiator caps misdiagnosed for a leaking radiator....Sometimes they will leak and the antifreeze will run along the sides of the radiator and "mimick" a radiator tank leak. Remember, the coolant almost always travels DOWN and REARWARD. Sometimes it goes way to the left or the right, but it still goes down and back from there.

A bright flashlight and an inspection mirror will verify most leaks. You may also want to detach the fan shroud and move it back for better inspection of the radiator. - start where you can see the coolant and follow the trail upward....

Rubber type plug ( passenger side of radiator) on bottom is dripping; gauge on instrument panel will show hot temperture quickley; even after adding coolant; name the plug and how to replace

That is your radiator plug. You take it out to drain the radiator. You just take it out and put another one in. Is your radiator fans working? It may be the radiator itself. Plus, it may be a coolant temp sensor. If it is a small leak, with full coolant, it wouldn't overheat quickly. Make sure the fans kick on. Check radiator.

I am leaking antifreeze under my blazer onto the ground but not inside the vehicle. My blazer does not overheat, my heat will work sometimes while driving but as soon as I stop or slow down it blows cold....

you need to figure out where the coolant is leaking from. Some common areas are

the water pump in which case you would be able to remove the splash shield from under the front of the vehicle and using a flash light be able to see coolant coming out of the weep hole of the water pump.

The intake gaskets. Look in the corner of the intake valley where the head and lower intake meet right under the a/c compressor. If you see coolant its leaking and needs to be replaced.

The radiator, you'll be looking for wet spots on the side tanks of the radiator. Loose upper and lower radiator hoses could also cause this.

If you can't find anything visually you'll need to bring it in and have it pressure tested.

This one is not easy to tell without seeing the car. But, a logical guess would be that the water pump is starting to go bad and is leaking intermediatly. If you can pressure check the cooling system or have it done that should give you the answer.

4.0L engines are known for radiator leaks. look at the back side of the radiator for dried coolant. It will appear as a green or yellowish film on the radiator. if you don't see anything there top it off with water and let it sit and idle (A/C off) while you watch for it to start dripping. when water starts to drip on the ground open the hood and look for where the water coming from. Then you know what needs replaced.

My radiator (1996 Ford Explorer) is leaking at the bottom. No problem with heating or cooling or running hot. Just steady drip

You can have it repaired at a radiator shop, or replaced with a new one. Are you sure it's the radiator that's leaking, sometimes it's the water pump or a hose that drips down onto the radiator. It can be difficult to locate due to air circulation of the fan and driving which spreads the leaking fluid around. I assume u top off the coolant often, since u say there are no issues w/ it overheating or running hot. If this is the case, the leak will eventually get worse, and adding coolant constantly gets expensive. Good luck, let me know what u decide to do, or if u have any other questions. Curt
