Takes a special tool to remove the line. Any parts store should have this, cheap.

SOURCE: I have a leak on

If it's a small leak, wait til the radiator is cold and you can seal the outside of it with JB Weld or another temperature-capable epoxy. If it's cracked badly, you'll need a new radiator.

SOURCE: Transmission fluid leak just off Radiator

Those are your transmission cooling lines. Buy them and replace them.

When you install them, take your time...don't be in a rush.

SOURCE: my 2002 chevy impala is leaking transmission fluid

The line could need to be tightened. Tighten it with a 1/2" line wrench.(I think thats the right size for your car) Then check the trans fluid level to be sure its at the right level.

Transmission fluid & radiator fluid keeps getting low. know approx. where leak is, drivers side front on inside of front tire. would a leak in radiator cause trans. fluid to leak also from radiator?...

Your transmission fluid runs to your cooling system to cool the transmission oil. So, in answer to your question, one of the two transmission lines (one in, bottom and one out, top) could be leaking from the cooling system.

Bring your vehicle in for a cooling system pressure check. Another thing to keep in mind when inspecting leaks is that where you see the leak may not necessarily be where the leak is from. While the leak will drip down, the wind from when you're driving will splatter the leak all over the under-carriage of your vehicle making it look like leaks are happening where they in fact, are not.

99 suburban leaking from oil cooler fitting on radiator

It sounds like you might have a crack in the plastic tank of the radiator. If the line was leaking, I would think you'd see some oil leaking. Any anti-freeze leaking? When the truck is cooled down, I'd check the anti-freeze and oil level.

Oil leak after radiator change

The radiator has a transmission and engine oil cooler lines to it too. One of the oil lines are leaking, if you know which one that's have the battle. I believe the transmission line is on the passenger sides and the oil cooler line is on the drivers side. Look at where the lines connect to the radiator and see if there is signs of the leak. You may need to spray it down with brake cleaner if you not sure if it's a new leak or old leak from the accident. Good luck and hope this helps. And what do you mean by rear case gasket?? You mean the gasket that connects the transmission to the transfer case, or the rear O ring yoke gasket.

Oil leaks can come from any where. Search for information on tracer dyes on-line. If its from the radiator area and the oil appears red its transmission oil. In most cars there is an area in the radiator for cooling the transmission oil. Try replacing tightning but not over-tightning the clamps in the two small hoses connected to the radiator.
