It's a line that feeds transmission fluid up to the radiator. Most automatics have radiators that also incorporate a transmission cooler (heat is the #1 killer of auto transmissions). That line allows the fluid to move to the radiator for cooling.

I have a 2001 mercury grand marquis ls. it overheats when im driving it but don't shows it on the temperature hand ..what is the problem ??

The temperature switch on the side of the upper radiator hose is not working. That is, if the engine is hot. Boiling over - need to check thermostat. Grab on to upper hose (should be hot) than with engine off, grab bottom radiator hose. It also should be same temperature as top. If so, thermostat ok. Electric radiator fan - turn Ac on. Fans should run. No, check fuses & relay. Mechanical fan - with engine off, the blade should be stiff to turn. Easy, replace fan clutch. Usually, low level of water is most common. Wish you well.

Radiator hose is swelled up

A radiator hose that swelled up is caused by the hose breaking down, we call this a "soft hose" and it must be replaced ASAP. As far as the high idle goes this is caused either by an engine vacuum leak or a defective automatic idle speed control valve. You need to have the dealer run some basic testing with a tool called a scanner to see what is going on.

  • Lower radiator hose.

Where is the radiator bolt located, to drain the water out of the radiator

should be at the bottom of the rad with a little hose coming from it .(the hose points down and goes nowhere just ther to help drain) if you cant find it you can also pull the bottom rad hose off and drain it that way.

Looking for hose that goes from reservoir to engine, is it only a dealer part and what is it called

Your overflow reservoir is available on ebay, but if all you need is the hose, just buy a piece of hose, it is nothing special, probably why it isn't listed as a part, just like an O-ring, they are shelf items, match up the hose diameter and the length, clamp it on, you should be all set. Hope this helps.
