Which nipple on the radiator does the hose from coolant bottle go to?

Flush coolant system again. Do you have a brown sludge in the oil. Do this get Preston coolant flush, drain radiator drain coolant tank, fill radiator with water, add the Preston run vehicle for about 15 min remove lower radiator hose from radiator. This will allow all residue to be removed from engine. Replace radiator hose. Fill radiator with appropriate amount of coolant. Disconnect tank from system and let water run through tank until it is clear. Reconnect tank and you should be good. Unless you have oil and coolant mixed which means a blown head gasket or cracked block

This is a post on the Dakota forums:
My 2001 Durango and 2002 Dakota they use the same radiator. You'll have the same setup. I have recent and intimate knowledge of draining them. Crawl under the left front of the truck and look up at the bottom of the radiator. At the bottom of the driver side radiator tank (facing toward the fender) is a 3/4" long flat handled plug. Twist your hand (with a pair of pliers) up there from the back side of the bumper fascia. Grip it and give it a 180* counterclockwise twist. It is now opened and draining out the little nipple sticking straight down from the bottom of the side tank. You can stick a 5/16" (or 3/8") hose onto the nipple to drain it into a bottle or pan without making a mess.

need to bleed the air out of the cooling system. possibly what the nipple was for.

Yes you can do it yourself

Degas Bottle Removal

1. Drain radiator (8005) until engine coolant is out of degas bottle. Disconnect radiator overflow hose (8075) and engine coolant vent hose at degas bottle.
   

1. Remove power steering oil reservoir retaining screws and position power steering oil reservoir (3A697) out of the way.
   

1. Remove degas bottle return hose and clamp. Remove degas bottle retainers and remove degas bottle.
   

Installation

1. Position degas bottle in vehicle and install retaining screw and nut. Tighten retaining bolt and nut to 9-12 Nm (80-106 lb-in).
   

1. Connect degas bottle hose and clamp to degas bottle.
   

1. Position power steering oil reservoir onto degas bottle and install retaining screws securely.
   

1. Connect radiator overflow hose and engine coolant vent hose to degas bottle.
   

1. Fill and bleed engine cooling system as described. Check for coolant leaks and proper engine coolant level after engine reaches normal operating temperature.

Hope this helps.

If there is no hose going from the radiator to the Fill/Over Fill bottle it connects to the system at a small nipple at the radiator Cap. If that nipple is missing you have a problem because to my knowledge there is no repair for this, you would end up replacing the radiator to get one. This all assumes the Radiator cap is on top of the Radiator itself. I'm not sure if Chevy used a different style where the Radiator cap was actually located at a point some where on one of the lines going to the heater core, Plymouth did this on some models.

I had a 1995 Voyager, as I recall, one is for the coolant overflow bottle, and the other was plugged and did not connect to anything.

The "smoke" you saw was your coolant. The vehicle uses engine coolant piped into the cabin of the car and through a little radiator under the dash for the heater. The blower in your car forces air over this radiator and this heated air is what you feel at the vents.
If you're lucky then one of the hoses has sprung a leak. This is a relatively uncomplicated cheap fix. The other thing that could have happened is that the cabinheater radiator has sprung a leak. If the leak is serious then the heater radiator will need to come out for repair or replacement.
You could try running some radiator stop leak(I've used Wynn's before) through the system and see if it helps. If the leak is on the radiator it might just work. On the pipes it will not be successful. Buy a bottle at your local spare shop/Autozone. Put it in the cooling system(do not open a cooling system with the vehicle hot!) and let the vehicle idle for a while. (Read instructions on the bottle) If it does not work, have the heater radiator removed and repaired.

I think there should be a nipple there to put the hose from the overflow bottle?

Removal

CAUTION: Do not mix Standard (green) Coolant with Extended Life Coolant (orange). If mixing occurs, drain engine cooling system and refill with originally equipped coolant type. If this contamination occurs, the service change interval on Extended Life Coolant will be reduced from 6 years/150,000 miles to 3 years/30,000 miles.

1. Drain radiator until engine coolant is out of degas bottle. Disconnect radiator overflow hose and engine coolant vent hose at degas bottle.
2. Remove power steering oil reservoir retaining screws and position power steering oil reservoir out of the way.
3. Remove degas bottle return hose and clamp. Remove degas bottle retainers and remove degas bottle.

Installation

1. Position degas bottle in vehicle and install retaining screw and nut. Tighten retaining bolt and nut to 9-12 Nm (80-106 inch lbs.)
2. Connect degas bottle hose and clamp to degas bottle.
3. Position power steering oil reservoir onto degas bottle and install retaining screws securely.
4. Connect radiator overflow hose and engine coolant vent hose to degas bottle.

is it on the coolant bottle or the radiator?

on your post . you said radiator but on the thread topic, you pick coolant bottle.

anyway, if its the radiator, there are two big hose connected, one at the top and one at the bottom . then tehre is another small hose that is usually at the top where you put the radiator cap and this is the one going to the coolant bottle.

if your talking about the coolant bottle, there is one hose connected to the top where you put the radiator cap and the other one on the cover as an overflow hose.

it could be just open or another hose connected to it just to direct the water downwards. but it is not connected to anything.

i hope i answer your inquiry.

tnx 4 using fixya,
