    You did have your heater on (not defrost) while running engine and adding coolant right?

    Can you see a cap to remove on your radiator itself?

Good morning;
does this critter have a radiator fill w/cap? I've run accross som large Sotrd trucks that don't.
Well, anyway, it soesn't make sense you would need to fill the radiator via the resenoir. That is only good for short pressure relief and cook down vacuum recovery of coolant. 60/40 is the mix ratio. If it hs a resevoir it should have a radiator cap.The air in system will purge itself as it starts to circulatte cioolant. turn heater off till your system is full, then on when engine reaches operating temp. then if needed top iff coolant. Leave radiator cap off while waiting for coolant to start circulating. When thermostat opens out comes the air. Then put coolant mix in reservoir to fill line. check for leaks and all hose clamps are tight and you should be set, Good luck - Ned

1999 chevy silverado heater fan only blows cold air , both coolant lines in are hot

I like that you were knowledgeable to check both coolant lines tells me you are getting hot coolant through the heater core next thing to check will be the blend door on the inside of your vehicle. The blend door is a door that switches from cold air duct to heater duct depending on what you are using at the time. If it is stuck on the cold air duct you will not get any heat sometimes these doors are vacuum actuated and sometimes they are electrically actuated most the time you are able to see the movement of the motor from inside if you don't see any movement but you hear it move chances are it is the door blend I hope this helps.

How do i change the air filter in my mercedes e-320 sedan?

Remove the air intake tubes on the left and right sides. Pull up the complete air filter housing off of the rubber mounts. Turn the air filter housing upside down and there will be 4 - T20 torx head screws on each sides. Unscrew these torx screws to gain access to the filter. Install new air filters and put housing back on in reverse order. Please remember to rate this solution. Thanks!

How to replace an engine belt on an 1995

I have two Mercedes - one is 2000 E320 Wagon; other is 1999 E320 Sedan.

I replaced the serpentine belt on my 2000 Wagon today at 92,000 miles. I found that the Motorcraft JK6-947 could be purchased on Ebay for $12.99 plus $6.20 shipping. The old belt was a Goodyear Gatorback 4060940. My 1999 sedan has a Mercedes Benz 011 997 97 92 6K2390 EM7117 Gates belt made in Spain.

Here are the details of replacing the belt.

On the 2000 E320, a 17 mm bolt just under the belt going to the tension pulley will release the belt tension when turned counterclockwise. Removal of the belt was easy after using a 17 mm deep socket wrench similar to a spark plug socket. I made turning the bolt very easy by slipping a 4' pipe over the socket wrench handle. It is advisable to put the new belt LAST on the idler pulley that contacts the belt only on the smooth side.

You do not need todisturb theButton Torx bolt in the center of the tension pully.

The 1999 E320 uses a 15 mm bolt in the CENTER of the tension pulley. Otherwise the installation is the same as the 2000 E320.

1999 Mercedes e-320 Heater (blows cold air)

Hi there,
firstly why did you replace the water pump, would i be correct in thinking that it broke, if so, when you took it out was there damage to the impellor, usually there is and these bits of debris have to be retreived. the hot air in your car comes from a heater matrix that is seperate to the main radiator the cause of your problem could be explained by loose debris blocking the heater matrix inlet, also that debris could fall back down and destroy the impellor on the new pump.
If the impellor completely broke up then it will be debris in the system this should be fixed asap to safeguard the new pump.

Heater is blowing cold air 1999 dodge stratus

A heater blowing cold air can be a few things. have all of these things check for proper operation to find the source of the problem.
1. Coolant level
2. Thermostat
3. Water Pump
4. Heater control valve
5. Make sure that the heater control doors are closing when you switch from hot to cold.
6.Last but not least if the climatic controls are electric it maybe at fault.
Good Luck
