Question about 1993 Mercedes-Benz Mercedes Benz 400 Class

1 Answer

Coolant overflow The 400e seems to over flow the coolant reservoir after operating the vehicle for a while and then leting it idle for several minutes. It will drip coolant out from under the cap, spilling out about 10 to 30 ounces of antifreeze. After the car sits it runs fine and stays normal temperature.

Why does my heater blow cold at idle


  1. You May perform the following with the vehicle in park or neutral with emergency brake firmly on.
  2. Check the coolant level when the engine is cold. With proper coolant, fill radiator to top and reservoir to the COLD LEVEL mark.
  3. With radiator cap off, start the engine and let it idle.
  4. After 10 minutes of running at idle, you should observe a coolant flow in the radiator.
  5. if you observe flow, reach inside car and turn on the heater to high and max temp.
  6. Now observe the radiator fill level. If the level has dropped substantially, add more coolant to the system to the top. the coolant should be warm or even HOT. If it fails this observation go to #8
  7. If so, replace the caps on your system. Take the vehicle for a short drive and check your heat at an idle inside the car. It should be normal if you have made all the above observations.
  8. If coolant remains cool or cold, it is likely a faulty component. A bad thermostat will cause this symptom. Faulty servos or valves that control the flow of air in the cab.
  9. There could still be air in the system. Some systems are actually higher on the engine components than the filling points and have to have the air bled off.
  10. You may consider a qualified service Mechanic to make the repairs.

Tip

Basic checks:- if your vehicle is overheating.


The below checks are generally intended to apply to any make of motor vehicle, (even though, to post this tip I had to select a particular make & model).

Overheating may be caused by many things.
Ensure engine tune or other mechanical disfunction is not contributing to the overheat problem.
Ensure there are no vacuum leaks on the engine air induction system.
If gas bubbles are apparent in the coolant reservoir when the engine is running the motor it may have a blown headgasket - (if confirmation is required, go to a radiator shop and request a "combustion gas detector" test).

If no obvious mechanical problems exist I suggest you carry out the following checks:-
1) Check coolant system is not leaking fluid due cracked/perished hose or hose fitting, leaking water pump etc,
2) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
3) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
4) Check coolant reservoir pressure cap is serviceable,
5) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow.
7) Check or replace the thermostat.

Engine or hydraulic system overheating clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

]clearpix.gif//-->
Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

My Chevy Venture 1999 when I drived the temperature was normally, but when I stay the temperature was hot. I changed the termosthator but the problem is continually.


Check the coolant reservoir and the radiator for proper coolant level. If low you probably have a leaking intake gasket or possibly a head gasket leak. The intake leak will be visible on either end of the intake manifold, located at the very top portion of the engine. The head gasket usually shows up at the rear head, nearest the belt. You could have a water pump leaking and this would show coolant on the ground under the right front of the engine, more so when the engine is running. They are very common for all 3 problems.

Losing coolant from the reservoir but cannot see any coolant leaking on drive. Fill reservior to MAX and within ~10miles, reservoir is drained. Refill while engine still hot and don't lose nearly as much...


my '01 Jetta had a similar problem. I could always smell coolant and the bottle was always low. I crawled under the car and there it was..a caked on mess of pink antifreeze. There is a plastic intersection 3 way valve where the coolant temp sensor resides. it has 2 bolts and a rubber o-ring. Because it is plastic, it cracks. it drips down onto areas which are really not visible from above and then sizzles and melts onto areas under the engine. The part was only about $25, took 30 min to install and my problem is now fixed. Air was getting into the system through the small crack in the valve further complicating the system operation.

Removal of the thermostat from the cooling system is not a good idea. This upsets the coolant flow rate in the system, and that can cause the engine to overheat, even when no other problem with the cooling system exists.

Try to identify the cause of the overheating.

Ensure that engine tune, or other engine mechanical fault condition is not the cause of the overheating, then go through the checklist following:-

1) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
2) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
3) Check coolant reservoir pressure cap is serviceable,
4) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
5) Check for combustion gas bubbles in the coolant reservoir while the motor is running - this indicates a blown head gasket. If in doubt, take it to a radiator shop and ask for a combustion gas check on your radiator.
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

If all above ok, replace the thermostat again (also ensure it is not installed upside down) - faulty new thermostats are not unheard of.

Where do i refill coolant? message reading low engine coolant.


please rate, thx Coolant Recovery System NOTE: When the water thermostat (8575) is closed, there is no flow through the radiator coolant recovery reservoir (8A080).

Trapped air in the cooling system must be removed. A pressurized radiator coolant recovery reservoir system is used which continuously separates the air from the cooling system.
  • When the water thermostat is open, coolant flows through the small hose from the top of the radiator outlet tank to the radiator coolant recovery reservoir.
  • The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose to the water thermostat housing.
  • The radiator coolant recovery reservoir serves as the location for:
    • service fill
    • coolant expansion during warm-up
    • system pressurization from the pressure relief cap and
    • air separation during operation
  • The radiator coolant recovery reservoir is designed to have approximately 0.5-1 liter (0.53-1.06 quarts) of air when cold to allow for coolant expansion.

Hello there.....

First things first: Is the temperature gauge showing normal as it is supposed to be? No contamination of oil & water on withdrawing the oil dipstick? Head gasket not the culprit here? No excessive steam on idling from the exhaust system? If these signs are not present than I suppose there could be an air lock within the cooling system - bleed the system - check if the radiator/coolant reservoir cap is satisfactory. Top up the radiator (if possible) with mixture of water & antifreeze whilst the vehicle is idling. Hope this helps.

Good luck
