How long can a musso 622 engine run without water


Hi Stefan:
I would not even consider trying to run the engine without coolant.
Diesel engines run hot and the engine will be ruined if run without coolant.

2002 monte carlo ls 3.4l Fill coolant reserve up when car cold. Run car till reach normal temperature. Check coolant reserve, coolant gone. No leaks, no coolant smell. Where is it going?


there is either a pocket of air or the car is burning the coolant if there is no leak. check inside the car for any coolant leaking under the dash if so the heater core has a hole in it.

Transmission fluid level need regular top up and there is no external leak.Fluid color looks white.


If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

1998 Isuzu rodeo running hot. filled radiator & reservoir with water & coolant. There is a oily substance dripping from small hose at the bottom of radiator, dont see any water leaking. Just had...


Replace small hose and clamp, that hose come's from your transmission, goes through another tank in the radiator, to keep the transmission fluid cool, hope this was very helpful.

2002 ford taurus. Radiator overflows but, temp gauge not hot.


It could be both your thermostat and water pump, it could also be an air lock in your cooling system. One way or another, I think pressure is building up in part of the system because its not circulating properly.

When its cool, take the top off your reservoir, give the bottom hose to your radiator a good few squeezes, see if the water goes down a little, if it does, you moved something on and probably cured it.

If not, run the engine up, to get it warm and bleed off any air in the system. (Assuming there are bleed taps in the system)

If that also does nothing, I reckon its your water pump. And if your changing that, I'd suggest changing the thermostat at the same time.

Radiator blockage?


The blockage seems to be in the water-body. The water-body is directly mounted on the engine. Over time rust builds up inside it blocking its pipes and corroding its fan so that the circulation ceases.
Your description indicates that the incoming pipe to the water-body is blocked.

Water not staying in Radiator


yes, not having an overflow reservoir for your radiator will cause you to lose water. As your engine warms up the water expands and creates pressure in the cooling system. When the pressure reaches a certain point(usually about 15 psi.) the radiator releives the pressure by releasing water into the overflow tank. When the engine cools back down the water shrinks pulling water back into the radiator from the overflow. If there is no overflow, the everytime the engine warms up on a drive water will be lost and not recovered on cooldown.

2000 DURAMAX WATER IN OIL, DOES NOT SMOKE,RUNS GREAT,NO SES LIGHT ON,PERFORMED PRESSURE TEST AND DID NOT LOSE PRESSURE


if u have coolant in the oil u have a leaky head gasket. no other source of this problem other than a cracked block, it is very hard to detect with a pressure test, we check by using a gas sensor in the radiator (from a smog machine), or if u are lucky u will see bubbles from the leak while it is running in the coolant tank.
