Cooling system problem - W163

[mattuk]

Driving with "low coolant" message on dash will cause it as well and because you had missing coolant without visable external leaks must go on cylinder causing cloud of smoke behind you.
Never mind head is off, crack is there so don't worry about have you or not

Is there any scrap metal place where you could sell it? Cost of shipping to UK and sell here will miss it point. How much u can get? I don't know 50,100, 200,300 euro maybe? How much it will weight?

Hi

Hello.
I would like if anyone knows anything more about the cooling system for MB ML270cdi
I have MB 270CDI I have a problem with trapped air intestines, and intestines become too hard.
Once you open the expansion tank fluid out through the cap and there is too much pressure.If look up in the expansion tank you see bubbles. Oil level is in the normal condition.When intestines become hard,and all night to rest the claim until open expansion tank.
Еngine temperature is in the normal state, because the thermostat is open all the time, try and bypass to EGR valve but not getting any results are still a bubble in the container, and intestines claims.There was no smoke in the exhaust system.Еngine works perfectly.
Please if there is someone any idea for my problem.
Thanks

If u open cap when engine hot it will blow coolant. system build pressure when engine work - normal


Do not open cap when engine hot, you might get injury.

I see do u mean hoses are hard yes?

what hose do u mean? Upper or all hoses? Can u squeeze or they are hard as rock?

Ps what mileage and what works were done in cooling system? How Long do u own this car for and when first did u notice that?

All hoses is hard like rock.Ml have 220000km.i have 1 year .And thermostat is open all timei see bubbles in thank and when hoses is hard open the cup and hosess its ok and again bubbles in expansion tank and again hard hoses.

So when u remove cap all the pressure escapes and hoses become soft - u might have air lock. Drain coolant, fill new and bleed if that won't help then we can go further but before u do that go to good garage and do sniff test (£10-20)to rule out head gasket, cracked head. If both will turn up ok then put new coolant.

Also after run can u feel lower hose and radiator how hot they are against upper hose?

After reading all your posts, it sounds to me like a head or gasket failure, the bubbles in the header tank and pressurising of the system after only a few minutes running time are all typical head gasket failure symptoms.

Its possible that the 2nd head is faulty then.

I dont think putting in a sealant will help if the pressure is as bad as you say.

Could it be worth a bottle of K38 sealer

Аnd the old head had the same symptoms.It is possible 2 heads be faliture.Same mechanics seys perhaps is motor block????When I put a new head of neutral gas has only a bubble, but when when you press the pedal gas on container have too much foam.And hoses is hard as rock.Radiator on the surface is hot, if you keep the top hose on hand you feel the air.
