No radiator fan, no AC, it happens when hot summer comes.

Your engine gonna blow up soon due to head gasket.as fir ac check the pressure

 

The AC is seperate from the engine cooling... Two different problems. The compressor for the AC makes noise when on so you might have a bad compressor. The cooling fan for the engine rarely needs to run so not too much of a concern as long as engine isn't running hot.

 

That's only a concern if engine temp gets high, but not a concern if it stays normal. If engine temp is normal the fan won't even turn on.

 

yeah just drive slow, if ice goes beyond 180-190, you’re still gonna blow ice up.

 

The OP did mention losing coolant, so it's possible this car has more than one issue, one involving the A/C, and a different one causing loss of coolant (such as a head gasket issue).

 

maybe with 'coolant' he means the refrigerant from the ac?

 

Possibly, only when I read "checked the coolant and it was empty" or "filled up the coolant", I tend to assume that isn't somebody's way of talking about refrigerant, or at least I hope it isn't.

 

Well, the coolant going away is a fairly serious problem (arguably more serious than an A/C issue). And it's not quite true that "fans don't really need to work" ... the car decides when they don't need to work, or need to run on low speed, or need to run on high speed. They do need to work when the car calls for them.

 

There are 2 cooling systems in the car, one for engine, the other one for the inverter.
Not sure wich one that you are referring to?

First to check is engine oil, see if any signs of water blended (milky like color),
if it does, then you probably have blown head gasket.

Then I will check the inverter coolant pump. locate the coolant reservoir that sits next to inverter.
open the lid of coolant reservoir , and turn the car on without starting engine,
(press start twice without pressing brake). Then go to check the coolant reservoir, if there's some ripple, that means
it's working fine. If not then you should getting a new coolant pump.

 

The fans should be running when you turn on the ac but not at max speed.

 

I'm glad you resolved the ac problem.
It sounds like you have a leaking head gasket.
Unless the leak is somewhere else...

 

Since the ac doesn't run off a belt, the engine isn't effected by it.
Pressure test the system and look in the cylinders for fluid, and along the coolant hoses
and pump. And don't forget about the heater core.

Since you cleaned the egr and manifold, you're running out of reasons, so a leaking head gasket
is becoming closer to the reason for the shakes...

 

The black wire connector? That’s reported here with tiresome regularity; the connector’s like a little “cup” atop the compressor, and hosing (or pressure washing, even worse) the engine bay can fill it with water, not good.

regarding the engine coolant, see “bad flywheel” link in my signature. With 400k kms, likely too late, but for (or if) next time.
