I have a problem when i start the car in the coolant reservoir it starts boiling and the temperature goes up, I changed the thermostat, and water pump, i checked the oil and it is clean and there is no antifreeze in the oil.

How did this problem start? What was the original problem?

Was the car severely overheated in the past?

I don't know what checking the oil has to do with overheating.

You need to get all the air out of the system, preferably using a vacuum fill tool. Then see how it acts.

I have already tried that too and nothing happened, it is boiling from the reservoir maybe it is the head gasket?

It most likely is if you are positive you got all the air out.

Can you tell me why there is no antifreeze in the oil if it is the head gasket.

That almost never happens with a blown head gasket. It normally blows between cylinder compression and a cooling port forcing combustion gases into the cooling system. The head usually has to crack to get coolant in the oil.

Wo,wo,wo.............

Slow down here. You at least need to confirm that with some testing. There are a number of tests for this, some are reliable and some are not. The very most reliable is using an exhaust analyzer to sniff for hydrocarbons at the radiator filler. Another good way is to remove all the spark plugs and put pressure on the cooling system for a long time, at least a couple hours and look for any coolant getting into any of the cylinders.

There are some blue fluid chemical tests that are usually very inconclusive.
