Mitsubishi schematics i have a gasket that has coolant shooting out but don't know which gasket it is. what its called and how to replace it.

Likely what we call, "mousse". Oil. Typically caused by a blown head gasket.

There are "head gasket fix" treatments you can try. I don't know if they work. Replacing a head gasket can be expensive.

If you have replaced the coolant it may have trapped air..you fix this by allowing the vehicle to idle with radiator cap off and allow to get to operation temp ever so ofter squeeze the lower radiator pipe this will help move out trapped air when the thermostat opens it will draw the coolant down just add water when it does..if the thermostat doesnt open you may have a bad or stuck closed thermostat. On bad news side if the temp shoots up under acceleration and drops off to norm on deceleration you either have a blown head gasket or cracked head.

What is a "level counter"? I am not familiar with this terminology.
What colour is the smoke from your tailpipe? White: possible coolant leak/head gasket failure. Blue: Possibly running too rich or burning oil. Black: Burning oil

With the car running because it reduces the back pressure have someone that knows how to do it remove the cap from the radiator and see if the radiator is full, not the bottle but the radiator itself. If the antifreeze is not moving from the bottle to the radiator it will overheat. Not having heat unless you rev the engine makes me think the radiator is either not circulating the water or it is low.

Blocks rarely crack, heads do crack more often. Most likely you have blown a gasket. Unless you can see coolant coming from a crack , you will have to disassemble it to find out

This is a coolant tube that goes to the top of the water pump, it is called the upper water pump bypass tube, you will also need to purchase the rubber o-ring

When replacing, make sure you are doing a coolant flush, as old cooland will cause this type of corrosion and failure

good luck

Head gasket most likely.

You have several problems. Replace he coolant you lost, but look for the leak. Likewise, determine the source of the oil leak and replace the appropriate gasket/seal.

To troubleshoot the blower, you will need a voltmeter and a schematic. Measure the voltage to the blower motor with the switch in multiple positions. This will help you determine if you need a new blower switch or blower motor.

white smoke is usually a sign of coolant getting past the head gasket good call not fun fix. if you can test your system get a coolant pressure tester put it on you reservoir tank and see if the pressure rises once the car gets to operating temp if it climbs fast then yes it a head gasket
