Turn on the heat in the car to full heat an full fan. Remove radiator cap start car and continue to fill overflow bottle/tank until heater starts to blow warm that's when the thermostat begins to open. Keep an eye on matter level -make sure it's full. Replace cap a wait 6/7minutes open cap slowly and with rag and gloves it will be hot. Slowly -continue to add more water. Until full. Replace cap. Shut off motor and wait until it cools about 45 minutes. Remove cap again and add water as needed. Then run
Motor making sure it is full. One more thing most important anytime filling radiator always turn heat on first. If not you will ruin your radiator as they don't swell open they swell closed as to not let water move thru it's internal passages.

My 2000 SL2 is still overheating after all has been replaced i.e. water pump, radiator, I took the thermostat out (but when the cars is running, there isn't a good flow of water) the head gasket too.

Did you flush the system out before installing the new water pump? Scale may have loosened up and blocked some flow. Reverse flush the engine, radiator and heater core. Removing the thermostat for testing is ok, but don't plan to run it like that. It may actually run hotter without the thermostat.

Overheating and not starting when warm

Accoriding to the Haynes manual for your vehicle there a possiblily of several grips.
ENGINE HARD TO START WHEN WARM: 1. airfilter clogged, 2. fuel not reaching fuel injection system, 3. corroded battery connections, especially ground.
OVERHEATING: 1, insufficent cooland in system, 2. waterpump drivebelt defective or out of adjustment, 3. Radiator core blocked or grille restricted, 4. thermostat faulty. 5. Electric coolant fan blades broken or cracked, 6. coolant cap not maintaining proper pressure.
Hope this helps!

Have no heat. Have replaced heater core,

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!
