If you start the car cold and it pushes water out of the coolant reservoir,you most likely need a head gasket or have a crack somewhere in the cooling system that allows combustion pressure to enter the cooling system.Not good.

No heat

sounds like you have air in the system, take the top off the water bottle and fill to the top run engine until fans come on and up to temp. keep filling the bottle so its at the top have the heater on but on low blow or no blow squeeze the pipes wile warming up to help move the air. you should see bubbles coming out the bottle when at temp turn the engine off and leave to cool down. you may need to top up now. but dont top up with water top up with antifreeze. put top back on and it should be fine. if not repeat. also check the valve is working and not blocked on the control for water direction will be electric type or vacuum type electric type should click when it is working vacuum type it runs off the engine vacuum line look for a leak in the line. and replace if it has a leak.

Cant any one Help me my car over heats and After a few minutes i get water leak from the Deposit

sounds like you have a cracked head or a blowen head gasket, take the small black hose that is connected to the filler bottle (coming from the radiator cap) and put the end of the hose from the filler tank in a half full bottle of water make sure the end of the hose is under the water, start the engine and run for about 5 to 10 minutes, if there are bubbles coming from the hose this will tell you the head has a crack in it or you have a blowen head gasket. take it to your mechanic for repairs

I have 1998 740i BMW that is overheating. 1) What are the warning signs of a bad water pump? 2) What are the warning signs of a blown head gasket? 3) What are the warning signs of bad timing?

Timing - engine is not sounding right or back firing.
Head gasket - water and oil mixing, see inside water bottle. or open bottle. rev engine when cold, if starts spitting water out while cold like a fountain.
Water pump - Water leaking from side of engine. or when car started and water bottle is open and no circulation is visible could be signs of water pump
Remember - Block radiator lines can also cause over heating problems and lack of water circulation.

Water comes out of the over flow bottle(i checked the cap)

make sure you dont over fill the radiator bottle past max, something else to try is run the system with out the cap on for a few minutes at idle to expel any air pockets in your cooling system.

I have a 1999 Porsche 911 it overheats on side street but not on the freeway. All radiator fan works including engine fan. Any suggestion?

air pockets develop over time and what most people do not realise is that the cooling system of the car loses water through damp over time. when there is not enough water in the cooling system it pushes air through which rapidly heats up. on the highway higher speeds cool things down. but lower speeds not. open the waterbottle cap when the car is totally cooled off. not hot. never when its hot. this will create more air pockets in the cooling system. open the bottle cap and fill it up full. start the engine and add water. if you car has an aircon switch it on to full. this will push air pocket out off your cooling system. as bubbles blow out keep on filling water until cooling system is bled. good luck

Why is the coolant coming out of the overflow bottle

make sure there is no coolant leak. is the radiator fan running? it should run whenever the A/C is on. if not, that will be the problem. Engine running, A/C on, see if the fan is running, if not get a long rod, broom handle ect and tap on the motor, if it starts to spin or starts running, replace the fan assy.

Water come out from Water line when Engine Shutdown.

Does it show signs of over heating at all? When cool, take off rad cap & check level in rad & top it up. If down a lot, start engine, turn on heat & let run until you hear rad fan come on & check temperature gauge to see if normal operating temperature. Let it come on a couple of times, and top up rad an inch or so from top, then put rad cap back on. Top up bottle to proper level & try it. If it spits back into return bottle, try replacing rad cap.

How to replace thermostat on

Do this when cool. Take radiator cap off, start the engine, turn on heat (not defrost) and now top up coolant to about an inch or 2 from top of radiator, as level drops down, and let vehicle run until the radiator fan comes on, then off, about 3 times, and add coolant as needed while it's running. After that, put radiator cap back on tight & make sure return bottle is filled to proper level. Now try that & see how heat is, temperature gauge etc, and keep an eye on return bottle level for a while. Let me know how it is.
