You need to get hold of a sniff tester.Its a glass tube that you put special fluid in ,then you remove your header tank cap (when you have run your engine for a bit ) then put the tube in the tank press the ball a few times and if the fluid changer's colour then this will tell you if your head gasket has gone ,(because it detects carbon from the fuel )which is common for the rover v8's
you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.
your radiator needs to be replaced
Check the coolant fan see if it turns on when the engine gets hot. if not then your temp sensor could be bad
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
Clogged radiator, bad water pump, defective fan or fan thermal relay.
The cooling system of a BMW 318i is bled by opening the radiator cap and squeezing the upper radiator hose. This purges air from the system which can then be replaced with more coolant.
No, just replace the radiator. The other one (in the front) is the condenser for the a/c system.
There is a high probability that the system needs to be bled. As in bleed the air from the system. Just filling the system is not enough. You need to warm the engine to get the water flowing, then switch off and bleed the air out. Yes there is always some air and it gravitates to the highest point of the cooling system. I hope this helps
It means that you are either low on water or there is a problem in the radiator system hope this helps
A leak in a coolant system can usually be fixed by replacing a hose. If the leak is at the end of the hose, a new clamp might be necessary. If the radiator is leaking, the radiator might need to be replaced.
iv had a problem with the vacuum for changing the vent placing i replaced the blue rubber pad behind the vent selector and it works great ( about 20 bucks at a scrap yard
po440 is a problem on cooling system or fan in radiator
