The cooling radiator needs to be used to keep the oil from overheating. If the lines are plugged, the engine could be ruined.

Can radiator cap cause overheating?

If the cap is not holding pressure or if it is damaged, the engine will overheat. The automotive cooling system must be pressurised, WHY?? its because when you pressurise the fluid, the boiling point will increase.

Why is my 95 z28 v8 overheating checked heads and gaskets even the intake valves all good you even bought a new water pump but everytime you put coolant and water in the radiator its goin out the over?

Maybe a faulty thermostat or a possible block in the radiator or cooling system. Also check the fan is working and the cap is maintaining pressure.Rad. CapsIt sounds like the pressure cap ( radiator cap ) isn't holding pressure and when the coolant heats up & expands it just flows into the reservoir. Also if the thermostat is plugged or faulty you will have similar problems IE. too much pressure and overheating. Your problem sounds like both at once.

What causes overheating when radiator and thermostats checked and OK and fan OK?

There are a number of things that could cause the overheating issue. If the overheating happens immediately, it's probably the water pump. If this happens only when it's hot, see if it happens only when the AC is on because then it could be the an auxiliary AC cooling fan that has gone bad.

Can you still drive your ford ranger with no radiator lid?

Not very far. Without the cap on your radiator your cooling fluid will not flow properly and you can have a serious problem with overheating.

Why is it not safe to open the radiator cap when engine is overheating?

When the cooling system is overheated, the coolant is at pressure. Removing the radiator cap will release the pressure, and allow the coolant to boil, probably splashing you with boiling-hot radiator fluid. Your arms and hands will certainly be burned, and there's a good chance that the boiling coolant will splash your face. You wouldn't like it if that happens.
