After replacing radiator hose do you put coolant in the radiator and the overflow bottle or just the bottle?

With the engine cold, put it in the radiator just to be sure there is no air gap. Run it for a short time until it gets warm and coolant begins to circulate. Then install the radiator cap and put coolant in the overflow to the coolant level line.


How do you do a radiator flush on a 1995 Saturn?

The radiator on a 1995 Saturn is flushed by draining the coolant, refilling the engine with water, and adding a flush. It is allowed to circulate and drain before refilling with coolant.


How can you tell when the thermostat has opened?

The upper radiator hose gets hot do to the fact the coolant has started to circulate.


Does water in the reservoir circulate through radiator when engine runs?

No. When the engine is running coolant is heated and expands. Excess coolant then flows from the radiator to the expansion (overflow) tank. When the engine is shut down coolant cools and contracts drawing fluid back out of the tank to keep the radiator topped off.


What direction does a car radiator circulate?

In general the hot coolant enters the top opening and out the lower to the water pump.


What is the water pump used for in a car?

To circulate coolant through the engine block, radiator and passenger compartment heater core.


What are the major components of the automotive cooling systems?

Radiator-- for storing and removing heat from the coolant. Pump-- used to circulate coolant throughout the engine and back to the radiator for cooling. Fan, either electric or mechanical -- used to draw air through the radiator thus removing heat. Thermostat--Used to keep the coolant at a set temperature. Radiator pressure cap--Used to keep the pressure at a set amount in the system. Hoses uses to transfer coolant from the radiator to the engine and back. Recovery tank--Used to catch any coolant that may overflow.


What is a oil coolant hose?

An oil coolant?æ hose is a tube or pipe that allows engine oil to circulate via the radiator in order to cool down. Without an oil coolant hose, oil will get to hot to operate efficiently.


Why would a 2003 Pontiac grand am overheat when a new thermostat was put in and the fans work?

Low Coolant level? Perhaps cooling system is airbound not allowng coolant to circulate? Water pump defective not circulating coolant? Radiator plugged or restricted? Hoses collapsing under pressure? Defective radiator cap?


Why does Radiator run hot in 2002 Cavalier?

1. Check coolant level 2. Check to see if you have heat in the cabin 3. Feel the hoses and see if you feel any coolant passing thru them. Be careful the hoses can be hot. 4. Your thermostat may be stuck not allowing coolant to circulate 5. Your water pump has quit and will not circulate the coolant even with a good thermostat.


How do flush radiator in 1999 cougar?

The radiator on a 1999 Mercury Cougar is flushed by draining the radiator, filling it with water, and adding a commercially available radiator flush. The engine is allowed to circulate for 10 minutes, drained, flushed with fresh water, and refilled with coolant.


What would cause no circulation in radiator?

If the temp gauge reads normal and the engine is not overheating, the thermostat is doing its job. The thermostat maintains the coolant temp by opening and closing allowing the coolant to flow or not to flow. When it is closed the coolant doesn't circulate.


What is the proper procedure for filling the coolant system on a 1994 Chevy Camaro 3.4L?

This is difficult so pay attention- (1) Remove the radiator cap (2) Start filling the radiator with a proper mixture of water and coolant(Most climates us a 50/50 mixture) (3) Once the coolant reaches the radiator neck stop filling and let the coolant go down, you can speed this up by starting the engine and letting the coolant start to circulate. (4) keep doing this until the coolant level remains at or near the top of the radiator. Happy Motoring!


Is it safe to run vehicle with a bad thermostat?

A "bad" thermostat is probably one that is sticking. If it sticks open, the engine coolant will circulate through the radiator at all tiimes, making the car hard to warm up in the winter, and slightly less efficient according to the laws of heat engines. If the thermostat is stuck closed, the coolant will never circulate through the radiator, which could cause the engine to be damaged by overheating.


What is a radiotor used for in a car?

The radiator is used to cool down the coolant (water plus antifreeze etc) which in turn is used to circulate the engine and prevent it overheating.


Do radiators have two hoses?

Most have input and output hose do coolant can enter and circulate through radiator and then be returned to the engine. Automatic transmission also has 2 smaller lines running to and from the radiator to the transmission for cooling purposes


What part of the engine will coolant boil first?

The cylinder head The cylinder head area is the area where coolant will boil first if coolant is present. The area directly above the combustion chamber will get hot first, which is the bottom area of the cylinder head. The old saying that heat rises is still true. Heated coolant will usually exit the upper radiator hose to the radiator and as coolant is cooled in the radiator, it will circulate down into the block where it will be heated again to repeat the cycle. The coolant pump present in most engines just helps this natural cycle.


Where is the radiator drain valve for 1999 Ford Escort LX?

Doesnt have one, you have to remove the bottom hose to drain coolant.


Where is radiator cap located on a 1999 Oldsmobile alero?

not all vehicles have a rdiator cap. some newer ones ,have the coolant added thru the overflow bottle. if the radiator cap cannot be seen on the radiator it doesnt have one


Where does the coolant go?

Coolant goes in the radiator or you can also fill the radiator resevoir.


HOW TO DRAIN and refill COOLANT from a system which doesn't have radiator cap Would the coolant reach the radiator is we refill the coolant through the coolant header tank?

In systems that do not have a radiator cap, the coolant is drained by the radiator drain plug. It is filled by adding coolant to the system through the overflow bottle.


How do you fix the heat not working in a 2006 ford explorer?

Check to see if the engine coolant is full. Check to make sure that the engine is not running hot. The coolant circulates through the heater core, and if its not cooling the radiator it will not be able circulate to heat the vehicle


Is the water reservior just for water or for coolant for the radiator?

Radiator coolant.


Why doesnt the heater on your 1999 Chevrolet suburban work?

Could be: Low coolant in the radiator - or - thermostat stuck open - or - heater core plugged.


On a 1992 ford f250 why would the coolant back up into the overflow container and stay in the radiator?

if the coolant backs up and does not circulate, either the water pump and/or the thermostat need replacing i would check the pump first as the thermostat does not prevent circulation, just doesnt allow proper operating temp the water pump on powerstroke is an easy replacement job for a handyman but remember the bolt sizes are metric. i think they are 8 mill bolts
