Wont hold water. big hose on the bottom of the radiator attaches 2 the engine and it leaks right out of the engine underneath that hose...

totally depends on year make and model. Let me know and I could help

Yes, you can do it! First, just check if the clamp on the end of the hose where it connects to radiator is just loose and needs tightening. That may be all it needs to stop the leak. When your new radiator was installed, sometimes the clamp may not have been tightened enough. If the clamp is just like a wire clamp and can't be tightened, buy a good screw clamp and fit it on. If that is not the case, you may need to pull off the lower radiator hose to investigate. Of course, to remove hose, you need to drain the radiator first. The other end of the hose goes to an inlet fitting to the water pump on the front of the engine. It will also have a clamp that you loosen or remove to pull hose off that fitting.
How it works is hot coolant in the engine is pushed by the water pump into the upper radiator hose and goes down through the radiator for cooling it and then back into the engine through the bottom radiator hose. The water pump constantly circulates the coolant through the engine to the radiator and back into the engine through the lower radiator hose.
I would bet you just have a loose fitting hose. See if you can tighten it first.

I think you are referring to the radiator hose,there is one at the bottom of the radiator & one at the top, you just ask for a top or bottom radiator hose( whichever one is leaking) for you make & model vehicle.....hope this helps......cheers.

look in engine compartment from underneath- if water coming from directly over crank pulley(big one closest to ground) ,yes its the water pump- could also be lower hose(radiator hose closest to ground),if leaking up top - could be other radiator hose- if leaking near fire wall- heater hose- ?where is the water appearing?

It should be at the front of the engine where the upper radiator hose is attached to the engine. The radiator hose will be attached to the thermostat housing with a hose clamp. The thermostat housing should have two bolts holding it in place. Remove the gbolts(engine cold) and raise the housing up, The thermostat will be underneath. Make sure the new thermostat is facing the right way when you install it, Don't forget the gasket. Bolt the housing back in place and install the radiator hose and clamp. Replenish any coolant that was lost to bring the coolant level back up. Run the engine long enough for it to warm up. Check for leaks, monitor the temperature guage to make sure it reaches normal temp without overhearing, and make sure the heater is blowing warm air.

follow top radiator hose to engine where hose stops thats where the tstats at.

There is a radiator hose attachment on the engine where the radiator hose from the top of the radiator attaches to the engine. After you drain the radiator, remove the radiator hose from the engine and then remove the nuts holding the hose attachment to the engine you will find the thermostat sitting right there controlling the water flow.

you are looking at a water pump problem, have fun

Hi sir, if you want to do a proper job here's how.

1. Get radiator flush let you car Idle for a while or drive for 15 min.
2. Let Car cool Down
3. If no drain PLug remove the hose at the bottom this is the same pipe going into your water pump, Work gentle with it try not to damage the pipe.
4. open your rediator cap, this will allow the water to train from radiator.

What about all the dirty water inside the engine? this is how to do a decent flush.

• The car should be cold
• remove the water pipe at the top of the radiator
• take your garden hose and insert it to the rediator don't force it just hold it there.
• Start the car let it idle, open the hose pipe.

What happens now is that the water pump pulls all the clean water trough the rediator and pushes all the dirty water out the other side.

• when water is clear turn off water
• kill engine
• Tighten water hose
• refill with good Anti freeze anti boil and top op with water
• drive the car till hot
• check for any leaks on the pipes you removed before

Hope this Helps

First, Is there actually coolant in the over flow tank?

If the bottle is full the coolant level sensor may be bad. The sensor pulls out the bottom of the overflow reservior.

If the bottle gets low overnight there is a leak. Check the radiator side tanks for leaks. You need to look from underneath the car at the joint where the radiator meets the black tanks on the left and right sides.

You also need to look from underneath for most of the other hoses on the car, the car is turbo most likely and there are hoses that go to and from the turbos, into the cabin, and to and from the engine.
Leaks are hard to find from just looking from the top of the engine.

Hope this helps.
