Hi All,

Having a problem withthe cooling system on my S70. The coolant tank wont stay full but I cant seem to find where any coolant is leaking around the engine.

I can refill the tank and then drive between 30 - 40 kms and then the low radiator light comes on. It isnt over heating and i can drive over 100 k's with the light on and it only appears to drop the water in the bottle and takes about 1/2 to a litre to refill.

Please Help me, its driving me insane!

Cheers

 

Do you smell coolant in the car?
The heater core might be leaking.

 

no smell of cooloant in the car, or any sign of coolant in the car. Have had the heater running to test that.

 

Then you will have to find someway to pressurize teh system and check for leaks.

 

Is it showing more white smoke than usual?

 

Coolant reservoirs and heater cores often start as small leaks
that are difficult to diagnose. If you would like you can lift
up coolant reservoir and check around hose connections for
staining. Smaller hoseconnector is weak,so be gentle.
I hope this helps

Thanks for all the ideas, found the problem.

One of the heater hoses that runs across the bottom radiator hosed a pin hole. Diddnt notice it cause the coolant was pooling on the top of the transmision and not leaking under the car. I found it when the car was parked on a funny angle and it ran off.
