Water levels in my S40 T4

I have recently replaced the turbo on my T4 and ever since I have had a problem with the water levels.
There seems to be a slight weep coming from somewhere but when you look there are no signs of leakage. The system has been bled on 2 bleed points for the cooling system is there any that I have missed?
Also when the car has been run whether you leave the engine to cool or not it shows ther is no water in the expansion bottle but when you undo the cap the pressure is realeased and the water levels rise in the bottle again, HELP I am confused as to the problem.

    My partner was a motor mechanic so the labour costs is not an issue, he has checked that the oil has no water in it and the water has no oil in it just incase is was the head gasket. He seems to have ruled it out, there is no white smoke being ommitted either.

once released the cap on the bottle the thermostat reset its self and pushed back water into container

Seems you are in troubles.
The water level rise up when you open the cap because of the pressure and temperature, even if water is far below level this is normal.
If your water is going, and there is no leakage, most common cause is head gasket starting to go.
When head gasket lose her grip and insulation, water circulating in cylinders is vaporized, and water level goes down.
If this is the case ( and probably it is) yopur car will stop for good one of this days.
Another symptom head gasket is going is white smoke from exhaust.
There are liquid testers on the market, they are quite easy to use, you should go to your car part reseller and ask the proper one for your motor, here is an example

Check here for a simple description of the problem.

Here is how the head gasket looks like.

Here is a compression test kit

Head gasket itself it is not an expensive part, but its replacement involves a lot of labor, it is definitively not a job for novices.
Check first that you do not have any external leak, and that water pump is running ok.

Would a blown gasket on the turbo of my Volvo S40 T4 1998 be responsible for a total loss of power and white smoke? Where is the turbo located??


WHITE SMOKE SOUNDS BAD COULD POSSIBLE BE A HEAD GASKET FAILURE, GET A COMBUSTION GAS TESTER AT AUTOZONE, CHECK FOR COMBUSTION GASSES IN THE COOLING SYSTEM.

Oil leak when car is on slight slope


Im not fully conversant with Turbos , but I would hazard a guess from memory that there is an oil feed from the engine to the turbo to lubricate it. I would think that the oil sump in the turbo has a seal at one or both ends. When the car is level, the oil doesn't reach the level of the oil seal, and therefore doesn't leak. When the car is on a slope, the oil will level itself out and probably be above the oil seal and then it leaks. Check if the leak occurs only when the car is pointing uphill or downhill. It may give you an idea as to which end seal is leaking.

Sounds like the power steering pump. Usually water pump will leak from its weep hole if its going out. Look for coolant leakage around bottom of water pump.

the most obvious cause is the head gasket ,its failing and drawing in the water so no problems with overheating or pressuring the system ,never mind the weekend mechanics who know more with the amount of beer they drink ,its failing as most gaskets will around the 100,000 mile mark regardless of make or model

How far do you fill the radatior


you should always fill your coolant level while vehicle is running. when the thermostat opens level will go down. however, if it "disappears" you have a leak or a serious issue. Look at your oil, if it looks like chocolate milk, you got head gasket issues probably. Also, is there white smoke coming out of exhaust? There is also a weep hole on the water pump. when the pump is going bad, it will leak water from that weep hole.

The smell of the antifreeze is coming from the drip in the water pump hitting the hot engine block and burning off.
The water pump bearing seal is bad and will Begin to get worse.
You can get away with this problem for a little while but you will continue to have the smell until you fix the water pump,
Hope this help give feedback and good luck FixYa

2001 s40 T is leaking oil into the water bottle. The head and the oil cooler were taken to the engineers for high pressure testing, both came back fine.


The test you had was for water pressure,but a blown head gasket or warping near oil galleys will cause oil to go into the water.
You need to do a compression test to see if there is a problem with the head gaskets.
