Question about 1997 Volvo 850

1 Answer

Hi-96 850 T5 -- loses water during 'slow speed', in slow traffic. Long trips at speed, no problem. Pressure check carried out on numerous occasions, at different garages - no sign of leak. Turbo was overalled and my thinking is it could be losing water through Turbo ? ?

Hi.

There is no way that the coolant can leak inside the turbo, as coolant does not circulate inside the Turbo.

If the water you are talking about is the coolant liquid in the refrigeration system, and there is no external leak or overheating, then it usually means that the head gasket is starting to go.

Ensure that the cooling fan is starting and working properly, or the problem may be overheating, with water evaporating from radiator or bottle cap.

Water leaks inside the engine block and gets vaporized inside the cylinders.

The problem does not happen much when you drive at speed on longtrips because in this conditions there is less heating than when you drive using lower gears and the engine stays on while you are standing in the traffic.

If the problem is the head gasket you may get some collateral symptom.
Sometimes oil or fuel may get mixed with coolant. This can be noticed inspecting coolant in the reservoir bottle. Also check if there is sign of contamination on oil.
If the leak is big you also get white smoke coming out from the exhaust pipe.
If the head gasket leak is big you will also notice reduced power, particularly up the hill, and when trying to reach top speed.

A proper diagnosis is done measuring cylinder compression. This must be done at the garage.

Regards.

    Hi T.

    Thanks for your update.

    It would be interesting to know how it goes after the long trip. I agree that a bad head gasket looks quite strange, particularly if car can drive long distance without consuming water.


    I am going offline now. Speak you later.

Position of the temperature sensor


This is a normal condition for this model and many more. There maybe an issue with your engine oil or coolant systems. If you can flush the radiator & coolant system clean on next service & replace with a fresh quality brand of new coolant then you may have solved some of the problem. The other is if your rad fans are kicking in enough or at all. So do a stationary check in your garage. let the engine warm up on idle. Then when it reaches a heat that will kick in the fans check what the Temp-gauge is reading & make a note.
You may have a weak oil pump or water pump. Check the pumps records & see if they are newish or first day. Water circulation is very important in a cars system. So in slow traffic the engine is running at low rev's & gets hot due to slow air speed through the rad. So the water pump is there to keep the pressure up at all times. It could be the No:- problem with your car.
After that get an engine oil pressure test done & compare with the results data spec-sheets from its manual.

Just bought a 96 rav4.need instructions about when and when not to engage the 4wheel button . 5 speed manual has the differental lock button on dash


Hi Ed, The 4 X 4 is selected after slowing to about 20 mph and is best deselected at standstill or very slow speeds. On occasions you may have to stop and reverse a short distance to get disengagement. The differential lock should be engaged in the same way as the 4 X 4. It should be used only if traction is lost and the vehicle loses traction with a wheel spinning free. Never use diff lock on hard top roads and always disengage as soon as possible. Regards John

Can wheels and tires affect gas mileage?


Well braking will drastically reduce your fuel economy, as of course this is taking the inertia energy of the vehicle which you built burning fuel in the engine and then reducing that and changing that inertia into heat.Your tyres do pretty much the same thing as they are a trade off between low rolling resistance and grip which helps you turn and brake. The reason trains have steel wheels is because they turn on tracks, although their braking distance is severely affected. You need to stop quickly in a car and corner safely enough to not end up in a ditch each time you take a corner, and this is why you have high grip rubber tyres on your vehicle.Typically the best way to reduce rolling resistance with your present set of tyres, is to keep them inflated up to pressure, or even slightly over pressure, which most vehicles can afford to do. (arround 5 P.S.I. will do)Other fuel saving techniques which can drastically improve performance are:
1) Remove excess weight such as the spare wheel, jack, wrench etc. Carry a can of tyre sealant instead for minor emergencies.
2) Remove any excess baggage which doesn't need to make permanent home in your car.
3) Remove any unused bike racks, roof racks and spoilers from the car.
4) When driving keep plenty of room between yourself and the car in front. This allows you to use lighter braking force when cruising at speed and also allows you to get off the gas earlier when stopping.The same goes for looking well ahead in the road for red traffic lights or stop signs. Get off the gas early if you are going to be stopping up ahead anyway!
5) Best fuel saving tip overall; plan your route ahead of time. If it's a route you are unfamiliar with then driving around in circles trying to find it is not going to save any fuel at all. Planning ahead and travelling during low traffic volume periods can save a huge quantity of fuel.

6) Share your supermarket/shopping mall trip with a neighbor or friend. You can share the cost of fuel and reduce the number of vehicles on the road at the same time.


7) Manage several errands in one long trip. Cars by far use the most fuel on cold start and during cold running, as well as suffer around 80% of engine wear during cold start only. By keeping your car up to temperature on a longer journey, you can improve your average fuel economy and reduce wear and tear to the engine internals.


8) When accelerating up to cruising speed, use around 75% of the available engine power. Only reserve this method for times when there is little traffic ahead and you can maintain safe braking distances ahead. Getting up to speed more quickly actually saves fuel in the long run. I really don't mean burn the rubber off the wheels and burn your clutch out kind of acceleration though, so take it easy!

1989 Toyota Land Cruiser overheating- REPLACED ENTIRE COOLING SYS


Do a cylinder leak down test. Hook up a airline to each spark plug hole. Bring each cyclinder to tdc and listen for air leak. Possibly in the radiator. You can also reverse the process by doing a radiator leak down test. If you hear bubbling in the radiator bad head gasket. Remove and replace head gasket.
