Engine Oil Cooler Replacement
Post 3. Post 4. Post 5. Mar 21AM. Post 6. My 99 T6 also leaked from the PCV seal, it sprayed through the dipstick all over the inside of the hood, it was a nasty scence. Post 7. The turbo return lines can be seen from under the car. Remove the sump cover and shine a light up the back of the engine block. You will see two lines wind there way down to the block. There are two flange gaskets by the turbo and two o ings where it comes into the block.
There is only two bolys to undo on each flange and then you pull the line out of the block. I was talking to the volvo mechanic and they said they remove the right axle on a right hand drive car and this gives access to the right hand side at least. You could try accessing from the top I suppose but would be tricky. I did the oil pan o rings recently and it was such a major job I couldnt face the turbo return lines job even though with the sump off it would have been easier.
The power steering lines are also visible from below and much easier to access. Check the colour of the oil on the ground. Mar 21PM. Post 8.Discussion in ' Trucks [ Eighteen Wheelers ] ' started by paulib70Jan 5, Log in or Sign up.
Find Trucking Jobs. Jan 5, 1. Can anyone tell me what happens when an Oil Cooler goes out in your truck. I have a freightliner and oil is all over the ground. One shop told me that it was my Oil Cooler and another shop said it would be antifreeze all over the ground. Please help so I dont run into a ton of money for fixing something that is not broke.

Like one post asked, what engine? JoewJan 5, Jan 6, 4. The engine is a detroit 60 series. Thanks for the reply. Jan 6, 5. The engine is a Detroit 60 series. Jan 6, 6. Jan 9, 7. FreightillacJan 9, Jan 10, 8. Most times you will have oil in the radiator. Oil pressure lbs0 is more than water pressure lbs so oil goes in water. But anything can happen in trucking! Jul 15, 9. Jan 6, I had that happen to mine, Detroit sits in a fld, oil in water, but I had no water in my oil, when your oil cooler is weak, at idle, you should smell a hint of antifreeze, coming from your blowby tube, stick your finger up in bottom of your blowby tube to see if you have grey matter, or GUNKin it, if you do, that's where its coming from.
I replaced my oil cooler, oil filters, and cleaned out my valve cover and blowby tube. It works Show Ignored Content. Draft saved Draft deleted.

It uses engine coolant and to a lesser extent, airflow to cool the engine oil. Cooling the engine oil is vital on turbocharged engines. Over time, oil coolers can corrode internally.Volvo major oil leak
This eventually leads to both oil and coolant leaks. Having the coolant mix with the engine oil can damage the engine.
In this article, I'll go over the steps involved with changing the oil cooler. Replacing the oil cooler is pretty easy although it does require you to jack up the front end of the car as well as draining both the engine oil and the coolant.
The oil cooler is located at the rear of the oil pan as shown here. Loosen and remove the four T30 Torx screws holding the oil cooler to the oil pan. Large Image Extra-Large Image. Now loosen the hose clamps holding the coolant lines to the cooler green arrows and pull the coolant lines off.
Have a drain pan nearby to catch the oil and coolant that leaks out. Turn the oil cooler to one side to let all the oil drain out. When installing the new oil cooler, replace the two sealing rings green arrows shown here. All that's left to do is clean the mating surface on the oil pan, attach the new cooler and hook the coolant lines back up.
Of course, make sure you have fresh engine oil in your C30's engine. Got more questions? Join us in our Technical Forum Message Board and ask a question to one of our many automotive experts.

Can I start and drive the car to have the timing adjusted without any damage? Do you. This repair is very complicated and failure to time the vehicle right will result in severe engine damage or at the very least damage to the valves.
You need special tools to lock the cams in place since the cvvt hub does not have a guide to install it back. There is a procedure that needs to be done to set up the cvvt hub timing as well or you will get a check engine light on. If you want to reseal the cam cover you need special tools as well to remove the cover and install it. If you are serious about doing this repair yourself let me know and I will get you the information you need to do the repair.

Ask a Car Question. It's Free!I suppose that any place oil escapes from the oil circulation system, only to find itself in a place where it should not be ie your driveway or all over your valve cover could be considered a leak. But keep in mind there are a few other ways you could be losing oil in a Volvo XC90 that may not fall under the category of a true leak. That sounded confusing, so let me explain:.
When cam seals wear out, oil can seep past them and leak down the front of the engine. What makes this leak hard to diagnose is that you have to take the timing belt cover off and really look hard to find the source. Now, it could also be that the seals were fine and that excess crankcase pressure is the culprit. If this is the case, you may be looking at some repairs in your future. A leak from your oil fill cap could mean that you have excess crankcase pressure and the pressure is finding its way past your old, tired oil filler cap gasket.
Contained in that crankcase pressure are blowby gases from combustion along with hot oily vapor which is essentially the gaseous form of oil. When you have excess pressure in your XC90 crankcase, that pressure wants to escape, and will do so starting with the weakest spots — usually a seal or gasket of some sort. This could be a cam seal as noted above or it could be your valve covergasket and it could also be your filler cap gasket. If you have a leak here, get a new gasket.
Speaking of which…. This hose was a weak point on earlier models and has since been modified, bu there are still a lot of XC90s out there with the old hose. The hose gets brittle and cracks. Hot, oily vapor escapes into the relatively cooler atmosphere, condenses and pools. This is a vital system on your XC90 and when it gets backed up it causes oil leaks.
Essentially the system relieves the crankcase of pressure, which avoids many of the leaks noted in this post. Crankcase gases from the XC90 are removed from the crankcase by vacuum or by pressure when under boost and sent into the intake airstream prior to where the intake air passes through the charge air cooler.
Still with me?
As the filtered air and the blowby gasses pass through the cooler, the hot air that contains oily vapors cools, condenses the vapor into oil, making it heavy. The force of the intake carries some up and through the throttle where it dirties the throttle plate and then gets burned in the cylinders. However, some of the condensed oily vapor settles in the throttle pipe and rolls down to the lowest point — the junction between the charge air cooler and the ETM pipe.
This joint has no rubber to help with the seal — just two plastic pipes held together with a hose clamp. This is where the oil seeps out. If the area is shiny and coated with oil. Your best bet is to Take off the intake pipe, clean the pipe and the connection on the air cooler, and re-install the pipe making sure the hose clamp is tight. Slide under the car and look up using a flashlight.The oil cooler on any production vehicle is an essential engine component designed to keep modern cars, trucks, and SUVs running smoothly on the roads they travel daily.
Whether you have a BMW or an older, yet reliable Nissan Sentra, the fact remains that the cooling system on any vehicle must be in working order during all types of weather and driving conditions. Although most drivers never have interaction with their oil coolers, keeping them in working order will extend their lifespan. However, like any other mechanical component, they can and often will wear out.
These types of coolers are usually of the water-to-oil type of heat exchanger. In most vehicles on the road, engine oil is fed to the oil coolers from an adapter that is located between the engine block and the engine oil filter. The oil then flows through the tubes of the cooler while the engine coolant flows around the tubes.
The heat from the oil is transferred through the walls of the tubes to the surrounding coolant similar in many ways to the operation of an indoor air conditioning for residential homes.
If the vehicle is serviced as required, including routine oil and filter changes, the oil cooler should last as long as the vehicle's engine or other major mechanical components. However, there are some occasions where staying on top of maintenance will not prevent all damage potential for an oil cooler. When this component begins to wear out or has broken, it will display a few warning signs.
Noted below are a few of these symptoms that can alert a driver that their oil cooler may need to be replaced. One of the components that are part of the oil cooling system is the oil cooler adapter.
The adapter connects oil lines to the cooler itself and another adapter sends "cooled" oil back into the oil pan. Within the adapter is a gasket or rubber o-ring. If the oil cooler adapter fails externally, engine oil may be forced out of the engine. If the leak is small, you may notice a puddle of engine oil on the ground underneath your vehicle or quite possibly a stream of oil on the ground behind your vehicle.
If you notice any oil leaking under your engineit's always recommended to contact a professional mechanic so they can determine where the leak is coming from and repair it quickly.
As oil leaks, the engine loses ability to lubricate itself. This could result in increased engine temperature and premature parts wear due to increased friction from the lack of proper lubrication. Similar to a loss of oil, an external oil cooler failure may force all of the engine coolant out of the engine. If the leak is small, you may notice coolant puddling on the ground underneath your vehicle.
If the leak is a large one, you will probably notice steam pouring out from under the hood of your vehicle. As with the above symptom, it's important to contact a professional mechanic as soon as you notice a coolant leak. If enough coolant leaks from the radiator or oil cooler, it can result in engine overheating problems and mechanical component failure.
If the oil cooler adapter fails internally, you may notice engine oil in your cooling system. This happens because when the engine is running, oil pressure is greater than cooling system pressure. Oil is forced into the cooling system. This will eventually cause a lack of lubrication and can severely damage your engine.
When the engine is not running and the cooling system is pressurized, coolant can be forced from the cooling system into the oil pan.
High oil pan levels can damage the engine by the crankshaft slapping the oil as it rotates. Any of these symptoms will require flushes of both the cooling system and the engine to remove all of the contaminated liquids. The oil cooler adapter, if it is the failed component, will require replacement.Welcome Guest Log In Register.

View Member Profile. Jan 7AM. Post 1. I just bought a V70 loved my but I am pretty sure I got taken The dude cleaned the car real good I know about the oil leaks with Volvos so I payed particular attention when buying this - no obvious leak Anyway, now after miles or so I have a massive leak I have researched this site and found great info I took the car to a "stealer" to get their opinion So here are my questions I was thinking about cleaning up the oil and putting some die in and looking for the leak that way When I look down behind the engine on the drivers side I was going to remove the clutter and check this more closely How should I proceed?
