SOURCE: oil cooler seal

There are two items that can be leaking oil there. There is a gasket between the oiler cooler flange (the item attached to the engine), and the rubber gasket/seal that goes between the cooler and the flange. (the latter is the one that leaks most often as most oil change shops over tighten the oil filter).
I just replaced the gasket between the cooler and flange recently. I chose to do it quick and dirty: 1. remove oil filter 2. remove oil filter nipple (the portion you screw the filter onto) 2a. you'll need a deep well socket to get the bolt that holds the cooler tight (I believe 27mm)
2b. pull down the cooler, Grab the nipple with a pair of pliers between the flange and cooler and loosen/remove
3. remove old gasket/seal and clean surface 4. put new seal/gasket in place 5. re-seat the nipple back in. use the pliers method, just make sure you don't scar the threads where you NEED them( you don't need all of them). 6. put some gasket sealer (oil friendly) on the gasket and make sure its in place 7. tighten oil cooler onto flange with large nut and socket 8. replace oil filter and add oil as needed.
it is a tight working area, expect some scrapped knuckles, but it isn't too difficult.
good luck

SOURCE: Can I replace the oil cooler seals on 1980 Vanagon w/ engine in?

Hi!
I hate to rub salt in your wounds but after all your effort the time spent you could have the engine back in by now.
All the tin ware needs to be lifted well clear as you know the oil cooler is upright in the path of the Rotor/fan, this also needs to be raised well clear as the cooler needs to be taken off completely, you will want to clean surfaces and internals won't you?
So all shrouds to bodywork off,(Engine bay) throttle cable disconnected, clutch cable disconnected your generator wires off and finally fuel pipe. 4 bolts on gearbox bell housing and slide engine out or down for clearance on trolley jack.
All the above relates to a TypeII Split or bay window with stock engine, Not suitcase or injection.
Good Luck!

SOURCE: I got a "Check Coolant" error message from my 2005

It could be just a worn out seal or a worn out/deformed cooler. In the end the only way to know what needs to be replaced is to dismantle it and check the status of the cooler. If the cooler is OK then just put a new gasket.

I have a 2008 Nissan Altima and I took it today to have any oil change. I was told that I have a "bad oil cooler". I am female and I have very little knowledge of a cars structure unfortunately. What...


This sounds kind of odd. Most cars don't have an oil cooler. Usually trucks (especially with towing package) have an oil cooler. If the car is an automatic then you have a cooler for the transmission "oil" but it is usually part of the radiator. I would look around on line and first see if you can find a Nissan site that mentions this vehicle having an oil cooler. Unless your car is leaking oil or oil pressure reads way off center (if you have oil gauge in dash) I would be thinking you are not getting a correct answer. If car shows no major issue with oil I wouldn't be spending money on fixing an "oil" issue. Especially if car did not come with a dedicated oil cooler.

What are some cause of oil flow restictions


Assuming the crankcase is full of oil, I doubt the cooler would cause a drop in pressure. Only a small percentage of oil flows thru the cooler.
It could be the pump or strainer, but could also be worn bearings.
The first thing you should do is have the pressure checked with a mechanical gauge to make sure your electric gauge is correct.

97 vw golf 1.8 there is a squar box where oil filter fastens to. oil is leaking from top of this box. what is this box and how i fix the leak?


The box is the oil cooler. The oil is most likely leaking from the oil cooler seal. The oil cooler is the square aluminum piece that the oil filter screws onto. To replace the seal, remove the filter, remove both coolant hoses that attach to the cooler, remove the nut that secures the cooler to the block and slide the cooler off the tube. Replace the rubber o-ring seal which is available at the VW dealer. It's inexpensive. Replace everything in reverse order. Good luck

10. Start engine and check for leaks.
