1999 Volkswagen Polo oil cooler

My daughter Crystal owns a VW Polo 1999 1.4 Petrol Automatic reg T571 RPN.

She has oil sludge in her coolant expansion bottle, especially arounf the cap and presumably in the rest of her cooling system. The engine oil and filler cap is clean and free from gunge.

A mechanic looked at the car and advised her that the oil cooler on the Auto Gearbox has a split in it causing the oil to leak into the coolant bottle.

Do you have a replacement oil cooler for sale that would fit her car. Any advise or help would be gratefully appreciated.

Regards

Tom

What color is the oil? Does her engine have an Engine OIl Cooler (could be a fault with the engine oil cooler)?

This site does not sell parts. It provides "Guessed Answers" to questions asked.

Thank for the quick reply. The engine oil is clear and the engine oil cooler is okay too according to the mechanic. He said there is a crack/split in the transmission oil cooler. And yes I realize that the site doesn't sell parts, I copied and pasted this without removing the last part. Any further ideas anyone?

If you provide the Transmission code, I might be able to provide a part number. See attached sample image.

Thank you Thomas for the information and suggestions. The mechanic advised that the part would be very expensive and may cost more that the car is worth.
I was hoping to try and find it cheaper on the internet if I knew what I was looking for and maybe try and fit it myself as my daughter cannot afford the expense as she is moving house at the end of the month. Kind regards Tom

You can use the search engine on this site to find reputable car parts retailers. Often the transmission cooler is integral to the radiator and the entire radiator must be replaced. If not you may be able to get an aftermarket cooler that you can retrofit instead of a stock replacement. You just need to make sure you can hook the oil passages up and mount it. Even if the cooler is in the radiator if it is the only leak you could still use this fix. If the tranny cooler is bad the radiator cannot be far behind. I am wondering if the head gasket is not bad. I know that is bad news but a coolant system pressure test or a compression test would be prudent. I think a coolant pressure test should be done first.
The link below pertains to a certain model car but explains the issue of oil in the coolant. Just use the link below;

Where in Europe are you?

Note recommended, but you could:

Remove the two coolant hoses from the cooler and join them with a piece of pipe. Take a piece of coolant hose and join the ends of the cooler.

Flush the cooling system several times using liquid dish soap or radiator flush from a parts store. Refill with the correct mix of coolant / water.

You can now drive the car, but I would stick to short trips until the cooler is replaced. Again, once I know your transmission code, I can provide a part number.

Not gonna be a head gasket issue.

North American vendors will not have your cooler in stock.

Thank you both so much for the quick replies and for the superb advise. I spoke to my daughter last night on the 'phone (She lives in London and we live in Littlestone on sea in Kent). She is so fed up with the car that she has decided to call in the scrap man to take it away and use the small amount she gets for it to save up for another car. Kind regards Tom

It's a shame if the car is in decent shape. Should be a simple repair. Scrap man probably has what she needs.

I agree. If you have not already taken it in, reconsider and see if you can get the cooler from the scrap yard.
