I have recently purchased a 86 GT-S Corolla and the oil cooler hose is leaking oil. I went to the dealer and they wanted to charge me $120 for the replacement part...

The hose is about 20 in. long and has an inside diameter of 10mm. Every site I go to online seems to have measurements only in inches.

I'd be very happy is someone could point me to someone that carries aftermarket oil cooler hoses for a better price than the dealer...

any places that repairs hydrolic stuff will have some high pressure hoses...check the specs how much psi you need and the diameter of the hose they should sell you some for much less than the dealer...

First of all, the dealer will tell you that these are lines made of Kryptonite or some such thing....Hence, the outrageous cost. Hydraulic line is made for pressures in the hundreds to thousands of pounds per square inch. the average engine driven on the street won't go over 100 PSI. You can't run hydraulic line because it has a steel inner core for the higher pressures, you can't clamp it because it won't compress and seal around the tubes. Go to a good parts store and ask them for a pressure hose rated for about 300 PSI and oil. The temperatures going to your cooler won't exceed 300F. Gates and several other manufacturers make this type of hose and it is covered in the same type of black woven cotton as the factory lines. The 10mm dimension should cross over to 3/8" ID on the hose. Buy GOOD hose clamps by a company such as Ideal and spend the money to put double clamps on all of the connections. Be sure not to overtighten the clamps. The pressure side runs from just below the oil filter typically and the return will dump back into the pan. Take your time and make sure the cooler fins are clean. Watch for leaks for a bit after you do it and you should do fine. Cost on the hose may run high but it is still cheaper than the dealer. Good Luck!
