I have just purchased a replacement radiator for my 91 w250 from Radiator World. The radiator part number is cu1198 made by Performance Radiator and is manufactured in Thailand. The over all size and location of the brackets are a good match. My concern is whether the new rad. will cool as good as the OEM radiator as the tubes in the core of the new radiator are a little smaller than in the stock one. This makes the over all thickness of the core about 1/2" thinner plus the top hose neck reduces about a 1/2" where it atatches to the tank. Does anyone have experince with this or can offer an opinon.
