Charles Durning's Journal --
Over the years there have been discussions about the need of the factory oil cooler. So just for grins I did a search and found lots of discussions about the factory oil cooler, both pro and con. In the last discussion Basil Adams brought out an interesting point that a heat exchanger would do a better job of stabilizing the oil temperature. He also pointed out that at one time Moroso offered a heat exchanger that he uses. I did a little looking around and only found bulky exchangers in the hot rod industry so why not take another tack. Back when I was employed in the diesel engine industry a compact Modine design exchanger was commonly used. Basically the heat exchanger installs between the oil filter and the filter head. Even my Nissan Frontier has one of those as do many other car brands. So I did a little research in my reference materials and found a Perkins applied part number 2486A218 or aftermarket P2486A218. Those are widely available from Perkins Engine Company as well as many aftermarket suppliers. Most are stainless steel. I also found that the exchanger for Hyundai/Kia cars is exactly the same as the Perkins offering at a much lower price. The same cooler is also used on the iron head SOHC 2.3, 289, 302, 351 Ford engines as part of a towing package. Though the Ford adapter bolt will fit the MGB, the Hyundai/Kia will not. In that case the Perkins adapter bolt pn 2486A225 will work with the 8 plate coolers and 2486A226 for the 10 plate coolers. To install the heat exchanger on the MGB filter head, it’s just a matter of installing a new stand pipe in the adapter bolt if you want to retain the stand pipe. Then it’s just sourcing water from a high pressure point like the heater valve port and also a low pressure port. I made a spacer between the head and the water outlet for the low pressure. The flow does not have to be great, just a pressure differential. The water hose for the Perkins, Ford, Modine, and Hyundai are 5/8” ID. The hoses are easy to route cleanly. They can be tucked in behind the alternator. I believe there are some benefits for our little engines and could clean out some of the hose clutter in the engine bay. Just throwing this out as a possible solution to the oil cooler dilemma. Hyundai/Kia heat exchanger (oil cooler) can be sourced inexpensively The Hyundai'Kia applications are; The Hyundai/Kia adapters are 20MM so they won't work for the MGB. Compatible with 2006-2015 Hyundai Sonata; Compatible with 2010-2015 Hyundai Tucson; Compatible with 2011-2016 Kia Optima; Compatible with 2011-2017 Kia Sportage Replacement OEM ( Original Equipment Part) Number: 26410-25402, 26410-2G000, 26410-2G100, 2641025402, 264102G000, 264102G100 4/27/2021 Success! No more oil cooler hoses. The heat exchanger performs as expected. Engine temps remained the same and oil pressure is up slightly at highway speeds 4/30/2021 I found that cylinders 1 & 2 were running a little hotter than cyls 3 & 4. I suspect that the exchanger plumbing permitted mor water flow for the back 2 cylinders. To address that issue I put a flow restrictor in the hose that attached to the cylinder head. That evened out the cyl temps.
