With the autobox not liking long, hot trips, the cooling system comes in for some fettling on Ade Brannan’s Mk2 Granada.
Recently myself, Simon and the Granada embarked on the Classic Ford Tour to Germany. The cooling system wasn’t particularly happy with the continental temperatures though, and an incontinent gearbox even had to be replaced mid-trip thanks to the awesome crew on the trip!
Back in Glasgow I got to work of diagnosing the problem. Looking at the design of the gearbox cooling showed me that the oil was being routed into a compartment in the radiator which effectively looked more like a transmission heater than a cooler! Good for winter mornings, but not something that’s needed on a car which will only be getting summer use, and especially one that is likely to be on Euro trips again, too! So on the advice of Alistair at MJ Racing, a Jaguar oil cooler was neatly installed in front of the radiator, and the hoses rerouted away from the radiator. This also will allow a nice extra amount of oil capacity which is always a plus point.
I could have stopped there, but I had my suspicions about the radiator not being up to scratch. So I headed to renowned experts, East End Radiators in Glasgow. To my amazement with a split second glance Stevie had spotted it was a Mk2 Granada radiator I was holding, and even started to notice differences due to it being an import model! He then told me stories of how when the nearby M77 motorway extension opened up, they had an influx of business from caravan-towing automatic Granadas not being able to deal with the steep hill! Yes, I was in the right place!
I was expecting a recore to be necessary on the 37-year-old part, but just to make sure the radiator was flow-tested first. Surprisingly it was actually working as well as expected! Looking for an upgrade led us on to the idea of removing the redundant autobox pipework from inside the radiator. This 10 mm thick pipe fills much of the lower tank, and massively restricts flow, so the tank was opened, the pipe removed, the outer holes welded up, and everything reassembled. With a lick of paint the radiator looks like new, plus I know for sure it will now be better than stock. A car needs to be proven though, and after a month of varied summer use there seems to be zero hint of any issues. Looks like we’ll need to get it back on the autobahns then!
