So, for this job my mechanic got a set of the aluminium pipes that the BA Falcon uses. Similar to the heat exchanger, when the radiator ultimately failed, coolant and transmission oil got mixed together, resulting in possible engine and transmission failure. The BA had a radiator with a transmission oil cooler inside it. The BA Falcon didn’t use a heat exchanger, like the BF and FG both do. Most people use the hoses that are supplied with the cooler kit, but this is where taxi mechanics will do things differently. There is the issue of getting the transmission oil to the front of the car, where the cooler is. Coolant hoses have been removed, and the transmission oil hoses are about to come off. The brownish black hoses on the left are the engine coolant hoses. The lighter black hoses on the right are the transmission oil hoses going in and out of the heat exchanger. If things go really bad then this could result in a damage motor (eg blown head gasket or wrecked motor) and wrecked gearbox. The risk is that the heat exchanger fails inside, resulting in coolant and transmission oil being mixed together. It does the job, but not as well as having a separate cooler at the front of the engine bay. The intention is to use the engine coolant to cool the transmission oil. Gearbox oil goes in one side and engine coolant goes in the other side. What does a heat exchanger do? It’s an aluminium box. Fitting in the car, in front of the radiator.Ĭrimping the hoses, before removing the heat exchanger.
