pagurus 0 Posted May 23, 2010 Refurbishing my Aug 92 TornadoRed G60 Rado (Car1) http://the-corrado.net/.archive/forum/viewtopic.php?f=1&t=89928 Using a second car 91 Blue G60 for spares, (Car2) Sub Thread - Refurbishing the Oil Cooler This is one of the many jobs discovered along the way ... How it was done. Bits bought to do it. Things learnt along the way. Car1's (top right) had a slight leak with oil all over it. Car2's (top left) was bone dry, and turned out to be the better of the two. Car2 is definately coming in handy as more than just a supercharger donor.

There's probably a better way. Aluminium cleaner is probably a bit harsh. Can't believe how the oil cooler's water pipes coroded through on Car1. The new oil seal is visibly fatter and has a mod to help it fit better. The large central oil feed rod, fouls one of the fixing allen bolts. Happily this unscrews. The sensors have the same fitting thread and bore, so best to note how they are arranged. On Mine they are : Large one ( yellow wire ),at the back, and small one ( green wire ), to the front. Sure I was careful but one of the water pipes got damaged dismantlin Car1's oil cooler. Luckily Car2 came to the rescue with a good stand in part - phew :grin: No idea what the orange stuff was in the replacement water pipe from Car2. Quick flush with a hosepipe sorted it! The oil cooler aluminium body is date stamped underneath. The oil cooler date stamp on my August Registered 1992 Rad, was ( 03/92 ). Car2's stamp was ( 12/91 ) ! There are two engine block gaskets listed for this part. Go for the cheaper one which is listed below. Savin a bit of bread for once :eek: Used brand new engine oil to soak the new bolts in just before fitting. Also wet the gasket and block mating surface with this before fitting. Coated the top of the bolt heads with Loctite copper grease to prevent gung filling them in. Any sage comments or tips of wisdom about this info would be much appreciated.
