Hello All, I am planning on removing the Oil Cooler and Radiator on my Sprint GT 1050 for a winter "Deep Clean" and would appreciate some advice. Firstly, the "Fowlers" parts Fiche shows 2 off "O" rings for the bolted flanges where the oil lines connect to the Cooler (item 5 on the sketch). Part Number T3600071. The opposite ends of the oil lines which connect to the Engine only shows 1 "O" ring (item 11 part Number T3600172). Can anyone please clarify. Also is removal of the Exhaust Headers a straight forward task or are there any "lurking" problems. Many Thanks.
