any component that has coolant and engine oil close by each other...examples: if the radiator has an integrated Engine oil cooler....... a cylinder head.....

if you have a coolant leak, get a napa auto parts # 700-1006 and then remove you coolant recovery tank cap, fire up the engine, let the engine warm up, allow the "tool" to sniff the coolant for a while/follow the instructions.. if you detect hydrocarbons in the blue diagnostic fluid, turning the fluid yellow... burn the car, collect insurance money, sell, or fix the problem.. hydrocarbons means you have a head gasket or cylinder head issue... ok, so I've had some beer(s).. so, I apologize for getting on my soap box.. hey, my Aunt sold her home to Ringo Starr and his hot wife, about 25+ years ago....... here is the British version of the test kit, I wish you the best of luck
