A coolant odor, low fluid level, engine oil residue or unusual engine temperature may result from different seals, hoses, pumps or other components depending on engine generation.
How the concern should be evaluated
Pressure-test the cooling circuit where appropriate, inspect the actual leak origin and distinguish engine oil leaks from other fluid sources before recommending repairs.
