Oil Cooler Damage

How do you guys normally test if an oil cooler is bad?

Is there any obvious VISUAL signs that are tell-tale of it having failed?

I do not have an engine oil temp gauge, so I cannot compare the two...It is next on my gadget list....I hear there is a maximum temperature difference reading that the oil and the coolant MUST fall between...anyone know this?

I might be in left field on this one.

Thank you

its now 15* difference. Used to be 25 then Ford moved it down to 15*. you get the most diffenece in temps after pulling up a hill at 100% load then you will see the temps start changing going back down the other side, let it cost.

The sure-fire sign is when you see a tan / milk-shake looking material in your coolant degas bottle.
