Hello there!
It sounds like you’ve got oil mixing into your coolant, which isn’t good but can be diagnosed. Since there’s no coolant on your dipstick and your transmission fluid checks out fine, the oil is most likely coming from either a failed head gasket, a cracked cylinder head, or possibly a compromised oil cooler if your truck has one.
Here’s the rundown:
1) Head gasket issue: This is a common cause. Oil and coolant passages run close together, and a blown gasket can let oil seep into the coolant system. You’d also want to watch for overheating, white exhaust smoke, or rough running.
2) Cracked cylinder head or block: Less common but possible if the engine has overheated or been stressed. A crack could create a path for oil to enter the coolant.
3) Oil cooler failure: If your truck has an oil cooler (often integrated into the radiator), an internal leak can cause oil and coolant to mix. It’s worth checking.
What to Do:
1) Test the System: Start with a compression or leak-down test to rule out a head gasket or cylinder issue. A combustion gas test on the coolant can also help confirm if there’s a gasket leak.
2) Inspect the Oil Cooler: If equipped, check for leaks or signs of failure.
3) Flush the Cooling System: Once the problem is fixed, you’ll need to clean out the contaminated coolant thoroughly to avoid further issues.
4) Seek professional help: A mechanic can accurately diagnose the issue and provide the best course of action.
Prevent Further Damage:
Avoid driving the truck extensively until the issue is diagnosed and repaired, as oil in the coolant can impair the cooling system’s function and lead to overheating or further damage.
