losing coolant, no visible signs. Oil is clean.. 2001 Ford Windstar
thanks for your response

 

You might be able to get a shop do this while you wait, or you might be able to rent a cooling system pressure tester.
If you decide to attempt this yourself, connect the tester to the radiator fill opening and pump it up to NO MORE than 15 psi and watch the gauge. if it doesn't hold at the pressure and goes down fairly quickly, you might look for where coolant is leaking out. Sometimes only a loose hose clamp
If it goes down fairly fast , either the connection of the tool to the radiator is faulty or there is possibly an internal coolant leak inside the engine. or possibly heater core.
If that is the case , I would suggest have a good shop confirm why. if inside engine.

 

Thanks for your reply.
Very good advice.

When last have you checked your transaxle’s dipstick? Take a look for signs of coolant
