I felt the radiator cap and it was cool, so I opened it. As you may have guessed, the fluid was only warm.
Does it sound like a thermostat problem? I looked at the location of it and it looks easy enough to replace. Also, since I’m going to be replacing it (assuming that it is the thermostat), should I replace the radiator hose? What about flushing the system? The van has 77,000 miles on it.
Thanks in advance for the help!

Hello Glen,
That's what it sounds like to me. Try starting it up (on a colder day) and seeing if the top hose going to the radiator has got fluid going through it. Does it take a long time to warm up??

Best Regards,
