I bought some radiator flush and I have my thermostat out. Would it be okay to put the flush in my radiator and perform the whole directions of the flush with no thermostat?

Hi,

Absolutely, that is fine. Actually, I would recommend it simply because there is no restriction caused by the thermostat.

Here is a link you may find helpful:

Also, if you follow the directions from the flush product manufacturer, you should be fine.

If you have a chance, let me know how things turn out for you.

Take care,

Joe
