My motor is getting ready to be put back together and I was wondering since the radiator is out,should I have it checked,cleaned, or flushed. The car runs around 195 on highway and I wish it ran a few degrees cooler. Wasnt sure if stock radiators needed any type of servicing or maintenance.Im putting a new water pump on also.Theres also a 180 thermostat in it.

If it has been sometime since you have had the radiator rotted out or cleaned I would definatly do it now. If you have the cash, you might just have it re-cored. Have the shop advise you which option to do. I would ask around your local area to find a shop that you can trust. I have a bigblock in a car that originally had a smallblock and just had my radiator done. I kept my original 3-core bowls but got what was called and MX Core. It is supposed to work better than a factory 4-core. It was cheaper than buying a whole new 4-core. goodluck.

I'd say that if you don't know the history of the radiator,have it recored or replace it.

Blaster, As minimum have it vatted and flow tested at a decent Radiator shop. A new Modine 3 row is cheaper than you think if you get through a shop rather than Advance or any other chain. Hate to use the cliche "Cheap Insurance", but thats what it is!!! We charge $15 to check one out at the shop where I work, most that are older than 5-8 years are marginal at best. If yours is flaky go with a new radiator rather than a recore. As an analogy, would you buy a new or rebuilt AC Compressor?
PS: I don't own any stock in Modine, I just know what works.
