Hey Guys, I have been reading here and I think I know what's going on now but looking for some clarification. So I got this thing from a guy who told me he had just put in a new radiator. The operating temperature is as shown in attached photo once warm. When I start it the temp creeps up to 210 mark and then drops to here and stays.
At first I thought, oh good, cooler is better. It occurred to be the other day (after seeing a post on another forum) that my intermittent catalyst codes may not be a bad cat but low operating temp?
Then in reading more here it looks like it could be a missing restrictor in the new radiator. When I had a 1997 Tahoe back in the day (2001, young, dumb and all that jazz) I had the radiator replaced and same low temp. And same intermittent cat codes.
Why TF don't after market radiators have the restrictor?!? I will try the hose clamp to test. Im understanding I want to partially clamp the small hose that goes to the semi-clear plastic tank on the passenger side? Is that correct? Does anyone have a photo of how that should look like? And what type of clamp, a round screw adjusted type or a plastic scissors type?
