·Hi Ken,
Honestly your type
Hi Ken,
Honestly your type problem is VERY difficult to solve in this environment. There are just too many variables.
Even the best techs in the world are forced to service parts that may or may not help, such as the flushing of a radiator. Because we can't see inside the radiator or even see the fins, there is really no way of ascertaining condition without pulling it out and looking at it, at which point one might as well send it off to be fully cleaned and resoldered. I do run very careful Temp Drop tests on radiators I suspect of being an issue. A good radiator should shed about 25-35 degrees across the core from inlet to outlet, w/fans running, AC off. Occasionally I have seen a little less drop that caused no apparent issues, but my best guess is about 20 degrees is probaly the minimum acceptable.
I would say definately install a new radiator cap. Cheap insurance. And of course as long lasting and durable as the thermostats are they do eventually give out. Again with the t-stats there is no way to guess condition and no way to know why one may last 20 yrs and another only 10 yrs.
You say you bleed the radiator before every drive, do you find air every time and if so how much?
