High lead in coolant sample????

[funjnt]

Morning all. I just received my test results from a coolant sample. I have used test strips previous three years and wanted to back them up and get a detailed check. Everything looks fine in coolant except the lead content. Here is what J&G said.

Flagged data does not indicate an immediate need for maintenance action. Continue to observe the trend and monitor

equipment and fluid conditions. Lead from solder corrosion in the radiator is at a MODERATE level; Lead corrosion (solder

bloom) may be from the radiator, heat exchanger, oil cooler, flux, and/or residual from a previous issue. Note slight FOAMING,

which can cause loss of heat transfer; The glycol level is at the maximum for freeze point and boil point protection, do not add

concentrate. Resample at normal interval;

Is this a sign of a radiator starting to fail? Oh crap if so. It doesn't recommend a flush as that wouldn't stop the solder bloom I guess. Ours had a radiator with bolt on tanks so I am assuming it is a replacement from original of course.

So if anyone is familiar with this let me know. I can also attach the report for reference.

When the sample was taken, was the engine oil hot after the engine was up to temp?

Yes. I warmed her up before pulling coolant sample. Ran her for about half an hour maybe?
