I did not get any error lights. Did you open the reservoir (when cold) and put the car in the run position to make sure it is flowing now?

Pump is running when light comes on
Jb4 clears error with their “delete code “ process but never reads one.
I’ll check with my other reader

I would be shocked if this coolant pump mod resulted in a materially different IAT at WOT.

Will be interesting what your other scanner says and hopefully provides the code and the description of the problem.

I am more than willing to be proven wrong with data, but years of modifying cars tells me this mod will do very little.

A free mod is worth it imo of it makes the driving exp better in any way, but if it causes problems, throws codes then i will need to reevaluate

It will burn out the pump prematurely, and that's about it. A free "mod" that will end up costing $ in the end.

The pump is fairly inexpensive though if it does help with cooling but so far there seems to be negligible difference?
