cooling fan going nuts.

Why is my cooling fan turning on only on cold mornings and not on hot day?
Can this be water pump issue?

Usually this is indeed a sign of pump failure. Scan for codes and if necessary start ordering parts.

If it's on all the time it could be a water pump issue.

You're on borrowed time, do it now, or you'll be left stranded at the worst possible time, have to pay more for parts for being unprepared, mechanic will have the upper hand as you now have a useless broken car and you'll have to fork for a tow. You know your water pump could be breaking/failing so fix it under your terms not it's own.

car finally gave a check engine light and a code.
po128=coolant temp lower than thermostat rating.

im suspecting coolant temp sensor or thermostat.
