What does your datasheet say the operating temperature is?
How does “really hot” compare to the operating temperature?
What is the current draw?
How much power does that current draw produce compared to the expected rated operational power.
What is the operating RPM?
What is the datasheet’s operational RPM range?
I don’t know the answer to your question, but these are the type of questions I’d ask when I’m trying to understand if some component’s behavior is anomalous or operational.

Actually I tried searching for it, but could not find the datasheet for it. This was given to me by a friend. I believe he bought it from AliExpress. As for current, I’ll, measure it and let you know in a few days, I’m traveling right now.

If you are in a pinch you can wing it with the datasheet of a similar component by a reputable manufacturer. Just know that you can’t quite trust the sheet but it should give you an idea of how a sane pump should operate. Like if a similar manufacturer makes a pump with an expected operating temp of 80C and yours is 150C, probably don’t need the exact data sheet to know that may be a problem.
So find all the 12Vdc water pump datasheets for pumps of similar form factor to yours and cross reference them to get an idea of common values. This will give you an idea of if your pump is behaving.
All you care about is temperature so should be easy enough to work out from 3-6+ datasheets. However many you are able to find.

I found a similar product with some number on its side. But so far nothing is coming up. I’ll keep searching.
