1990 Jeep Cherokee overheating
Hi all I have a 1990 Jeep Cherokee. Motor runs great. But after driving 10 miles or so it begins to over heat. I put a new water pump in it. Now I am wondering if it is the radiator? Any help? thx

Welcome to the forum.
In all honesty, overheating is one of the most common threads on this forum and I would suggest to do a few searches. Overheating can have a lot of causes, but diagnostics will lead you the way. Really, every 15th thread or so is about this, so spend a little time diving into this and don't start throwing parts around.
To help you on the way, tell us if it's overheating at idle and low speeds (fan clutch bad for example) or driving at highway speeds (blocked radiator, thermostat not opening faulty waterpump, etc). Does your upper radiator hose gets hot? Do you see any leaks? Are you loosing coolant?
And besides your waterpump, what has been changed/flushes/modified lately?
If the vehicle has unknown maintenance history, there could be several issues going on and a thorough revision and cleaning might be in the air.
But search a bit first, I'm sure it will give you a LOT of ideas
Investing in cooling system maintenance is a very good thing to prevent more serious issues down the road...
