My 2001 Ls430 squeaks and overheats. What could it possibly be?

pretty generic question squeaks need specifics,
over hearting
head gasket
thermostat
old antifreeze
be careful of over heating if you blow the motor its 5k for used 12k new

When I start the car it squeaks and clicks. I let it sit and it stops. Soon as I drive off it starts clicking every time I accelerate. Then the squealing noise come back along with the overheating.

Click and Clack wouldn't be able to answer this one. Can you take video and try your best to record the sound? Sorry to hear.

look at the drive belt also known as serpentine belt see if its cracked and old its not expensive and a fifteen minute job could be a ton of other things

If you can't pinpoint it, you should probably take it to a mechanic.

It's unlikely but not impossible that the impeller on the water pump broke.

my money is on the water pump too.

My experience says clicking is a water pump bearing failing. Interesting when you add in the squeaking. It could be a freezing bearing is causing the serpentine belt to slip until it can overcome the bearing. I would pull the belt off and see if the water pump bearing turns freely. In any event, if you're having cooling issues at the same time it absolutely points the the pump.
Of course, if you're doing the pump you should see if it's close to timing belt time since you'll be in the area.
Water pump, timing belt, new serpentine, thermostat and new coolant. Independent mechanic should be around $1000 or less and the dealer closer to $1600.
Let us know how it turns out. Good luck.

Ok I took it to the shop and they changed the thermostat. It no longer overheats but still clicks when wen I accelerate.
