Sup guys, my car has been driving fine so far, only problem is sometimes (probably twice a day) the temperature needle starts going up to about 3/4 (hasn't red-lined as of yet) while I'm at a stop light for a while. Once I accelerate and drive, it goes back to normal. My fans do turn on. I replaced my thermostat about 2 months ago. However, I do know that my water pump is leaking (leaks a little sometimes after I turn it off). The amount of coolant in the radiator and reservoir is good. Could the water pump be the source of the problem?

Maybe just replace the water pump and go from there

as stated above
the water pump is a pump . so if it has any release of pressure it will take a few min.s to rebuild pressure. this may very well be your problem , although bearing failure is the most common problem in all pumps in general.
Also do you have any leaks in the radiator ?Last edited by stretch JDM; 04-08-2011, 02:55 PM.

Some things to check for.
How are your hoses, I see you said the overflow tank and radiator hull is filled. How often do you add to it? When you're underneath the car check to make sure your IM is not leaking as well.
Head gasket. Have you had it apart yet since owning it?
Water pump, it could be bad- but check tension on the belt first.
Are there obstructions in front of your fins? Do you have an A/C condenser?
How is the thermostat?
In terms of the water pump, you want to ensure where the leak is located; albeit bad seal, check the weep hole etc.
If you do happen to remove the head, one thing I should mention is to check the condition of the water jacket. Double check to make sure there is no calcium-like buildup inhibiting smooth coolant flow.
If you have any issues driving the car reliably daily after the initial onceover procedure feel free to PM me or other knowledgeable members here.
