i got a zc crx 88 , when i turn the car on the cluster reading for hot and cold, the needle goes right to the top after i turn da car on for 2min,, wat could be da problem, i've checked the engine to see if its hot, but how could it be hot when i just turned it on.. does any one know wat could be the problem.

also when i hit 110kms on free way, it starts making this beep beep beep sound,, wat could that be, is dat tellin me that i'm speeding or there is something wrong
