thanks guys for all your help...I didn't know that the temp gauge sender was right beside the cooling temp sensor. Im almost 99% sure that this is my problem. i unpluged it last night and took it out and i looked wore out. Im getting a new sender tomorrow from a ka. Before i found the sender i got a heat gun an check the radiator and hoses and the block etc. and everything was in normal operating temp. So once i put it back in ill let you know what happens, Ive checked all over the internet and it seems like alot of people are having the same problem...maybe this is all we need !
