Yes it is going to overheat. If It didnt need fans they wouldn't be there. You need to get those gauges working, again if they wern't needed they wouldn't be there. You just put in a new motor and now you have no idea what is going on with it or if it has any problems. It would be a shame for it to go to the shitter just becasue of some gauges. Dont get in a hurry and do it right and you will have a good running car that last for along time.
