Hey newbie here I bought my first dsm last year junkyard fine bought a fuel pump through it in and it started unfortunately now it has an over heating issue! I put a brand new thermostat, gates 1k (could be wrong on the 1k but is a gates racing water pump) and then New coolant as well as relays for the fans I noticed the fans weren’t turning on so I by passed the relay to have them on when battery is connected and unfortunately with all this replaced it still over heats on idle when I go down the road about 140 it starts to cool down and goes back to normal temperature! Till idling again. The only issues I noticed is the over heating and lights flickering I did change the alternator and battery not to long ago as well. Any information/types would be amazing it’s a dream car of mine but is currently causing a lot of head ache! I typed it up but most if not all comments say replace this and replace that which I did and still no luck! Thank you I’m advance.
