So I've been battling a temp issue on my 88 mustang 5.0.So some back story I bought the car it had blown head gaskets I got it replaced installed a 180 tstat new radiator. I have a electrical gauge installed into the stock port and I've also used a laser temp reader. It runs at 220 constantly. I've read and read and just find fluff information. If someone could provide some input on what to check first and most common problems. Could cheap coolant cause it to run hot? The top hose gets hot and the tstat opens and I installed it correctly. Bottom hose has a small slit in the bottom I'm going to get all new hoses but I wouldn't think it would cause it to warm that much? What do you guys think about the coolant attitives?
