Good morning guys, back working on my daughters car, wanting to change the rear end fluid any recommendations on fluid for it? It’s a 1972 dart 318 7/1/4” sure grip. Thanks guys Ps also what temp thermostat? Billings Montana area.
Perfect I’m going to pull the old one out when we switch the radiator this weekend how much of that sg fluid goes in there?I run 75/90 with the stand-alone GM SG fluid, added.
I run my engine at a minimum coolant temp of 205, but it was built to do that. You best run a max of 180 until you have proven the cooling system is up to handling more.
