another high EOT thread. Need insight
Well first post and unfortunately not super positive. Been having high EOT on my 2008 450 when driving unloaded. I'm in phoenix so it's been hot (well over 105) lately but I don't think the heat with the tune I'm running is acceptable.
So here's the deal, have a blackmax to monitor my temps. Running the non-HD tune at any level I'm able to hit upper 220's in EOT. ECT is not far behind at around 212. Truck has only 28k on it but considering were getting to that 5 year mark, I'm wondering if my coolant which I 'm sure is stock is worn out. I'm going to start with changing the coolant but I'm wondering if I'm putting to much faith in that fixing my issue and maybe I need to look deeper to the oil cooler?
Any suggestions are greatly appreciated.
