2003 Santa Fe 3.5L V6
Replaced the Timing belt (water pump, tensioner ect.) 20k miles ago (16k highway miles from cali to texas and back)
replaced the Sparkplugs and Wires (had 120k miles on them)
Just replaced the Valve cover gaskets (front leaking) while replacing these, broke the Ignition harness for the rear (replaced with part from dealer)
After replacing the valve cover gaskets, i drove roughly 200 miles through the mountians, no problems.
Did an oil change (moved from convetional to fully syntheic 10-30 Mobile with mobile filter) I live in the desert so my dad (30 year mechanic) suggested going with slightly heavier oil. Now my oil light comes on and flickers sometimes, when i drive over road dots it flickers a lot.
I just recently drove to vegas (215 miles each direction) and as i was driving through San Burnadino mountians, it started to overheat, so i pulled over and let it cool off, continued to vegas, had no issues IN vegas, on the way back i had the same issues in the mountians, Driving at 65-70 car was overheating again.
I got home, and all the fans work, with the AC on and OFF, they go into High and low.
Today, i flushed the radiator. Pulled the bottom hose, drained the system, (rusty), Used distilled water to flush the system. hooked the hose back up, filled it back up with Distilled water, Drove it arround the block, let it cool off. Flushed with Distilled water again, and a little bit more rust came out. Filled it back up with 50/50, and it Still runs hot under load (getting on the freeway and getting upto 70-80)
What should i check next? I can replace the Thermostat, but it doesnt sound like a thermostat issue.
