$400? That's way high. You can probably find a used one on here for sale or even a new one on eBay for way less then that. And I'm not sure on the 4g64, but on the 4g63, it's all of two bolts and a rubber o-ring. Quick and painless to change.
My lower hose was cold after a tstat replacement. Went and bought and OE Exact and the problem went away. Previous tstat was a cheap Stant. ( Junk IMO. )
Problem solved. Junk Stant thermostat was just that, junk. Went to Napa and bought and OE Exact, which I might add looked identical to the OEM unit minus one coil on the spring, and temps are a steady 195 now. Goes to show, at minimum, to buy an OE equivalent thermostat.
Hmmm I haven't been seeing status updates through my link on here. Any who, its been doing around 210 city and 220 highway. Guess I'm not super concerned about it. What's odd though that when I park it, its normally at 209, then it will creep up to 216 even with the fans on. If I give it a quick...
What rpm is your idle at? Mine was at 1100rpm after driving and it tripped the TPS code. I adjusted the BISS 1/4 turn and it put me at a perfect 800rpm all the time.
Leak-down is on my To-Do List now. I tried bleeding it today two ways, w/ the rad cap off and coolant in a funnel while squeezing the hoses, and by doing per the manual recommendations. ( Start car, warm up to tstat temp, rev to 3k 3 times, check coolant level, rinse and repeat. ) Which I will...
So she's still overheating. :/ Dunno what the deal is. Fans are working, coolant lvl is fine with a 50/50 mix, new waterpump, new t-stat. Maybe something has failed? I kept my old OEM tstat that's stuck open a little. About to throw that back in. :/
Welp today I decided to take the overflow and clean it out. Had less then an inch of coolant in it. And the Low Coolant Light would have never told me because the wires were corroded away. It appears that there was Dex-Cool in the system at once. :/ Anywho, I cleaned out the overflow and went...
OK question. Since the radiator cap was bad and holding no pressure, could that have let air into the system? Reason I ask is because the overheating has subsided for the most part and the overflow has less coolant in it. Could the system have burped itself of the air pockets and replaced it...
Ok so I replaced the radiator cap because it wasn't holding pressure at all. Start driving and it's still overheating, and now I can smell coolant slightly, but not when the heat is on? I am so confused lol. I don't think it's leaking through the head-gasket, the exhaust doesn't smell sweet...
As everyone else stated, scrap those Bosch plugs. They are terrible. I had the PO300 on my old car using those. Swapped back to NGK's and the problem went away.
So over the holiday I took my car on a longer then usual trip I was having temperatures spiking around 220 going around 50mph. As soon as I'd leave off the throttle it would drop down to 195 or so. As soon as I get back into the gas though the temperatures rise. Also, the heat is blistering hot...
