Doubt the pulley bearing had been seized for 8 months. Pretty sure the belt would not survive that.
'Water Pump' was never an issue because it runs off of the Timing Belt....not the serpentine belt.
Glad you got everything fixed though.
I would definitely advance the timing again but I wouldn't take it to 15°.
I've run mine at 7° btc for the last 20 years with no ill effects and feel that it is ideal for MY set up (33" tires, stock gearing).
There is only so much you can/should do with ignition timing. For improved...
I'd look at the connections/wires where they enter the top of the tank first for corrosion.
But since the issue is intermittent....my first guess would be the 'sending unit' which is part of the fuel pump assembly in the tank (but a separate replaceable part) as being the likely culprit.
I use a Copper scrub pad in mine. It is 'Coarse', allows good flow and has plenty of surface area to capture the oil 'mist'. Copper will not react with anything the engine oil or emissions can throw at it.
IF the oil 'catch can' you select comes with a 'particulate type filter' pull that out and put some type of Brillo/Scrub pad in there. It will do a better job of quickly capturing the oil 'mist', having it condense and drop to the bottom.
Sounds like you have a belt (A/C belt slipping). Even if seemingly 'tight' enough....it might be 'glazed'.
IF your belt is very old or has been slipping, I'd put a new "Bando" belt on it (raw edge, cogged), tighten it and see if that solves your problem...
Grew up in Austin and went to school there. We always had a Lake House in Lago Vista, so spent a lot of my youth on Lake Travis and exploring all of Central Texas/Hill Country.
Moved away in the mid 80's after marrying...but all my family still live in Austin (out at the lake).
Don't care for...
Give it another test drive. Sounds like a definite improvement. If you went out 1431 then that was a pretty good test, pretty good hills (out to Jonestown anyway). I wouldn't be alarmed to see 190-195° F on that jaunt.
My 'modded' fan clutch (now several years old) doesn't really 'roar' upon...
Fan clutch issue then (at least). Pretty confident a 'modded' fan clutch will help (if not solve) your overheating problem.
Just fill the clutch until the fluid comes up flush with the openings (slots/holes). It probably won't take the entire 52ml and the stuff is thick...so give it time to...
No....not related to the coolant mix (water only in this case). Pure water offers the best heat transfer to be had actually.
You can test the T-stat outside the vehicle by applying heat to it either in a pan of heated water or even using a hair dyer. Watch to see that it fully opens. IF it...
I ask about the radiator.....wondering if you put in the all metal (CSF) Brass/Copper unit?
I have one in my '97 and it runs fine....but others (in recent years) have had cooling issues with that radiator. Most were resolved by going to a good quality Aluminum radiator. OEM cap is the 'best'...
Yes, 220°f in your driveway is too hot for the ambient temps this time of year. It probably hasn't gotten over 80° in Cedar Park yet, but warmer weather is just around the corner.
What radiator do you have?
Does your fan clutch move air from the moment the engine starts?
OEM radiator cap?
