Ok so today was a VERY long day! I took off my front bumper and cleaned and filled the radiator overflow/reservoir tank and replaced rad cap and BOTH coolant temp sensor and coolant temp switch and problem is STILL THERE
Only that now that i actually got a good test drive i came to the following conclusion:
`Car overheats to 3/4 of the gauge or slightly higher it won't get to H.
`Overheating happens during IDLE and temp drops slowly when i go for a drive,
but will come back up at a stop or just idle. Heater on blast makes the drop faster even
in some cases below half point just where it sits at start up.
`There is no overflow or coolant dripping.
`Oil has not change no signs of a leaking head gasket at all.
`When car cools and i open the rad cap i see no bubbles, when i top it off bubbles
appear but they go away so no non-stop bubbling.
`Fan kicks in when car starts to overheat (when its about 2 lines from center)
I always seem to hear/see it at the same speed.
Question i have:
Can a bad radiator cause this? I suspect its the original OEM rad from 1999.
Should i replace the t stat again?
Why are both of my rad hoses still equally hot?
Do our fans have a low and high? Fan kicks in when i pop the hood at idle
but is there any way to check both speeds working?
Does anyone know if my rad looks like an oem one? Saw several pics from other
with different shape radiators.
Is there any add-on i can add to the coolant to lower the temp? Something like purple ice from royal purple? any thoughts?
Thanks again for everybodys help i really need to narrow down the issue and fix it! Dont want to drop much more money on good components.
Here are some pictures of my progress.
This is how it looks like after a 2 miles run.
