This all started out with a tiny hole in my lower radiator hose. I have three questions at the end of my message. But now for some background.
I have a 93 9000 cse turbo automatic. I didn't drive much the past 3-4 days while I was waiting for the hose to arrive.
Of course today -- the day that I went to the auto store to get a few things I would need -- it decided to get worse.
The hole got bigger on my way home and the car went into the red for the last 2-3 minutes before I got home. While the car was cooling down, I did a little checking and it seems like there might have been some fresh oil near the lower right corner of the engine (closest corner to the transmission dipstick.)
Once it cooled I:
- replaced the lower hose
- replaced the upper hose (complete with new thermoswitch)
- replaced the thermostat (old one had actually started to break apart!)
- put in about 25% phosphate free radiator fluid
- a bottle of Water Wetter (or Wetter Water, I can't remember ;)
- I also changed the oil and filter (synthetic Mobil 1, 15W50)
Then I took it out for a spin. The temperature initially went up to the red, then cooled down to midway. It fluctuated between 1/3 and 2/3's for the rest of my test drive. Normally, it has stayed pretty steady just under 1/2 way up the gauge. It seemed to run a little rough, then smooth out, then a little 'off' again. Occasionally I would also smell a little radiator odor as well.
I stopped a couple of times and checked, but didn't see anything leaking until I got home. There was fluid seeping out where the upper hose joins the thermostat housing. I know it seems obvious, but does this mean the (brand new 82 deg. eEuroparts)thermostat isn't opening correctly or might it be something else ?
What else can I expect and what should I watch out for when it overheats like this?
(As it sounded like the engine was running a bit rougher and there was a bit more 'clapping'...) What can I do to minimize or correct any damage to the heads/gaskets/pistons/rings etc. short of tearing the engine apart?
TIA
