overheating :(

it is about 104 in my area right now and when I was driving my S2 back I was about a mile and a half from my house when I noticed that the temp gauge had moved up to the upper white dash and stayed there I drove it the rest of the may home (about 3-5 minutes of drive time) and shut the car off the over heating light never came on and one of the fans was on found out the other was seized.

I let it cool down in my driveway for about 10 minutes then restarted and moved it to the covered shop when I restarted the temp dropped almost all the way to the upper lower white line and it ran fine.

So did I do any damage to the motor?

It's hard to say. You'll just have to see what happens.

If you find it overheats again then that could be a sign of a blown headgasket (after fixing the seized fan - if it's 104F in your area, I wouldn't drive it again till the fan is fixed).

Also watch the oil condition - to see if there is any coolant getting in the oil - it makes it look like a chocolate milkshake kinda color. This would also be a sign of a blown headgasket. As would white smoke coming out the exhaust.

If you make it a couple weeks or so and none of these problems develop, then you're probably okay.

You're probably OK if you only drove 5 minutes that way. If you're not running synthetic oil, you may want to consider using it . It saved my engine when I was having overheating problems in my '83.

I run Mobil 1 5w30 I will check it for the milkshake tomorrow

I am calling Oklahoma foreign in the morning to see if they have a fan set and I drove it later today and it never got that hot again so might have been the slow speeds I was going in town

+1 run synthetic oil in hot conditions or extreme highway conditions. It also saved my 84!!

I use the oil that is recommended in my 924S '87 and '88 owners manual.

only to the white dash should be ok.

idling, slow speeds can get hot with only one fan.
just replace the bad fan.

i use 20w50 synthetic valvoline.

Normal operating temps run from 9 o'clock to the top white line, then float between. No need to panic here.

Fix yer fans.

FYI as John said, use recommended oil. Synthetic is a good oil, but these engines were not designed for it. You may (likely will) develop oil leaks with synthetic oil.

I run 20 W 50 Castrol and change every 5,000 kms...no issues.
