    Hi everyone
    I have a 97 3.4L manual Tacoma with high milage 200k+. I was driving for about an hour at freeway speeds 65-70 mph.I noticed my temp gauge was high. Not in the red, but high I pull off at a rest stop, wait for 15min. Starts up fine continue on. Drive for a few more hours and this happens again. Wait for a longer period of time and it wants to stall when I start it. This was during a heat wave 90+ degree. Now it starts fine and like nothing happened. CEL did come on.
    Does anyone with similar truck experience this? What could be the primary cause?

    It might be the fan clutch. Would explain another issue.
    Thanks.
