97 Blazer running hot/leaking coolant
97 Chevy blazer, 4.3L vortec v-6
So it is a HOT day today and I'm driving home from work air conditioner blasting and I smell antifreeze. I notice it's running really hot, about halfways between 210 and 260 not yet in the red. Oil pressure is lower than normal (normal is about 2/3 on the guage) and when I lowered rpm's pressure dropped past the half way point on the guage. I didn't notice any power loss or change in drivability. I get home and check things out. Coolant tank is empty, but oil looks fine. Fill up coolant tank, run it for a while. Still gets hot and oil pressure is down from normal. I notice that coolant is leaking from under the engine, not anywhere near the overflow tube, radiator, or hoses. I can't really see anything under the hood, and underneath it's dripping on the middle right (passenger) side of the engine. I took it out again and when idling, temp was right at 210 (still higher than normal) and when I took it up to about 45 the temp shot right up to the point it was at before and when I stopped again it went right back down. Seemed pretty odd to me because I never see the temp guage move that fast. I had the cooling system flushed about a month ago. I'll be changing oil tomorrow so I might be able to see where the leak is coming from better, but the drop in oil pressure really concerns me. I'll probably check out the thermostat too. Any suggestions on what to look for/ ideas would be really appreciated. |

In the front of the engine is the water pump which takes a bit to get to,
and a freeze plug behind the power steering unit is another good place to check. my .02 |

Look closely at the corners of the intake manifold, common areas.
