I am new here, so I apologize if I am posting this in the wrong place...
I just bought a '91 S10 Blazer last night and was told that there were no major mechanical issues. The guy I bought it from used to be a mechanic, and, what he told me was that he had taken really good care of it in the year that he had it. I had no reason to think that he was playing me because he was up front about several items; he told me that the fuel filter was ready to be replaced soon, and included a new one, for starters.
We looked under the hood and I was surprised at how clean the engine was; I didn't notice anything out of place at the time.
After exchanging the cash for title/keys, I drove the Blazer to show it off to my brother. When I got there, he looked under the hood and pointed out what appeared to be coolant standing on the top of the engine block just under the air filter, on the passenger side; it wasn't a whole lot.
This morning on my way to work, I noticed that the passenger carpet was saturated, the windows fogged up with the defroster on, and I could smell coolant. I did a search and found that the problem is most likely the heater core; no big deal as I can fix that without too much hassle.
What I'm wanting to know is if the coolant on top of the engine could possibly have anything to do with the heater core issued. I've looked under the hood and have been unsuccessful in finding the source of the excess coolant in that spot - hoses are dry, not brittle, not cracked; they look fairly healthy. The coolant reservoir was empty at this time.
He told me that he had replaced the water pump approximately 6-months ago. Although it appeared wet, it was dry to the touch.
Obviously, I'm not a mechanic. I really know very little about vehicle (self) maintenance, but pride myself in being able to handle any maintenance task that is accessible without pulling the engine out and apart.
I found this forum, and am hoping that the bright minds here could help me to troubleshoot this issue.
Any help that can be offered would be greatly appreciated.
