I have a 1992 4.0L Explorer - the Eddie Bauer edition. I bought it used at about 120,000 kilometers, and am currently around 140,000 kilometers (about 86,000 miles I believe). Recently I’ve been having heat issues. I’ve had a few other issues in the past, but I’m worried about where these issues may lead.
Since I’ve had the Explorer until a few months ago, I don’t think I ever saw the temperature gauge pass the “RM” in normal (except for the time the block heater blew out, but that’s a different story). In the last few months however, I’ve been driving around with windows open and the heater blowing at full to keep it from entering the red zone – it comes close, but never quite leaves the normal range. Also, I’ve needed to add additional coolant, as it seems to be losing a worrisome amount.
Today I replaced the thermostat, all the coolant, oil, etc. Today was also the first day I did any research about my vehicle online, and what I found will no doubt cause me to have a troubled sleep tonight. From what I can see on this site (Dead Link Removed), it seems as though I may have a cracked head, or possibly a leak in the lower intake manifold gasket. My question to you all: What can I do to determine exactly what the cause of my coolant leak is (provided that the thermostat replacement doesn’t make everything perfect)? Are there distinct signs of certain coolant leaks?
Thank you all for your time and knowledge.
