94 explorer
My 94 explorer has 118,000 miles on her and I have noticed over the past four months that the coolant level in the reserve tank has dropped enough that I have had to add coolant. I have never noticed any antifreeze contamination in the oil or any leaks. Is this something to be concerned about or is this NORMAL for this engine. Thanks allot.

Happy new year and Hello new friends!
I have a 1992 Exploder which has been a very loyal means of transportation for about 263000Kms (almost 160000 miles) and when I started losing coolant, it was due to the actual radiator design... one of very few complaints I have with this vehicle. The rad core is aluminum, and the tanks on the sides are plastic. The core is crimped onto the tanks and there is a rubber seal in between. The problem that occurred is referred to as a cold leak, meaning when the engine/rad/coolant is cold, the rad leaks at the seal until the rubber seal expands (heat) and stops the leak. So when the engine is warm, it stops leaking. I tried having the rad "repaired" at a rad shop, and it lasted 2 weeks and started leaking again, so I replaced it ($273.00CAD at Canadian Tire) and I do not lose a drop now. Been fine for the last 2 years. Check under your rad next time you start it up and it is below freezing temp. Let me know what you find.

Well I wish that was the problem but I did have the radiator replaced about a month ago due to the problem you described. I think the small loss of coolant might be due to a intake gasket but I am not for sure. I did a Blackstone Oil sample and they found no coolant contamination in the oil so the problem is not that bad. And I have to admit it does not loose a whole lot and it runs great so i would just have to say that im going to drive it. There seems to be no problems from it. What is your opinion.
