I have an 1988 FJ62 with the original 3FE (165K mi.) that has a leak that appears to be coming from the oil cooler. From what I could see tonight, in the dark and with a flashlight, it is coming from the Bolt (not shown) that the oil cooler label in the diagram from the FSM is pointing at. I put a wrench on it to see if it just needed a tighten and it actually got worse. There is a chance that it is coming from the water hose/nipple connection to the right in this picture, I tightened that not even 1/8 of a turn, but it looked like it was the bolt.
Looking for any insights anyone can share.
PO replaced the water pump and I haven't had any cooling issues, although most of December was in the negative digits Fº and my daily drive is really short. I do wonder if the water pump went out because if it leaked here before and the pump ran dry. Until tonight, I hadn't seen any leaking, but my driveway is gravel so it might not have shown up. I did notice that the overflow bottle was also empty. Heater blows hot.
