After some overheating and possible vapor lock issues over the past several weekends, today I was taking my 70 FJ40 over to the dealer for some more checks. I was a block from the local Toyota shop when I heard a pop and smelled and saw coolant. I took it the remaining block to the dealer and good news is I was still only about 1/2 way on the temp gauge. (Would have stopped if it started going on up.) I got the call from them saying they think it is one of the freeze / pressure plugs that blew out. They say possibly as much as $2000 to fix it, but they have not gotten into it to see yet. The motor was rebuilt by the PO and I do not have much history on it other than it has less than 5K miles on it. PO is not around anymore to get in touch with on who did the work. Anybody have experience with this...How much to realistically expect to have to pay? Any options other than the dealer? Other things to look for in addition to the heater hoses for the cab heater / rear heater? Searched and found these 2 comments: 1. I am pretty sure you gotta pull the flywheel to get to it. first check the hoses to eliminate the easy fix then if it's still leaking you goyya pull the trans/transfer, CLUTCH. / flywheel and bell housing. like I said it's a bitch. 2. You can replace that hose over the top for a quick fix, if I remember right there are some hard lines behing the block. I have drilled a hole in the firewall on a 40 series before to replace the freeze plug on the block. I appreciate anything any of you guys can add. I am learning every time I search but am also running into more work than I have the skills and definitely the funds right now to complete.
