| Day after mishap it was time to take the wrench and put the engine back together. I managed to get new water plugs on Saturday morning even though i should have had several of then somewhere after last autumn freeze down incident. | |||
| Since i suspected one of the reasons for high running temperature being the routing of radiator hoses between the engine and radiator i already earlier decided to change the routing of the top hose and thsi was a good chance to do it. I removed one of the Multi-Wing fans for relocation of radiator hoses. And as soon as i lifted the fan off of its place i saw a loose top radiator hose. Well that surely explains why we lost all the coolant from the system. | |||
| So hose was loose all the coolant (at least most of it) was lost because of that. Engine overheated causing aluminium block and cylinder heads to expand and one of the water plugs to pop off. Partial success in otherwise quite miserable event. And there is more to come. | |||
| I also lowered the radiator some so that it's placed more like it would be placed in relation to engine while installed in car. We didn't change the lower hose just the top hose at this point. | |||
| We put in all the parts back. Valve lifting system had to be removed in order to be able to put in the new water plug since it's located right under it. There are two long bolts holding these in both sides and they were really tight. | |||
| We had forgot to take torque wrench with us so it had to be fetched from carage some 4km away. I had a bad feeling about one of the bolts when i had to use wrench to screw it in place from the beginning. It was following the thread i checked that several times, but it was just abnormally tight. I set the wrench to 45Nm as indicated in repair manual (3 steps 45Nm, 59Nm and finally 64Nm) and didn't hear the click i was supposed to. Instead bolt turned on and on and i realized what had happened. Well, change to use the repair coil set i bought earlier. | |||
| But for fixing the threads in aluminium block, engine needs to be taken apart and preferrably in workshop conditions. All of us feeling disappointed we silently removed it from the craft and it was taken to the other side of the river and to our carage for complete check. | |||
| I decided that quicker way is to buy another engine and go for 1,8l this time. Couple weeks later i got a complete Subaru Leone 4WD STW and another 1,6l engine. This small engine was so cheap and easily adaptable for my thrust stand that i bought it too since i had to pick up this complete Soob quite close where this 1,6 was for sale too. | |||
| 1,8l is still in the car and will be removed soon and changes
for the thrust stand and also new starter adapter plate will be manufactured
and maybe it'll be installed during winter time or so. I picked the car
and the engine on Thursday and Sunday the new 1,6l was installed and running
in Explorer. Test drive wasn't too promising, but new distributor cap and
that little thing rotating inside fixed that.
Also old 1,6l is almost complete. So now i have spare engine to be installed at quite a short notice. |
