Okay, I'm so effin confused or where to step next, I'm not gonna drag this out. Had some coolant leak, flushed coolant system, more leaked, replaced thermostat, nipple on top radiator broke driving home, temp ran red. Got home, fiberglassed new nipple to radiator, flushed and filled system. Started, drove up the road to get it to operating temp, was fine for a couple min then slowly started to run hot again. Got home, shut it down, coolant spewing from overflow tube. Let cool down refilled system. With cap off bottle started car, as it passed operating temp coolant started boiling. Shut it off. Next day went to start it nothing, try pull starting it, nothing. ODB scanned, pulled code for bank one running rich. Confused pulled rear leading plug, was dark outside so what I thought was coolant on the plugs was just a lot of fuel and oil on them. Cars up, on stands and before I pull this motor out of it for no reason. Any suggestions?

I don't know how long the engine ran while it was overheated, but sadly for the RENESIS it does not take much to kill it. Once the temperature (dummy) gauge in the 8 starts to move if you don't shut id down immediately, your pretty much screwed. An aftermarket coolant temperature gauge is a must have for this car. If your sure coolant is circulating (water pump) you can try replacing the radiator cap, sometimes it's that simple. If no joy, replace the coolant bottle. If you get everything going and she run correctly, get a new radiator as well. That repair will fail, and it can cost you an engine if you have not already lost it. If you pulled the plugs and you don't see coolant, that is a good sign, but at the moment I can not come up with any logical reason why it would not start unless the engine is already done for.

That's what I figured as much! Guess I'm gonna start the pull first thing in the morning. I'll keep you posted on what I find.

Yea, keep us posted on what's going on with it, I would be interested. I would probably source parts before I pulled the engine though. If your going to open it up, you may as well rebuild it properly. Hopefully the irons and housings are still in good shape.

Well all I know is there was a bunch of **** in the coolant ports that wasn't supposed to be there. Looks like I'm gonna be looking for a new motor.

Yea man that sucks I hate to be right when it comes to that kind of stuff. Are you going to try and rebuild yourself? Depending on your financials, I would opt for a rebuild from a reputable re-builder, but I don't enjoy pulling and rebuilding engines nearly as much as I used to. I just assume pay someone else to do it.

Motors pulled, took some pics of the gunk that was in my coolant ports and my thermostat. Gonna try and break the flywheel nut and the e-shaft bolt tonight. But I think I'm gonna attempt the rebuild myself.

That's pretty nasty. That could be a result of the overheat it self, or just build up over time from not changing the coolant regularly. A maintenance item that is often overlooked on many vehicles. Well good luck on the rebuild. Make sure you don't skimp on a good set of seals and inspect your internals real good. How many miles are on the engine?

VeXeD

226,000 miles. But that's not from neglect on the coolant I can tell you that. I changed it regularly, flushed out and refilled lol.
