Okay, so, as some of you know, I've been around the 6g motors for a while now, and the Verada is pretty familiar to me. However, my stupid engine service light continues to keep coming on after I've replaced about six different parts. This time its the thermostat. However, pulling the thing out of the box and going so far as to remove the air box intake and plastic bs engine cover, I cannot for the life of me figure out where the tstat goes! I found the coolant temp sensor location (which was shot also) but every where I look on the coolant lines I can find anything remotely close that looks like it houses this gigantic thing. Can anyone help a lady out? It's frustrating me :(

I think for memory it under where your top radiator house connects to the block.

You can download something called the workshop manual, some people have links to it in there signature. Verry handy thing to download. Saves lots and lots of tine

The thing is I have no computer. Also, the upper radiator house doesn't lead to the thermostat housing, only more coolant lines.

These motors run a reverse cooling system where as the thermostat is on the inlet not the outlet hose, the thermostat is located on the lower rad hose inlet

Also, you have your check light on or the spanner, either way, neither will be activated by a thermostat.

Well, the code came up as a p0128. And its freeze framed. Which means it won't delete until its fixed. Ive replaced the temp sensor and added a ton of coolant. Any ideas?

So where did you get that code from, a Magna will give you various coded but have never seen that one

Also, you have not answered my question, is it the check engine light or the service spanner

Also remember too much coolant is more harmful than no coolant as coolant in too much concentration is very thick and will not flow

I had come across references to USDM Evo 8s having ODB2 support in addition to MUT-II, but this is the first hint I've found that some Diamantes might also have it. Very interesting!!

That's the code I got.

The service engine light is on. Yes, I know that coolant is bad. But the overflow was just a hair bit low so I added 50/50 mix.
However nothing seems to be working and its starting to agitate me.

As Madmagna said, follow the lower radiator hose to the cylinder head and the 3 bolt housing contains the thermostat. make sure you replace the o-ring as well (the new thermostat may have one on it already).
You may as well flush the old coolant while your there as you will lose a lot of it and it is easy with the thermostat out.
That code you have does not look like it is from an australian spec car as i don't believe our 3rd gens use OBDII codes.

I finally had time to change the tstat today. Car runs a lot better and WOW does he run. It's like there was a performance upgrade. The old one was the oe one and after we literally torches it it refused to move. Just kind of reminder, a healthy one is a good race car. Lol
