Soooooooooo, this update will be an interesting one.....
Since changing the loom, I've either been suffering from one of 2 issues;
1. Dodgy loom feeding the temperature gauge
2. Overheating problem caused by airlock or thermostat
The first time I ran the car up after changing the loom on Sunday night, as soon as I pulled out of my grans drive, the temp shot up to 110 degrees on the gauge.
It went back down to about 90 after a while and stayed prettymuch there for the remainder of the journey.
On Monday morning it did the same thing. When I got in to work, the temp was still high, so I got out the car. The rad was luke warm, when I unplugged the fan plug after 2mins of the fans being on it was stone cold. The Rad hose was also cold.
Monday night I went down to Eurocarparts and bought a replacement 'stat thinking it would solve the issue.
Tuesday the issue was the same on the way to and from work. I was in Haslemere after making another stop in at ECP and looked down and the gauge was up at the line bordering the red. FUCKKKKK!! So I pulled in about 30secs later and switched the car off. Turned it on 2mins afterwards (fan plug unplugged, but rad ice cold again after 2mins), and the temp stayed around 90-110.
I rang Ruan when I got onto the A3; he suggested it was likely an airlock and to pull to the side of the road and get it bled asap. So I did.
Being me I undid the top bleed cap, dropped it. Pissed water over my fingers at 90+ degrees, then switched it off and called the AA. Typically I'd taken my tools out the car the night before, otherwise I had enough water and the stat to do the change completely myself.
Anyway, after waiting for 3hours, the recovery man arrived. I presented him with the parts and the service box exploded diagram, and said "fix it" lol. I did a lot of it anyway, but we swapped the stat and bled it up. It started and was warming up nicely on the side of the road for 10mins. So the mechanic left, and as I started to pull onto the motorway.............................. the temp shot straight back up to 110 again. So I tickled it home and left it.
This morning I packed my tools with the intention of checking it was properly bled up on my way to work once the temp got up.
The temp gauge moved up normally from the stop to 85, then started moving up and down a lot more quickly (I would possibly suggest too quickly for it to actually be the probe responding to variances in temperature...???) I pulled over thinking "oh its just an airlock in the stat housing, bled it a bit more, but water came out prettymuch straight away.
After this, on driving, everytime I touched the throttle, the temp would move quickly from 82 to 90, and then almost immediately move back down on coming off the throttle...
So I nursed it to work at 3krpm and below, and then tried bleeding it again a bit, but no air really came out.
When idling at work in the carpark and bleeding it, I bled the rad top, a bit of air came out, the rad was fairly hot, but when the temp gauge moved up to 110, the fans didnt kick in, and the top rad hose didn't really feel like it was getting hotter or very 'pressurised'. So I unplugged the fan plug again, and the rad got cold almost immediately.
In the course of looking about the engine bay, I have noticed that the bottom (green) plug on the stat housing has got exposed copper wire just where the wires meet the resin mould on the back of the plug...
Having extensively discussed with Ruan yesterday and this morning (who I may point out has been a complete legend dealing with me in varying states of depression agitation and stress), he thinks the combination of the rad almost immediately getting cold when I unplug the fan switch and the fans come on, and the fans not coming on at 110 when plugged in points to the actual temperature gauge not reading the right temperature...??
Does anyone have any experience/ideas with this? I'm a bit lost, and its FRIGGIN un-nerving driving around with the temperature reading all over the place....!
On a complete side note, on the way to work, the engine seemed to develop a misfire at part throttle at about 2.5k, and when planting the throttle it really really juddered. I assume this is likely to be the coilpacks as when the top bleed point went last night, it put a fair bit of water into the recess between the rockers, where it then sat for a good 4hours last night...
