revs dropping ryt down almost cutting out

Engine off, pull the fuse, leave for 10-20 seconds, put fuse back, start the car. This will reset the ECU and clear all stored CEL codes.

Remove the clock/radio ruse (#43 in the below pic) for 10-20 seconds from the engine bay fuse box.

Honestly bud, you need to bleed the coolant system through.

[NafemanNathan]

You don't have to drain the whole thing, although it is recommended to replace the coolant every 2 years regardless of the mileage.

There's a bleed valve on the thermostat housing. Coolant needs to be oozing out of this bubble-free when it's open and the engine is running.

This is the link I gave you before, have a read through for some pointers...

No problem.

If it hasn't completely sorted it, there's probably a bit more air still in there. Run it until it's hot a few times and squeeze the rad pipes (top and bottom) to dislodge any more trapped air.

Good oh

[indigolemon]

Does the temp go above the halfway mark?

[NafemanNathan]

How long are you waiting? Mine sometimes take a good hour to kick in if it's just left to warm up. Depending on how cold it is they might not kick in at all

[indigolemon]

What does the temperature gauge say though? Is it overheating? My fan doesn't really kick in unless I'm sitting in traffic.
