hey peeps as some of you know i arrive in belfast tomorrow at 9 to go see a z what things should i be looking out for things i have so far

 

make sure i hear it start from cold

 

check the ecu for fault codes

 

check for smoke from turbos

 

whines from diff or gearbox and crunching gear changes

 

check rear diff for oil leak check engine for oil leaks

 

check coolant and fan kicks in

 

is there a diy on here that shows you how to check the ecu i know with my celica i bridged two connections with a paper clip and red the engine light flash on the dash

 

body work wise check sills and rear arches front wings secure

 

am sure i have missed loads as i have never owned one before

Check for rust. Even if it's had welding. There are plenty of Zs out there with good bodies (although these are becoming more of a rarity), so don't plump for anything less. They rust around the back of the sills, the floor, the rear aches and the area below the filler cap.

 

Also look inside the boot as they rust right on the very edge of the lip on the inside. Check for leaking main seals (around the front of the gearbox).

 

If it smokes, it could be from a number of things. If it smokes on idle (blue or white) then it'll be turbos. If it smokes on rundown, then that'll be pistons. Intermittent smoking could be PCV related.

 

You've mentioned the fan kicking in. The viscous van should engage from cold start immediately. That's the way to check if the viscous fan is working. Then also run to temp for electric rad fan.

 

I wouldn't be so concerned with ECU fault codes as I would be for anything else. Faulty sensors and dirty contacts are very common in Z32s and aren't too much of a problem to rectify.

 

There's a diagnostics switch on the ECU which is sited beneath the kick plate on the passenger side. You need to turn this on so that the ECU can give you the codes on the dash.

 

Here's a link to a how2 ---> http://www.ttzd.com/tech/diagnostic/diagnostic.html

Also check for seat bolster wear, pedal rubber wear, shifter wear....that indicates a high miler.

exellent thank u
