Tonights task after a moderatly positive day at work was to remove the old throttle body , split the IACV from it and refit all the gubbins onto the new TB.
Throttle body conviniently placed here at the end of the ITG filter
5 million pipes removed. Various fittings were taken off and sworn at as every single time I needed the other socket. 7mm this time Sir? You will need the 6mm for this clip.
A single 12mm and 3 13mm nuts and voila. TB off. Someone has been here before me and bodged it. Why is one a 12mm? Why is one a threaded bar and the nut is stuck to it to clamp it down? Pretty sure the thread should stay in and the nut comes loose…
Anyway , its off. I plugged up the two water pipes underneath with some of the finest bolts known to man from my spare “Renault 5 GT Turbo spare bolts” tin
Lets grab the tape measure just in case I already have a shiny new 70mm TB fitted and I just wasted my money. Pictures dont do it justice and I dont have a vernier gauge. Its 65mm on the top TB and 70mm on the bottom new TB.
At this point I gained a supervisor. To be fair he is less hairy than some of the supervisors I have had before.
Now here is the money shot. Old TB stripped and new TB with the bits on.
I must confess I had fun with two parts.
- the spring loaded twisting mechanism to return the TB back to “stop”
This was a riot. I undedid the screw gingerly and then oh so gently tool off the quadrant. Cue a spring doing the great escape and flinging its way 1/2 way across the garage into the spider wastelands. I did debate just ordering a new spring from Toyota and let the spiders have it. However I took a brave pill and got the spring
- The IACV screws.
I knew these would be a bastard to get out. My screwdriver(s) would not dig into the slightly knackered posi head. Someone had been here before so I ended up drilling the heads, slipping about a jillion times and wacking the heck out of it with a cold chisel. Got there in the end. Not my finest work but unless you are John you wont see it. Changed the gasket over on the IACV , cleaned up the IACV and put in three new Toyota screws. I noted that the IACV had a magnetic part to it. I found this out as all the swarf was stuck to it. Cue more cleaning.
