Dirty milky slime green old coolant dumped from the gold 240 wagon: https://twitter.com/FredCookeNZ/status/ ... 8613841920








And flushed through with water twice (yet to dump the second lot) and hoses off to clean around the fittings which were a bit crusty: https://twitter.com/FredCookeNZ/status/ ... 5196538881








It's not often that I use the HDR feature of the N5, but when I do it's because of excess contrast in a tstat housing. :-/

Will pull the drain cock on the block in the morning and dump it out fully before refilling with a nice 35% blend of fresh nulon coolant. Yay.

Forgot to take a snap of the cleaned up housing, but it doesn't matter much, that SOHC head is on borrowed time :-D

Fresh coolant in after another flush and a proper drain through the drain cock I didn't know these engines had: https://twitter.com/FredCookeNZ/status/ ... 0674894848










Next coolant change: In with the DOHC setup :-)

Not much maintenance in some time, but a bunch due now or soon. Got started last night with the Stagea, now running high-end pure PAO/Ester group 4/5 synthetic Penrite oil with lots of zinc and no shearing effect. So I want to get bypass filtration onto it, and the others, so can leave the good oil in 20,000km instead of a mere 5000km, as that seems like a waste for something that doesn't really get degraded by use.

Processed used, and mileage done at:

You may notice the difference between cambelt done and current kms on clock... and it's making a slight noise... so I'll be doing that soon. Damn it.

Also, ATF has been working hard recently and needs to be flushed and filled with good synthetic ASAP. Was red, now reddish brown, smell is not full burned, but it has been hot, that's for sure.

Stagea ATF flushed through, same mileage as above, tweet tweet: https://twitter.com/FredCookeNZ/status/ ... 7130670080

Saturday:

240 and 740 both populated with Penrite PAO Ester 10w60 true synthetic (not like Mobil1 junk, cough cough). And a spill, oops.

Two more cars needing bypass filtration!

Sunday:

Speedo fix for 740
Cam belt inspection session on Stagea (OK!)
Crank angle sensor fix on 940
Caravan lightweight axle progress

Going oil shopping tomorrow:

5 * 40 = 80w140 pro synth diff oil (all RWD diffs)
10 * 60 = 15w50 or 20w60 PAO Ester engine oil (full zinc/ZDDP)
2 * 40 = 70w75 GL4 Plus pro synth mtx oil (Volvo 360 and KP J160)
2 * 40 = 75w90 GL4 Plus pro synth mtx oil (ute/rx7 box)
150 = 20l of ATF FS for stock
70 = Another 28 cans of degreaser
60 + 20 = 5l + 1l of 15w50 or 20w60 PAO Ester engine oil FOR ROB/R33
2 * 40 = 2.5l + 2.5l of 75w90 GL4 Plus pro synth mtx oil FOR ROB/R33
40 = replacement diff oil from ROB for me :-)

200 + 600 + 80 + 80 + 150 + 70 + 80 + 80 + 40 = 1380 - 200 (Rob) = 1180

Or something like that.
