Hope you stay ok.
Love your videos, thanks.
97 Japanese domestic import, Isuzu wizard ucs69, lwb. 4jg2 turbo diesel 4wd. 250k. Bought it 2 1/2 years ago. Fixed a bunch of stuff. It goes ok. Clean exhaust, starts fast.efi pump. all stock standard.
I do a couple of weeks of 1-2 low ratio 5000' full load 60 minute convoy climb, park then descend mountains in mid summer.
sometimes at 35°c (95f) ambient.
Rest of time 50% highway 50 town -5 - 35°c.
Temp gauge sits at 45% untill last ten minutes of hill climb, temp will climb through 60% then I have to turn the AC off and roll down the windows.
Within a couple of minutes it's back down to 50%.
Since then I topped up the viscous fan as I wasn't hearing fan roar.
Head gasket failure prevention.
In the time I've had it,
New Chinese larger single tube radiator (feels like quarter the weight same fin width ) & I'm told it's higher heat transfer to atmosphere than original,
additional larger trans cooler ( in series with radiator ),
W pump, viscous silicone top up, thermostat & antifreeze & regular washing fins.
Should I put a heat gasket sealant in now or carry if it fails?
Will it reduce the coolant system heat transfer performance?
If the sealant is in for say 3 years, Does it loose it's sealing effectiveness ?
If I can't get steel seal here in New Zealand, got any others you tried?
Thanks Scotty, keep on telling it like it is.
