Basically as the tital says. My rj70 bundera with hzj75 firewall forward (panels and motor changed) is getting to 90 to 95 degrees when going up longish hills or slight uphill at 100kms. Highest temp I've got to has been 97 degrees. Pulled over let it cool down at idle.
Has no issue at speeds under 80kms unless it's a long laboring hill that slows the car down.
Looking for what to test next or pay to get done. as I'm conserned I'll cook it on a long drive.
Things I have done so far:
New upper and lower radiator hoses.
New genuine thermostat.
New adrad 4 core radiator. And cap
New toyota red coolant
Flushed engine block with hose and no thermostat until water run clear. (No chemical flush just water)
Second hand genuine clutch fan off known hzj75 with no cooling issues. (Tested fan when car running at 90 degrees after a hill pull over open bonnet shut off motor and fan stops instant and is tight.)
Removed spot lights from in front of radiator.(No difference)
Removed a.c. condenser from in front of radiator.
No oil in coolant / coolant in oil. Oil is clean
No bubbles in radiator running with no radiator cap.
Not loosing any coolant from system.
New fuel filter and prefilter
New air filter.
New oil filter and oil.
No blow by. (Upside down oil cap check)
Aftermarket temp gauge checked against calibrated gauge and is correct.
Has good oil pressure both factory gauge and aftermarket.
Other changes since the motor transplant from hzj75 at 255kms:
3" stainless snorkel into factory airbox
2.5 " exhaust and extractors with factory muffler.
34" tyres and diff ratio change from 4.11 to 4.3
2400 rpm at 100kms 5th
Is it worth looking into pump / injectors
Or is the problem more likely to be head / pre combustion chambers? Any thing else to check myself before paying to fix? Water pump has done less than 10k. Wanting to turbo once heating issues are resolved.
Thanks all in advance
