Running hot?

[VX KAT]

I started to develop that same pattern of overheating.
New thermostat, no change.
Decided to go with a larger all aluminum custom radiator. Greatly improved, but didn't solve.
Had read that several owners had recently had the fan clutch go and once replaced, all overheating resolved.
So I replaced fan clutch, which Isuzu had redesigned, and now requires a new fan blade too….TOTALLY RESOLVED ISSUE, TOTALLY!!
So like etlsport said - sounds like might be fan clutch.


There were several threads and lots of discussion on the topic over the last 18 months:

After the engine reaches normal operating temp, the intake is supposed to switch from pulling air from the warm engine compartment to pulling it from the cool wheel well.

Maybe the damper on your intake is blocked or perhaps your cold air intake is clogged. Pull out your airfilter (& replace if dirty) and check around in the airbox to make sure all is well in there.

On the other hand, maybe it's time to consider installing a snorkle kit
