after getting my cruiser's cooling system checked out it looks like
I might need an intercooler.
I like the look of the denco, anyone fitted one themselves to a 100 series, any drama's fitting it?
Does anyone know where I'd be able to get a decent second unit from?

Cheers all

Not too sure how these two issues relate. Are you saying that the fitting of an intercooler will keep the engine temps down?

If you are fitting the intercooler for more power then go ahead but if you think the it will keep the engine temp down then I reckon you will be disappointed.
If the engine is getting hot I would be more inclined to have the fuel pump checked and any obstruction to cooling air flow. The 1HZ doesn't suffer overheating problems unless something is wrong. Also check the viscous fan coupling as that was what caused overheating on our 80 series.
Let us know what the results were if you can. Thanks.

Safari highly recommend the intercooler kit to keep exhaust gas temp down. The 1HZ in the 100 series has lighter pistons than earlier 1HZ's (less Al in the top of them), making it more vunerable to damage from high exhaust gas temps. The original 100 series Safari kit was onlyl sold with the intercooler for this reason. They only introduced the turbo only kit due to market pressure.

Another option you have is to get the vehicle tuned on a dyno with a EGT guage attached. This will enable to tuner to check the vehicle is not being overfulled, leading to excessive egt, which may be the cause of you problems. This will reduce the maximum power and torque available but will improve the long term reliability.

I personally have a HZJ105 with the intercooled safari kit. I run an EGT Guage with a buzzer alarm for when the EGT creeps up. If it goes off, I just back off a little until the EGT settles down again. Usually this only happens on long steep climbs at 100 Km/hr. Using backing off to 95 km/hr reduces the EGT back to acceptable values.

You may also want ot investigate fitting a 4 core radiator. This option has been discussed on other threads on this forum if you have a look
