how to keep my 2H motor running cool

[chomper]

i have just bought a 1989 model landcruiser with a 2H motor. the person who owned it before me installed an after market sprintex super charger. the motor runs a little hotter than it should i want to be able to tow a boat and want the motor to run cooler what is the best way to achieve this.

had he had the fuel pump adjusted to suit ?

it may need tuning with the apropriate diagnostic gear

Did you know how much boost it run .. and how much EGT get ?

Already Flush the rad and check the rad cap .. ?

Not sure i have spoken to his mechanic in canberra he is sending me all the info of what they did with the motor. the radiator looks brand new i got told by a mechanic today that it could be the clutch fan. he said he would put a new clutch fan in and put a cooler thermostat in, between $600-$700 would that fix the problem and does that seem like a fair price

No i don't how can i find that out. what do you mean by EGT. The radiator looks brand new filled with coolant. i was going to get the radiator flushed and check the thermostat. The only thing is the guy i bought it off spent quite a lot of money on this car and the motor and if that was all that was wrong with it he would have got it done

EGT is exhaust Gas Temperature, and is essential in correctly tuning a diesel.

Layto....

egt = exhuast gas temperature

to see if the eng is over fueling or under fueling , basically to see if it is in tune

try the thermostate as its cheap n easy to do

is it hot all the time or only when u give it a hard time ?

600 - 700 AUD ..?

Check the fan clutch it's really easy .. at mornings engine totaly cold it could be free ( move with the engine stop with one finger ) and at hot engine ( normaly running temp ) it must be " locked " or acopled.

It meand you can move with the hand or at least hard to move ..

PD blowers create high intake air temps, from that comes high engine and exhaust temps, you may have to turn the fuel down to cool it down. You can fit an aftercooler, water to air is generally easier with a PD blower, you can fit air to air but its a lot of work including raising the blower significantly enough to get air in and out.

it only got hot going up some hills when i drove it down from Canberra. Since i have been driving it around town it hasn't got too hot but it is running hotter than it should. I have it booked in to a mechanic on Tuesday, i will get him to check the EGT, the thermostat. and get the radiator flushed.

Don't worry i'm not seeing the mechanic that gave me that quote

where abouts on the Peninsula are you located. do you have a workshop there, trying to find a good four wheel drive mechanic might of found one in Cranbourne but not sure how good they are

test 1

1. engine cold
2. you can move the fan ( fan clutch disengaged ) free ( with one finger )

test 2

1. engine at operative temp
2. carefylly try stop it with engine at idle or stop the engine and try move it and it will be hard to move ..

better ..
