Getting Very Hot!

[Guest 40th-edition]

driving back from tamworth today the line was getting very hot and not stopping rising so every hill i coasted down and kept her cool, limping it home.

never had this problem before!! but never done a really long trip in this hot weather that we had today.

anyone else have this??

i know intersooler blocks more than half the radiator but never before been this hot!!??

cheers, Azza

Is your cooling system bled properly?

[paulr33]

check coolant levels, maybe do a full flush

half way on the stock guage is around 80 deg which is fine

[Guest 40th-edition]

coolant level fine, was going to give a power flush at work tomorrow.

bled fine because havnt changed coolant or level is same as always,

cheers

how far up was the needle getting?

[Guest 40th-edition]

well it was almost hitting that line just before H

probs would have went all the way, started cutting out aircon and stuff!

[paulr33]

yeah thats no good, if it does it more mabe water pump is shagged, have seen the blades on a water pump basically perish on an rb30e and it had a similar problem, just hot as all of a sudden. was only when they pulled the water pump out they found the blades on it were non existant

Thermostat?

Did the temp start goin down as soon as you let it coast or did it take a while to go down?

[mad082]

was the clutch fan working?

i'd also check the thermostat.

a good idea when the clutch fan kicks in is to drop back a gear to get the revs up higher. this pulls more air through the radiator. works good around town, you just have to put up with the roar of the fan.

mine peaked at 96deg in traffic with ac on (thanks ECUTALK Diagnostics), turned the aircon off and cruised through the traffic and she went below 90 in no time

If you were running A/C, I'd be looking into the failure of the fan (out front of A/C radiator). Check the thermo switch, located in bottom radiator tank) is still functioning.

cheers heaps guys..

i know the water pump is good, got changes 20k ago.

thurmostat is good due to correct warm up and running temps.

i was going to check that little ac electric fan in front of the condencer... see if its working. but it was down the h/way at 100-90 so i didnt think the fans would come into play so much!

the viscus fan is working fine, checked that right away.

do the alloy tank radiators run cooler at all from the standard plastic

ones??

thanks again, azza

i have a just jap cooling pro radiator, and my engine runs between 74-78 degrees, peaking out at 80 - 82 on a hill climb with 10mins of hard driving on boost.....

----could be a head gasket.

Could be radiator needs to be taken off and new end tanks and flush etc., ac fan has nothing to do with it.

not head gasket, already tested with TK tester.

i think its just fricken hot day and FMIC blocking up most of the flow
