1JZ-GTE Soarer Temp Issues

[ONETEN]

You should put thermostat back in. That is why it takes ages to warm up. Stock thermostat starts to open at 82 and fully open by 92.

My car sits on 86deg on the highway and about 92 when stopped and in traffic.

If you want to check for BHG, take it to mechanic as they can do it in about 2 seconds and it should only cost $20 or so. I got mine checked the other day on the dyno as the microtech was saying that it was getting very hot but it turned out to be a ground issue.

Slightly off topic, but is your car manual or auto? What igniter and coils are you using? Is the ecu a v4 or v4+?

Thanks

Chris

Chris,

i installed the wolf and i started that thread that yourself and 1jz-747 were most helpful in. I got the bastard runnign well without a filter box (the filter box actually made things worse) we ditched the whole factory ignition and installed a 3 channel haltech ignitor with three haltech dual outlet coils to run watse spark, and she runs OK. It is v4 not plus the standard v4 has two trigger inputs now not just one anymore. Both the v4 and v4+ have two now. Id say the problems you had with your wolf were just due to incorrect wiring cause in theory there shouldnt be any problems running the factory igintion.

Cheers for your help mate and if you hear of anyone with 1j or 2j & wolf troubles send em my way and i will try to help.

Will do mate. Thanks for the explanation.

Ran the car last night, took it for a little drive. It went from 0-115degrees quicker then what it went 0-115km/h. Now im thinking there is something terminally wrong with the engine, doing a TK Head test today (Device used to sense carbon monoxide inside the cooling system) and will see if it has a blown head... I'm stumped

did it boil? (water out the overflow etc?)

was the core of the radiator hot?

[chris davey]

didn't change any wiring to the water temp sensors? Mine shoots up to 120deg when I boot it but I think it is because of the grounding of the water temp sensor

There wasn't any water boiling out the overflow, and yes, the radiator was extremely hot.

[SL666]

thermo fan kick in etc?

well water pump works, thermostat is opening, but at 120 with no coolanet (or actually even with) it would usually be boiling its ring out..

might be worth putting a multi meter on the temp sender and checking it against its specs if you can?

was the heater blowing super-hot air etc?

We've changed both temp sensors, checked and checked again. Will get my mate to check with a multimeter, but everything is working as far as we know. Yes, fan is blowing super hot air as well.

just out of interest, whats telling you its 120 deg?

I bought a external temp gauge, which came with a sensor, which is what its reading off. There also is a temp readout on the Wolf 3D Hand Controller.

thermo fans only really help at low speeds.

Checked radiator cap? I don't see why the radiator is getting very hot but not going into overflow?

Also, if you have the car running and fill the rad slowly see if it start to push back up the outlet quickly. If so, the rad may be blocked.

To check for blocked fins, you can pull the rad out. let it cool and then poor in boiling water from a jug and run your hand across the fins to check that each tube is getting hot. If one tube stays cold at the bottom then it is blocked.

When it got really hot did you get out and check the thermo fan was definitely working?

[chris davey]

and was the thermo fan pushing or pulling air the right way?

[ae86dave]

chris davey has a good point what way do you fans spin?it could be blowing hot air into the radiator if there blowing not sucking.does it use alot of water?are there any other problems?

[beasht]

thats the mistake i made as embarassing as it is just fudged the wires back to front, had hot air from the enginebay being pulled thru the radiator. swapped the wires back to how they should be and overheating probs are gone
