zep Posted November 11, 2005 Share Posted November 11, 2005 As most of you know, I've converted the Gem to a turbo machine. The engine has been worked and now that it's running, it over heats regularly. I initially got a new radiator made, 3 core high efficiency, and replaced the water pump, head gasket and thermostat and that helped a bit, stays at about 1/2 when driving consitently, but sitting in traffic is another story. The 12" electric fan I have seems to be working ok but it just keeps on going up, to almost full temp with idling in traffic. I'm thinking of getting an oil cooler next, which I probably will. Will this help to cure my problem? Turbo is a T3 water and oil cooled, so I imagine the oil is pretty hot after going through the turbo. Any other ideas what might be causing this?

Hemi Posted November 11, 2005 Share Posted November 11, 2005 all i can thinkof is that when the water gets into the radiator its cooling it enough but its not going fromt eh radiator to the engine fast enough ...gets my drift??? , oil cooler would solve this easy i wouldbe thinking , diesel 4wding things have the same problem have huge fan and radiators but the mechanical water pump cant pump water fast enough at idle and the engine ends up cooking itself Quote Link to comment Share on other sites More sharing options...
Guest WESTCORT Posted November 11, 2005 Share Posted November 11, 2005 any room for another fan? extend the radiator piping giving it more capacity, run radiator in boot,,, all i can think of Quote Link to comment Share on other sites More sharing options...
Leebo3 Posted November 11, 2005 Share Posted November 11, 2005 I have heard that by putting your heater setting to hot but not turning the fan on that makes the water travel further. But you don't want to have to rely on this to keep the temp. down. Quote Link to comment Share on other sites More sharing options...

thminiman Posted November 11, 2005 Share Posted November 11, 2005 how old is the radiator, how long has it been in there? it could be something as simple as pipes being clogged with shit, which is a fairly simple thing to fix: empty radiator, get radiator cleaning stuff from repco etc do wat instructions say after that, take drain plug out or take the bottom of the radiator, stik a hose in the radiator filler cap crank the hose and let it go through the system 4 5 mins or so. this might help but if your new radiator hasnt been in the car for very long it might not make much difference Quote Link to comment Share on other sites More sharing options...
lowlancer Posted November 11, 2005 Share Posted November 11, 2005 What's the pressue like through the rad/water lines? You probably want a decent balance between high and low pressure, probably erring on the side of high to allow for decent flow/heatloss. Surely there are heaps of guys in Oz who have done this?

drftnmaz Posted November 11, 2005 Share Posted November 11, 2005 if it was me i wouldn't run the water cooling on the turbo, you dont need it at all, but its sounds like you tune is way out and maybe dentionating a little at idle, what compression ratio do you have? what fuel do you run? the other thing i'd do is raise the rear of the bonnet for a few days and see if it helps maybe the hot air just can't get outta there???? oil cooler is the go and if you can't afford it theres cheap ways to do it.

zep Posted November 11, 2005 Author Share Posted November 11, 2005 Okie.. Well the radiator is a BRAND NEW recore a few weeks ago, so that should be working alright. I'm fairly sure that there is no clogging, I have flushed the entire system about a month or so back when I was running the old radiator. Lowlancer: how do I check the pressure across the rad-tubes? Yeah, the timing and tune is definately out, but I'm thinking that it could be more than just that. Heh, when I put my heater on how it spits out hot air anyway, regardless of wether the fan is on or not. drftnmaz: What's this about not running water lines to the turbo? are they not improtant? If I just take them off and leave the gallery running through the turbo open, will this be fine? Never heard of this before eh. Runing 98 fuel and its very rich at the moment as the carb is playing up. As for oil coolers, I have been looking at at either this: http://www.trademe.co.nz/Trade-Me-Motor ... 341524.htm or this larger one: http://www.trademe.co.nz/Trade-Me-Motor ... 110043.htm I am leaning towards the smaller one as I think it'll be suitable, but if someone could advise, that'd be cool.

Guest WESTCORT Posted November 11, 2005 Share Posted November 11, 2005 you should probly get it tuned first, and then go from there, cause it might be fine once its running mint. Quote Link to comment Share on other sites More sharing options...
droppdkp Posted November 11, 2005 Share Posted November 11, 2005 Yea the heater thing works. Turn it up and the water temp goes down. Definately not cool tho wen its boiling hot and your driving out to the beach. I just washed my radiator out intensley and its working better.

lowlancer Posted November 12, 2005 Share Posted November 12, 2005 I don't know if there's any rwal way to check water pressure, but as you've got a bigger radiator, I would assume it would be lessened. I really don't think it's an issue to be honest I'd get it tuned first man, then as WESTCORT said, go from there Quote Link to comment Share on other sites More sharing options...
TygerTung Posted November 12, 2005 Share Posted November 12, 2005 I'd definatly run the water cooling on the turbo, it's there for a reason and there is a good chance of cooking the bearings if it's not connected. Are you running an electric fan? Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted November 12, 2005 Share Posted November 12, 2005 i don't run water in my turbos, you can just leave the pipes open and its fine. GET I TUNNED!!!! this can cause massive heat. does the turbo suck cold air in or eng bay air? how close is your intercooler to your rad? maybe you'll have to get a slightly smaller pump pully and overdrive your waterpump a bit. btw: how does she drive? my 1800 gem was pretty loose so i imange this must b a little scary in the wet.

coltspeed Posted November 12, 2005 Share Posted November 12, 2005 i'm not using the watercooling on the tc06. i was told by so many different performance shops not to use them but i was dubious un til i was told by mitsubishi also not to use them. the reason is that the turbo gets so hot that when you come to idle after a thrashing and water isn't being pushed through the system as fast is that the heat from water from the turbo cooling starts to overheat the rest of the system. from what i understand it depends on if there is enough oil being put through the turbo to allow you to get rid of your water lines. ask a turbo place if it's ok to run without the water cooling and if it is block them off and go for a drive and see if there is a difference to your temp.

zep Posted November 12, 2005 Author Share Posted November 12, 2005 Yeah, I will be getting it tuned once I sort out my new carby - then make a decision about the oil cooler and shit. I will talk to a turbo shop (can anyone reccommend one in AKL) about not running the water lines and see what they say. drftnmaz: It goes pretty well, despite all the problems, and with the LSD its pretty lethal in the rain Quote Link to comment Share on other sites More sharing options...

I dunno if thats true cos the misubishi cordia 1800GSR Turbo uses a TC06, and they never have any problems. Mitsubishi spent millions of dollars and years of research designing the thing, I doubt they'd miss somthing as simple as that. Quote Link to comment Share on other sites More sharing options...
coltspeed Posted November 13, 2005 Share Posted November 13, 2005 i dunno... i'm just telling what the performance places and mitsubishi told me. Quote Link to comment Share on other sites More sharing options...
coltspeed Posted November 13, 2005 Share Posted November 13, 2005 anyway i'll let you know how it goes cause my car is at boosted performance at the moment getting a couple of things done of which removing the water cooling is one of them as they suggested. if my turbo cooks i guess they will be up for replacing it, something i'm sure they won't want to do.

zep Posted November 13, 2005 Author Share Posted November 13, 2005 Sweet, well I might give them a call and see what they have to say. The car should be tuned by the end of the week so once that's done, i'll reassess the situation, but I'm pretty sure that I'm going to need to go for the oil cooler anyway. Anyone take a look at those two auction? Can ya recommend me one? Quote Link to comment Share on other sites More sharing options...
