Jamesc183 Posted November 15, 2012 Share Posted November 15, 2012 Basiclly got my N/A about 3/4 months ago now and wanted to daily it for a while till i saved up enough for a decent daily (then take it off the road for work). Turns out the guy wasnt the most honest when he said it drives 'Excellant with no problems what so ever'. A few weeks after everytime i go on a long stretch of road over about 40-50mph+ it overheats, So i have to turn the heaters on full blast to get me home and make sure it doesnt fully go into the red. At first I didnt want to think it was the headgasket. But now i do as i found the liquid in the coolant bottle a brown colour. Do I change the headgasket or drop in a whole new 2JZ-GE? What would be more cost efficiant? Being near to christmas i cant afford to drop in a GTE yet!! Thanks in advance guys. JC Quote Link to comment Share on other sites More sharing options...
ripped_fear Posted November 15, 2012 Share Posted November 15, 2012 Depends can you do the work yourself? Remember the GE lump can be had for peanuts, a few hundred notes and you would have a new engine. Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted November 15, 2012 Author Share Posted November 15, 2012 I wouldnt be able to do the gasket change myself on this engine but im pretty sure i could swap it. The only real experiance iv had with this sort of stuff, I know this has no comparison but I swapped engines in my old car (Honda Civic). Is there anyone on here that could do the swap?

Josh Posted November 15, 2012 Share Posted November 15, 2012 New engine would probably be cheaper and easier, unless, as stated above, you can change the head gasket yourself. Check to make sure it is the head gasket first, as the coolant does turn a browny colour if it's old. Sucks about it overheating, though Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 15, 2012 Share Posted November 15, 2012 If its overheated then the head could be scrap if its warped so changing the gasket could well be a waste of time Quote Link to comment Share on other sites More sharing options...
Al Massey Posted November 15, 2012 Share Posted November 15, 2012 Changing a head would be easier than an engine swap no? If you have the tools and equipment we could come to an arrangement for my N/A engine from my current car as I'm building an N/A-T that will be going in my other shell. And I also have a spare N/A head with cams and cam gears if it helps Edit I'm in suffolk Quote Link to comment Share on other sites More sharing options...
hackin_n_bashin Posted November 15, 2012 Share Posted November 15, 2012 Speak to Keron on here, see if he can replace the lump for you, well worth the trip if you can make it, and he can fit you in Quote Link to comment Share on other sites More sharing options...
listy Posted November 15, 2012 Share Posted November 15, 2012 Is it definitely the HG? I had similar on my old NA and turned out I just needed to do a coolant flush, as and replace the rad as it had gone stale and rusty inside. Quote Link to comment Share on other sites More sharing options...

I had similar on my old NA and turned out I just needed to do a coolant flush, as and replace the rad as it had gone stale and rusty inside. Thanks for the replys guys, yeaaa basiclly it overheats on A and M roads, I may try a replacement radiator.. Listy did you have the same results as im having with it overheating? i havent found any whitish colouring looking through the oil cap yet? Ill get some pics up soon for you guys to have a look at.

FOSTA Posted November 15, 2012 Share Posted November 15, 2012 If I was you, I'd look at the thermostat first, then do a full coolant flush and check the radiator. The chances are its somthing simple. Might even be worth checking the temp sensor as that could be dodgy! Good luck Quote Link to comment Share on other sites More sharing options...

JC I did dude. Mine was gushing water onto the over flow and bubbling like crazy, with the temp gauge rapidly approaching the red. Did a full flush, and all sorts of brown coolant with rust in it came out. Replaced the rad, job done. Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted November 15, 2012 Share Posted November 15, 2012 Have you had the coolant tested for fuel/exhaust gases? if not do it. Or buy the kit to do it yourself. http://www.ebay.co.uk/itm/UNIVERSAL-BLOCK-TESTER-KIT-FOR-GASKETS-CYLINDER-HEADS-PETROL-DIESEL-BT500-/140884673940?pt=UK_Diagnostic_Tools_Equipment&hash=item20cd618594 Quote Link to comment Share on other sites More sharing options...
keron Posted November 15, 2012 Share Posted November 15, 2012 If you need an engine or supply and fit let me know... But could be water pump? Blocked rad? Faulty viscous fan etc etc... Quote Link to comment Share on other sites More sharing options...
Jamesc183 Posted November 15, 2012 Author Share Posted November 15, 2012 (edited) If you need an engine or supply and fit let me know... But could be water pump? Blocked rad? Faulty viscous fan etc etc... Thanks for the that keron! Could you pm me a rough price to swap in an N/A? Ok so i got a thermostat & a new rad cap coming. Gonna order the new rad tommorow too and hopefully ill find out whats going on! Would i be able to even check if the rad is bad if i looked in it by taking the cap off?

Chris Wilson Posted November 16, 2012 Share Posted November 16, 2012 Oh dear, that is madness, and it's the sort of madness I am seeing a lot of. If you took the car to a proper professional they could tell you for sure what was wrong with it, as they'd have the right gear to find out. Why do people throw expensive bits at an unknown issue in the hope it *MIGHT* just fix it? I could tell you if there were combustion gasses in the coolant using two totally different methods in ten minutes. A coolant pressure test another ten minutes. Doesn't have to be a Supra specialist, we are just talking cooling issues on an internal combustion engine..... Quote Link to comment Share on other sites More sharing options...
