cheekymonkey Posted January 17, 2008 Share Posted January 17, 2008 After a spirited drive just now, I notice a small amount of smoke/vapour coming out of the bonnet, I open it up and there's a bit of coolant around the radiator area. Switch the engine off and it hisses like a very large hissing thing, steam spewing everywhere from the top rad pipe. It calms down and I reckon I've lost less than half a litre of coolant. Peak water temperature during my run was 94 degrees, temperature about 5 mins after turning the engine off was 110 degrees. Do you guys reckon I'm safe to clean up, top up and tighten hoses?

Dave F Posted January 17, 2008 Share Posted January 17, 2008 I may be wrong but should'nt the coolant be the toyota red forlife rather than the green forlife. Quote Link to comment Share on other sites More sharing options...
CarlT67 Posted January 17, 2008 Share Posted January 17, 2008 Yea I would say so, may require a quick bleed. I remember that my coolant temp rises after shut down as the fan is not drawing the cold air nor is it being 'rammed' through and the water is just heated by the block. Should only rise slightly though I think.... Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted January 17, 2008 Author Share Posted January 17, 2008 I may be wrong but should'nt the coolant be the toyota red forlife rather than the green forlife. Well our very own CW did it so hopefully it's the right stuff. Quote Link to comment Share on other sites More sharing options...
Dave F Posted January 17, 2008 Share Posted January 17, 2008 Its also worth having a good look for a split on the hose or a crack in the rad, maybe underneath out of sight. Quote Link to comment Share on other sites More sharing options...
Dave F Posted January 17, 2008 Share Posted January 17, 2008 Well our very own CW did it so hopefully it's the right stuff. He could have tightened it up a bit better though *grin* I certainly would'nt doubt it if Mr Wilson had done it. Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted January 17, 2008 Author Share Posted January 17, 2008 Its also worth having a good look for a split on the hose or a crack in the rad, maybe underneath out of sight. Will have a look, but I think it's just where the blue hose has popped off slightly - the brown bit never used to be visible. Quote Link to comment Share on other sites More sharing options...
Nic Posted January 17, 2008 Share Posted January 17, 2008 I'd remove the hose, clean up any residue where it seals onto the radiator, put the hose back on making sure it is tight and refill the coolant. Perhaps also replace the rad cap if it old and make sure where it seals to the rad is clean. Leave it ticking over for a while to bring the temps up and see if it is leaking anywhere. Hopefully it was just the connection for the pipe that was loose and causing a pressure drop in the cooling system making the coolant boil over and blow the pipe off.

cheekymonkey Posted January 17, 2008 Author Share Posted January 17, 2008 Thanks Nic I will have a go with that tomorrow, Im confident it's not a big deal Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 17, 2008 Share Posted January 17, 2008 Put a stock rad cap on it mate! The aftermarket ones that raise the pressure are bad IMO and funny enough alot of the cars i have seen with a blown heater matrix have one fitted.

cheekymonkey Posted January 20, 2008 Author Share Posted January 20, 2008 Hey all Just taken a look and found my problem (see attached pics) Question is, can that be fixed with a part or is this the Supra Deity's way of making me uprate my whole rad?

AndyT Posted January 20, 2008 Share Posted January 20, 2008 Looked in the manual mate and couldn't find a part. It does look as if you can get a spanner on those flats which would infer that that broken pipe will screw out and that you could replace the broken pipe. Hope so bud.

cheekymonkey Posted January 20, 2008 Author Share Posted January 20, 2008 Thanks for looking - the flats seem to be cosmetic and CW advises I need a new rad. Oh well Anyone have any thoughts about which rad to go for? BPU at the moment with future mods one day including going single. Quote Link to comment Share on other sites More sharing options...

Seen some Fluidyne's on here recently. Will have a shufty mate. Quote Link to comment Share on other sites More sharing options...
AndyT Posted January 20, 2008 Share Posted January 20, 2008 Hmm. Thought there was more but Envy has Koyo for a reasonable price.. http://www.mkivsupra.net/vbb/showthread.php?t=122764&highlight=radiator Not as cheap as PHR as you know but at least you'll get it quickly. If you do, I'd stick to the 1 bar rad cap rating for now. Quote Link to comment Share on other sites More sharing options...
Nic Posted January 20, 2008 Share Posted January 20, 2008 Anyone have any thoughts about which rad to go for? BPU at the moment with future mods one day including going single. The best radiator available for the Supra IMO is the Power Enterprise Double row, not the cheapest, but much better than my old Fluidyne.

cheekymonkey Posted January 20, 2008 Author Share Posted January 20, 2008 Cheers guys, I will have a look at some. How do you know what's a good one, or not?

Thats where mine broke off. I turned an aluminium tube that was a perfect fit and locked into the rad. Also glued in with Araldite. Been on there about 8 months and no leaks or drips at all. Saved buying a new rad. If your interested I could send you the drawing of the part or make one up for you. Quote Link to comment Share on other sites More sharing options...

Hey mate that's much appreciate, shows the club spirit is alive and well However I will have another look today, and may end up getting a new rad anyway as mine is quite tired. My water temps at SRR were quite high during the mapping session so the upgrade was on the cars already Cheers james Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted January 21, 2008 Author Share Posted January 21, 2008 Have just ordered a new Rad. It's from CW and it's a brand new unit that uses the stock plastic end caps (sorry no Bling:)) with an updated alloy core that's more efficient than stock, and is also cheaper, as a bonus!

cheekymonkey Posted January 21, 2008 Author Share Posted January 21, 2008 Hey all just a quick one. I've secured the hose as best I can, and I've topped up the rad, it took about 1.5litres and put another 500ml or so in the expansion tank. I then ran the engine until it got to just over 80 degrees, no visibile leaks. How do I bleed the system? PS I am not going to be driving hard until I get the new rad, but the top hose does seem pretty secure at present Quote Link to comment Share on other sites More sharing options...
