supra_ufo Posted May 3, 2013 Share Posted May 3, 2013 My MOT happens to be tomorrow so I was giving the car a visual once over, and noticed that it was leaking coolant from underneath the car! It appears to be coming from the passenger side above where the sensor goes in. See picture. The tube on the left is the bleed valve and tube. Is it new radiator time? There has been no leaks from here before, seems to be coming out more once the car gets to 90c. Quote Link to comment Share on other sites More sharing options...
LOGIE Posted May 4, 2013 Share Posted May 4, 2013 has the sensor been remover lately? might just need tightened. Would a rubber washer not stop the leak? Might be worth a try before buying a new rad. Quote Link to comment Share on other sites More sharing options...

Shane Posted May 4, 2013 Share Posted May 4, 2013 Looks like there is signs of coolant around that whole area. It will always find it's way to the lowest points and drip from there so may not be from the drain plug at all. Have a real good look around all over the rad and confirm where the coolant is coming from before jumping in with rad replacement. Quote Link to comment Share on other sites More sharing options...
Dnk Posted May 4, 2013 Share Posted May 4, 2013 (edited) If its the original rad its more than likely done its day, you could try removing the sensor and re fitting it with a new seal or sealer to rule that out before buying a new rad just in case its that.

Guest pcbl Posted May 4, 2013 Share Posted May 4, 2013 You can get the rad rebuilt, which should be cheaper than getting a new one, had one rebuilt for £60 in 2004 for a different smaller car. Should cost a little more these days and supra has a larger rad. Search radiator repair, I went to the one in Birmingham Digbeth area.

supra_ufo Posted May 4, 2013 Author Share Posted May 4, 2013 Sensor has not been removed....I went to the MOT centre they had a look at it and said its screwed, it was coming from the sides, they told me to fix it and come back for an MOT lol. They suggested to have it refurbed too. I might take it off tomorrow and take it to a refurb place on Tuesday. Failing that what do people suggest apart from OEM which will be very costly. Are the alloy ones any good? Fleebay sell some, I know SRD sell them too but I would also need a gearbox cooler as mine is an auto and we are talking £300+... btw, drove the supra for the first time ... It was niiiice. There was a lot of whistling and hissing going on which is normal?? I obviously wasn't ragging it due to the leak. Quote Link to comment Share on other sites More sharing options...
Dnk Posted May 4, 2013 Share Posted May 4, 2013 I'd imagine the hissing is the coolant leak and advise you get it fixed rather than drive it, normal driving is as bad if you have a coolant leak as the water temp will still rise along with the pressure and you will just keep losing coolant. The mkiv has an aluminium alloy head and if overheated can warp and become scrap very quickly Quote Link to comment Share on other sites More sharing options...
LOGIE Posted May 4, 2013 Share Posted May 4, 2013 Spend £300+ and buy genuine is my advice. Costly but worth it in my opinion. Quote Link to comment Share on other sites More sharing options...
LOGIE Posted May 4, 2013 Share Posted May 4, 2013 www.readyrads.co.uk Have you used them before Dunk? I wonder if they could do my smic? Quote Link to comment Share on other sites More sharing options...
Dnk Posted May 4, 2013 Share Posted May 4, 2013 Have you used them before Dunk? I wonder if they could do my smic? I have used them for radiator re cores and they have always done a very good, not had an intercooler done though, they could be worth giving a call and see what they say Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted May 6, 2013 Author Share Posted May 6, 2013 as you can see, pretty knackered.. I am just torn between an OEM or one supplied by SRD+a auto cooler, prices are similar. Quote Link to comment Share on other sites More sharing options...
Rich.2211 Posted May 7, 2013 Share Posted May 7, 2013 On a side note, have you checked the condition of the front cross member the radiator sits on? I've heard stories of these going pretty rotten on Supras with leaking radiators as the water must drip down and rot it away. Infact I think DNK had his replaced on his black Supra that recently sold? Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted May 7, 2013 Author Share Posted May 7, 2013 i'll check it out, Im fairly sure its only been leaking from the bottom so wouldnt effect the cross member, but then again I have no idea where the cross member is on it lol Quote Link to comment Share on other sites More sharing options...
Dnk Posted May 7, 2013 Share Posted May 7, 2013 (edited) Its directly under the radiator, it also rots without the rad leaking onto it. Edited May 7, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted May 8, 2013 Author Share Posted May 8, 2013 Mine seemed pretty good dnk. I have replaced the radiator and all seems well under the car, went to the petty station which is about a mile drive....as ive only been in a supra once my car sounds scary for a stock engine, and I am unsure if i have a problem or not. When in boost, cruising between 30-40, i think around 3k RPM (when ever the turbo kicks in) it just makes a whinnnnnnnnnnnneeeee noise, sounds like when you have a vacuum cleaner on and you cover the end just leaving a slight gap.... I need to take a video of it really but surely this is not normal? Also this whine noise must be heard from outside as as driving some girls turned to look (my exhaust is stock), either that or they were slappers lol My uncle said that its always made that noise, but I dont believe him considering he said the front indicators were fine and after a 4 page thread it turned out to be the wrong front bulb/wiring.
