Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 Hi all. I have a 1993 non turbo supra vvti and it's using a lot of water. I put a new radiator in and new top and bottom radiator hoses and a new thermostat but it keeps using water. It uses around 2 liters every 3 days or so. Any help or ideas will be welcome thanks Quote Link to comment Share on other sites More sharing options...
Al Massey Posted August 15, 2013 Share Posted August 15, 2013 What coolant are you using? And to what ratio with water? Quote Link to comment Share on other sites More sharing options...
Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 At the min it's just a cheap brand coolant and as for ratio ain't got a clue on that on. I see it as long as it has it in then it's all good lol. Didn't think having the wrong ratio could make you lose water. Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 15, 2013 Share Posted August 15, 2013 (edited) Check for leaks and if you can't find any get a sniff test done for exhaust gas in the coolant Check the passenger foot well incase the matrix has a leak but 2 litres in such a short time should be pretty obvious as the system only holds just short of 10 Was it okay before you changed the rad and hoses ?

Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 Had a sniff test done that past. No gases in the coolant at all. Inside the foot wells are bone dry. And I can't see no leaks at the front of the engine or around the pipes or water pump. All the heater pipes are getting hot the fan is working. The heater in the car blows hot air out and I can not smell any gases thought the heater. Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 15, 2013 Share Posted August 15, 2013 You could get a garage to do a coolant pressure test on it. Do you have an expansion tank ? Has this problem started since you replaced the rad etc ? Quote Link to comment Share on other sites More sharing options...
Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 It has a mother bottle for coolant only. The problem started about 4 months ago I put the new radiator it about 4 days ago. So it's a on going problem really. - - - Updated - - - Another not mother lol Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 15, 2013 Share Posted August 15, 2013 (edited) Whats a mother bottle ? LOL It can only be one of a few things It has a leak somewhere It is losing it via the combustion cylinders Block or head has a crack Coolant is pushed out the rad via the cap when hot to the expansion tank but not drawing it back in when it cools Did you fit a new stock pressure rad cap ?

Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 Another that was ment to be lol Quote Link to comment Share on other sites More sharing options...
Al Massey Posted August 15, 2013 Share Posted August 15, 2013 Have you checked the coolant pipes at the throttle body? I had a leak there once. Quote Link to comment Share on other sites More sharing options...
Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 I've checked all pipes that I can that hold water and there is nothing dripping no splits or anything but I will have another look Quote Link to comment Share on other sites More sharing options...
Josh42 Posted August 15, 2013 Share Posted August 15, 2013 Check all the coolant hoses. The one at the back of the block on mine had split. Also check the core plug on the back of the waterpump isn't leaking. Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 15, 2013 Share Posted August 15, 2013 I would get a pressure test done on the cooling system Check page C0-18 in the attached pdfCO.pdf Quote Link to comment Share on other sites More sharing options...
keron Posted August 15, 2013 Share Posted August 15, 2013 as josh said... common places to leak on the na... and you cant always see it..... core plug on the back of the waterpump housing, the 2 pipes from engine to bulkhead/matrix.... where they clamp to the engine mainly.... best to get it on a ramp, run it while its in the air and inspect it for leaks.... to loose that much water, it must be a leak...if it was a hg problem, it would run right for long periods....

Digsy Posted August 15, 2013 Share Posted August 15, 2013 When you say its losing coolant, is the level dropping in the expansion tank or the radiator itself? Does the level in the expansion tank rise when the engine gets warm and drop when it cools back down cold? Quote Link to comment Share on other sites More sharing options...
Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 It loses it out the tank and the radiator. So all water and coolant are being lost as for the coolant level getting higher and lower I don't no. It has the standard radiator cap on it.

imi Posted August 15, 2013 Share Posted August 15, 2013 have you tried replacing / changing the radiator cap? Quote Link to comment Share on other sites More sharing options...
keron Posted August 15, 2013 Share Posted August 15, 2013 yes try changing the cap (oem one genuine) also has the system been blead properly? poss an airlock? Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 15, 2013 Share Posted August 15, 2013 Does it overheat? Quote Link to comment Share on other sites More sharing options...
Digsy Posted August 15, 2013 Share Posted August 15, 2013 It loses it out the tank and the radiator. So all water and coolant are being lost as for the coolant level getting higher and lower I don't no. It has the standard radiator cap on it. If there is an engine leak then the level in the radiator might drop while the engine is cold, and certainly will when it is hot (but you can’t check the level in the rad when its hot). When the engine cools it should draw coolant in from the expansion tank to replace the lost coolant, so the level in the tank will drop when the engine is cold, but the level in the rad should be full. This will carry on until the engine has lost so much coolant that there isn’t enough in the expansion tank to replace it, at which point the expansion tank will run dry. If you top everything up (rad and tank) then get the car nice and hot and then park up you should be able to see if the levels in the expansion tank are behaving correctly. Then you can check the rad and expansion tank again after it has cooled down. That may help you pinpoint where the leak is coming from. Normal behaviour is: Check before test / cold: Rad full and tank up to full mark. Hot: Tank above full mark. Cold: Tank back down to full mark. Rad full.

Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 It does over heat only when there is no water or coolant in the system. I only let that happen the once I always keep a load of water in the boot. Some days the rad is full and the tank empty. Some days it's bang on as in rad is full and tank is on full mark. Some days rad empty and tank on full mark. Quote Link to comment Share on other sites More sharing options...
dan294 Posted August 15, 2013 Share Posted August 15, 2013 I'd stick an OE Rad Cap on from Toyota, worth a try for the price of them. Before fitting the rad cap, get it bled up properly. Quote Link to comment Share on other sites More sharing options...

Guest Bumblebee25 Posted August 15, 2013 Share Posted August 15, 2013 Water in the rad and coolant in the tank. It's starting to cost more to keep it cool than it is to run lol. Quote Link to comment Share on other sites More sharing options...
Al Massey Posted August 15, 2013 Share Posted August 15, 2013 Water in the rad and coolant in the tank. It's starting to cost more to keep it cool than it is to run lol. Right, the water could be boiling off. Drain the whole system completely, then top up with the coolant and water mixed. As said the coolant from the expansion tank only gets drawn in when it's cooled down. The water will most likely be boiling and evaporate.
