SteveR Posted July 24, 2009 Share Posted July 24, 2009 What temperatures (water & oil) are you seeing, specifically? What gauges are you using - the OEM water temp guage doesn't represent a uniform reading. Quote Link to comment Share on other sites More sharing options...
Guest JDMDOM Posted July 24, 2009 Share Posted July 24, 2009 right now i'm susing the hks 60mm gages they are pretty acurate. normal temp on the gages are 7, the water temp stay at 7 wile the oilt temp goes to 8 and up. after driving the car for 20 min or so the water temp start going up to 8 and 8.5 and the oil temp goes up and down betwen 8-9 that's just driving it easy like a VW polo LOL Quote Link to comment Share on other sites More sharing options...
SteveR Posted July 24, 2009 Share Posted July 24, 2009 what does 7/8 etc mean in real terms (degrees C)? Quote Link to comment Share on other sites More sharing options...
Guest JDMDOM Posted July 24, 2009 Share Posted July 24, 2009 to tell you the true i have no clue, is about 3/4 of the way up on the gage! Quote Link to comment Share on other sites More sharing options...
Missile Posted July 24, 2009 Share Posted July 24, 2009 Is your water pump working correctly. Seem's odd its ok on tick over but when your driving it it get's hotter. Unless a belt is slipping. Are you driving it hard when you say your driving it ? Unless some underlying issue is up. Seems really odd the oil temps going up. Quote Link to comment Share on other sites More sharing options...
SteveL Posted July 24, 2009 Share Posted July 24, 2009 You'll need to give the guys on here some proper readings in terms of actual temperatures. Can you post pictures of the gauges - that may help? Quote Link to comment Share on other sites More sharing options...

Lee P Posted July 24, 2009 Share Posted July 24, 2009 Its normaly deg c on the hks gauges, so 80-90 is normal for oil and water. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted July 25, 2009 Share Posted July 25, 2009 to tell you the true i have no clue, is about 3/4 of the way up on the gage! Its normaly deg c on the hks gauges, so 80-90 is normal for oil and water. This is exactly what I was going to say. If you dont have any idea what the gauges are reading how do you know its too hot:blink: Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 25, 2009 Share Posted July 25, 2009 Don't let the stock temp gauge fool you, it's designed to stay rock steady during all driving conditions to give an air of reliability. The water temps will however be fluctuating 20degC or more while all this is going on. Same for oil temps, and they can cheerfully go to 110degC all day. -Ian Quote Link to comment Share on other sites More sharing options...
Sharpie Posted July 25, 2009 Share Posted July 25, 2009 Whats +++++ might help us understand temp issues. BPU +++ has been used in the past where a + (plus) has indicated that you have moved up a level from basic BPU. It used to go something like: Stock BPU BPU+ BPU++ BPU+++ (also known as BPU and all the pluses) and OR APU Shown here: http://www.mkiv.com/techarticles/index.html More info here too: http://www.mkiv.com/faq/faqtt.html It's not used much here in Europe and not sure if they still use it across the pond these days either ?

Guest JDMDOM Posted July 28, 2009 Share Posted July 28, 2009 when i drive it hard i can actually see it going up. but most of the time i just cruzz and is very hard to get on the autobahn and only do 120-140km!! Quote Link to comment Share on other sites More sharing options...
Guest JDMDOM Posted July 28, 2009 Share Posted July 28, 2009 actually i had a compression check done last week and the block is rock steady so is the head gasket! the reason why i know the temp is not right is because it didn't used to be like that before. the car actually overheaded once and then i replace all the cooling componets, that's why i know is not running normal. i have the old 60mm hks oil and water temp along with thet oil press gages i got them from JP along with 90% of my parts the rest i got them from US. and yes is very strange!! i had all my friends over for a hole weekend trying to find out what the problems is so i decide to write the exprets who else that i really supra owner!

Guest JDMDOM Posted July 28, 2009 Share Posted July 28, 2009 is not a BHG i had a compression check done las week, block rock steady and the gasket is fine! also the belt and water pump is working correctly! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 28, 2009 Share Posted July 28, 2009 Get a proper mechanical temp gauge on it that gives proper read out figures in degrees C or F. If you have a front mount intercooler it may well be making the radiator, which also does a LOT of the oil cooling, so inefficient as to be inadequate on an autobahn in the summer.

SUPRASUZUKI Posted July 28, 2009 Share Posted July 28, 2009 Perhaps we should send this info to Bletchley Park? Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted July 28, 2009 Share Posted July 28, 2009 Is it possible that you weren't reaching the right temperatures before you changed the thermostat, and now you have a nice new one in there, it's functioning properly. As has been said several times in this thread, we need to know specific temp figures to know for sure. Quote Link to comment Share on other sites More sharing options...
Guest JDMDOM Posted July 29, 2009 Share Posted July 29, 2009 yeah i have to get to that! also i was thinking that the new electric fans that switch to does not have a shread so the air pulled by the fan might not go direc to the motor instead to the sides! or how about the timing on the cams can that be the problem?

Chris Wilson Posted July 29, 2009 Share Posted July 29, 2009 IMO electric fans are a downgrade in 90% of Supras, the engine fan shifts FAR more air, is properly ducted, and is driven by a thermostatically controlled viscous clutch. Why mess with it? If needed, on full drive by the clutch, it shifts a HUGE amount of air. It may draw a few BHP (say 2 or 3 BHP, maybe 4 ?) from the engine, but it has serious grunt when required. A 3 HP electric motor at 12 volts? Forget it, you'd have something huge, heavy with MASSIVE current draw. Quote Link to comment Share on other sites More sharing options...
