MarcusEJ Posted August 27, 2013 Share Posted August 27, 2013 Going on a parts run for the supra on my lunch. I also need some coolant as heading back home after the meet yesterday was greeted by steam and bubbling coolant as it was low. Any advice of which one I need to buy? Thanx Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 27, 2013 Share Posted August 27, 2013 (edited) You possibly have a fault if your coolant is low, the rad cap is the first thing to replace unless you know its been done. use an O/E cap from Toyota. Heater matrix feed hoses are common to fail on these but can be easily replaced with either o/e hoses (expensive) or good quality silicon hoses for which there are lots of suppliers if you google it. http://www.merlinmotorsport.co.uk sell it and sell Samco which is one of the best A pre mixed Ethylene Glycol antifreeze is whats recommended, the system holds just under 10 litres if your thinking of changing it which again is what i'd do if you dont know how old it is or what it is Toyota sell CoolRed pre mix and discounted its approx £20 for 5 litres, do not use the Pink stuff they sell !! If you use a non pre mix don't mix it with tap water, just look at what it can do inside your kettle, you'll need distilled water if you go this route.

Dnk Posted August 27, 2013 Share Posted August 27, 2013 (edited) Is you rad the original ? some aftermarket rads use different caps so it would pay to check this before you buy a new cap. You can also have a simple pressure test done on the cooling system which should show if there are any leaks and shouldn't cost more than an hours labour, any proficient garage should be able to do that. Here is the cooling system pdf, page C0-18 shows the pressure test If you do decide to change the coolant it might be a good idea to also replace the thermostat unless you know its been done, again i'd use an o/e one from Toyota, (82 degrees C opening temp) i think the seal comes separate with these which you'll also need to replaceCO.pdf Edited August 27, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Big Mark Posted March 12, 2014 Share Posted March 12, 2014 Toyota sell CoolRed pre mix and discounted its approx £20 for 5 litres, do not use the Pink stuff they sell !! Why shouldn't the pink stuff be used? I've got 2 bottles of it at home and was going to use it to do my coolant change. Quote Link to comment Share on other sites More sharing options...
