| How do you check if the thermostat is working OK? (1/00) |

If the engine warms up quickly (within 2 miles?) to just below half way up the temp gauge, and then stays there (almost regardless of operating conditions) it's OK - if not - it's not. If it fails open, the engine will hardly warm up (by the gauge), or take a long long time to do so. If it fails closed - you'll boil, or at least the temp gauge will be well up in the top half all the time. (Both these assume the coolant level is OK). They can fail either way. (1/00) |
| I am planning to change the thermostat on my 1990 Eunos Roadster this weekend and I am after some advice. Does anybody know if a thermostat for a UK car will fit a Eunos? I presume it will, but would like to be sure. In the past I fitted one to a Mk 1 Golf but had a problem when the studs holding the thermostat cover on sheared. Has anyone got any advice on how to avoid this on a Roadster, or if it will be a problem at all? I would appreciate any advice or tips you all may have. (1/00) |
| should be the same as UK car .. certainly never bother to change them over when fitting a UK engine to a Eunos! .. just be careful .. the housing is on a 3" long fragile stalk which was broken on my second engine.. oh so I have fitted a Eunos thermostat to a UK car!! (but in a Eunos housing!!). Careful application of science is required .. not brutal application of force... (1/00) |
| I have fitted a 'UK' thermostat to my Roadster - no problems at all - why should there be? Fit a new gasket (comes with the thermostat) and install it the right way round - printed face towards the thermostat. It is vital to make absolutely sure that the thermostat cover is properly located and is pressed right down to the gasket and is not 'cocked up' on the thermostat itself before inserting and tightening the bolts - which should be finally tightened with a torque wrench to 14-19 ft lbs (So no gorillas needed here!) The danger is not really of shearing / stripping the bolts - although you can do that if you tighten them too much - but of cracking the thermostat cover if it's not on straight. If you haven't got a torque wrench, I'd advise anyone to get one - most people who haven't way overtighten nuts and bolts. (1/00) |
| Yes, no problem. Fits fine. You get 3 gastkets with the thermo, but it's pretty obvious which one fits (1/00) |
