MG ZT-T+ 120 (F/Lift - Manual) Coolant Temp. reaching 105°C

Time Searcher · 13th February 2015, 09:06

1. In ambient temperatures of +5° to +15°C, recently the coolant temperature has been reaching 105°C.
2. 'Hans' temp. gauge fitted.
3. 'Gerry T' fitted
4. Coolant level is below the Min. mark when cold, topped up with about 250ml then is sitting at 'MAX' (bottom of fins.)
5. Gold resistor fitted 18 months ago.
6. Fan Slow Speed checked using the suggested method.
7. Indicated temp. reaches 97°C in about 2 miles from start-up.
8. Long trips (c100 miles)- indicated temp. remains at about 97°C.
9. Indicated temp. rises to over 100°C on steeper hills, in 4th or 5th. gear, but returns to 'normal' on the flat.
10. I have checked all hose connections and around the thermostat housing for any signs of leaks, none found.

Vehicle is one of the last ones built and I have had it from new, just under 50,000 miles on the clock and has been the most reliable motor that I have had. (Coolant temperature has never been over 100°C that I have noticed)

I am planning to drive back to the U.K. in a few weeks - some 1500 miles each way, do you think that I might be heading for trouble with the above conditions?)
Cheers...
