Water Temp upto 120 degrees then back to 90??

Ok, just had to drive home from work at 20mph. If I go over 2000rpm the temp starts to rise so I've had to do the whole going down hills with the clutch in scenario. So it looks like the water pump.

Just picked the car up from JBS. Had the cylinder head pressure and crack tested, no problems there (phew). Had the cambelt and water pump changed because they were due anyway but the problem turned out to be the thermostat.

So, problem solved and thanks for everyone's input.

As i said it's not unusual for them to stick closed but rarer than them sticking open.

It's the first one Kev has seen. He got the car to warm up to above 90 degrees and the bottom pipe was still cold.

A lot of failing thermostats lately i must say

Omg the thermostat I was right! lol. But does the CTS read over 90s or not ? I would like to know for sure, i guess it doesn't since you said your CTS/CC was 90' whilst your needle was 110 ;/

I had second thoughts after some the other reply's but I had this happen to me on my old Renault 5 stuck shut so I just took it out..

Glad you got it sorted m8...

I'd say 90 was the max reading, nice one for pointing out the cc functions though.
