Hi Guys

Sorry if this has been covered before but I couldn’t find it.
I was driving my L322 and temp needle started to rise 3/4 way up and I switched it off. I called the AA and the guy did a pressure test and said Headgasket is ok and water pump seems to be working but no circulation of water to engine. Water is 88 degrees but behind engine it’s approx 22 degrees. Radiator is cold also. AA said possible blockage somewhere. He had it running for 30mins with no overheating at all.
Also when u put heating on it’s all cold except one centre vent which is slightly warm.

Drives fine but after 30 mins needle starts to go up again. It’s not loosing any coolant as far as I can see.

Any ideas. Also any reasonable priced specialists in Dudley West Midlands are.

Thanks once again

Ifty
