Hot under the bonnet

I thought after a busy work day, I'd take a mini retail therapy trip to the Trafford Centre.
I need to new pair of jeans after chucking out my scruffy old faithfuls & Ferguson is in desperate need for some new pyjamas.
After collecting my car from the garage this morning, having a new water pump fitted & handing over the princely sum of £200, I had no doubt in my mind I'd experience any more overheat issues.
After purchasing said jeans, pjs & a Christmas jumper (!), I headed home.
Before i even reached the motorway, the needle was racing towards "H" & I felt pretty uneasy about the journey ahead!
Given the late hour & being by myself, I was really worried about breaking down, and had visions of my car just bursting into flames at any minute...
Thankfully, by the grace of god (& skipping the petrol purchase) I got back okay.
I really need to get back to the garage tomorrow & try & get it sorted out....I have a feeling the problem he originally thought still remains-the head gasket.
That's a pretty expensive job, I believe...
