Re: [doc] More Cooling Problems

Thanks, I hadn't considered the impeller. The car done <12,000 miles, 
with fewer than 400miles in the last 12 years! I purchased it two 
months, and ~80miles ago. The thermostat is brand new and all the 
easily visible hoses appear OK. The first trip I took was ~20miles 
birnging it home on an empty motorway. I have been careful not to 
exceed ~60mph to run the engine in again, but even in this trip with 
constant airflow due to the motion the gauge got very high. The test 
dirves before purchase were relatively short, and the previous owner 
didn't take it on long trips so the problem may have been hiding for 
some time.

I have wired a bypass switch so that I can run the cooling fans 
constantly but this does not improve the situation whilst in motion.

Another thing to consider, however rare, is that the water pump 
impeller could have come loose and is spinning on the shaft. Also 
check that the coolant hoses/pipes aren't crushed or kinked.

Did the car aquire this problem suddenly? A radiator isn't going to 
clog overnight.
