cooling problem 24 v.

arcturus · Aug 12th, 2006, 00:06

92: 3 ltr. 24 v. 960. Whilst out on a run I noticed that my temp guage came to it's normal position in town at normal town speeds (30 ish,) and when I drove on the by pass at cruising speed (60 ish) the reading dropped to cool. When I returned to slower speeds It returned to normal. I suspect the cooling fan staying on or a faulty 'stat. Any opinions would be appreciated.

PS. No,its not the fan, I was able to look at it this morning in daylight.

is the car taking longer time to reach it's normal running temperature if it is it sounds like the coolant thermostat is sticking open and over cooling the engine

As said above it is most likely to be the thermostat, they are very common failure with the straight 6's. They usually fail open so the only consequence is overcooling, but I have known them buckle and fail in the closed position.

Just a point to note, when my t'stat failed I went to the local motor factors to get one and asked for a 'stat for a 960. They asked me for the engine size to which I replied it doesn't matter as they are the same. Their computer system had different prices for the 2.5 and 3.0 versions, so I asked them to check the 850 and S40 versions as well because the whiteblock series of engine use the same stat. They came up with £3.29 for the S40 1.6, £3.59 for the S40 2.0, £3.89 for the 850 2.0, £4.29 for the 850 2.5 and 960 2.5, and £4.59 for the 960 3.0.
I got them to check the catalogue for the part no. to confirm it was the same part and then asked for a 'stat for a S40 1.6!

Thanks, I thought as much. Just one thing. I know that I need to drain some coolant out but I'm not sure where to drain from. I suppose it will be the block and the drain plug/tap will be in some strange inaccessible place. it won't be somewhere easy like the rad.

You're in luck, the rad has a drain plug on the lower driver's side corner. It will either need an Allen Key or a Large Flat Blade Screwdriver to undo it.
