QuoteHi can you help please, the rad on my wolseley nine gets very hot when I switch off the engine, now it doesn’t boil, this is after running for about 15 minutes, I put an electric fan on the rad and I’m thinking of fitting a davies craig circulation pump also do you think that this would help with the cooling, thank you,

I’m afraid I don’t have any suggestions for your query, but if no one else can put forward any ideas, I would suggest that you contact the Register’s technical adviser for these cars, Dave Palmer. His details can be found on the website and in Wolseley World.

OfflinePeter the first thing to say is that when the engine of any vehicle is stopped the heat rises and the radiator gets hotter. You say that it doesn’t boil but 15 minutes is not long for an engine to get up to normal working temperature. What happens after a good long run? I assume that as the Wasp engine is a Four cylinder version of the Hornet unit it will have a waterpump anyway so I’m not sure if fitting an auxilliary one would be of any benefit. Electric cooling fans are a good idea if like the Hornet Special the Wasp doesn’t have fan blades. It’s important that the ignition timing is set correctly and that it’s not running retarded. I used to set my Hornet Special at TDC withe the A/R lever in the retard position. My Series111 Wolseleys both suffer with fuel vaporisation when the heat rises after the engine is stopped after a fast run. To start them then requires the use of the choke but once running neither overheats.
To sum up if it doesn’t boil when being driven it’s perfectly ok.
As Bob suggested it would be worth a call to the technical adviser for any further help.

OfflineMy suggestion would be a thorough engine and radiator flush, until it runs clear, and as stated by Graham if it isn’t boiling I would say it’s ok.
Could also be a blockage around the waterways from rust/ corrosion build up, David.
If it looks right, it probably is right.

OfflineThank you all for your reply, that’s what I’m afraid of that the galleries may be corroded, when the engine was restored we cleaned as much as we could get at, it was bad OK but I haven’t driven it yet so I’m worried of the consequences, fingers crossed.

OfflineRun it carefully over short distances and gradually increase the speed and mileage untill you are confident that all is well. Without seeing how the car performs on the road it’s hard to be more specific. When you are driving it if you aren’t happy then stop and check it out.

OfflineI would flush it out again after each run, and reverse flush if you can.
You may dislodge any rust, again flush until clear again, good luck.
If it looks right, it probably is right.

OfflineThank you David,
The radiator has been rebuilt so should be OK??

OfflineI was thinking of the waterways in the cylinder head and block, rather than the radiator, reverse flushing would help to clear any rust debris.
If it looks right, it probably is right.

OfflineIf you are concerned that there is still debris in the block….
Sorry to say this…. But you don’t want to run it through your nice new clean radiator……

OfflineThe problem with all the small, (Nine/ Wasp & Hornets), Wolseley overhead cam engines is that the cooling water is directed to the rear water jacket plate. This tends to leave the front cylinders hot. The last engines as in the 14hp special took the cool water to the front water jacket.
I have moved the water inlet to the front on all my Nines & Wasps. I also fitted a Craig-Davies water pump, (Nines & Wasps never had a water pump), However it never switched on, hence I removed it.
West Yorkshire this summer, I used a Wasp daily. It never over heated.
I would check that the water galleries are free of rust. I often find I have to break it up by hammering a screwdriver through the water galleries in the block.

OfflineThank you, just back on the site after a short while hence the delay in thanking you for your advice, can you please send me some photos of where you mounted the davies craig pump on the nine,
Regards Peter Fleming.
