13/60 getting hot

[s.leah]

I took my 13/60 on the longest run since I've had it today. 200 mile round trip.

I noticed going along dual carridgeways at around 3k~3.5k rpm that after 5 or 6 miles the temperature would get fairly high, still in the white though.

Normally tootling around town it never goes above half way, and in the cold winter it can barely get a quarter way doing local runs.

 

I'm assuming this is probably perfectly normal on long runs at modest to high rpm? There's nothing to make me think anything is wrong apart from the fairly high temp. reading

When I backed off and cruised under 3k rpm it did start to cool again. Not that easy on a dual carridgeway or m-way with the big trucks thundering past! LOL

 

Is it worth fitting an electric fan for road trips, especially when the weather is hot, as I can see it getting too close to red for comfort?

An overdrive gearbox is your friend. They can run a bit hot over 65 as its high revs, the oil thins too so if using motorways an oil cooler could be considered. TBH as long as its not running too hot I wouldnt stress.

You could be having voltage stabiliser failings here, if running a dynamo the low speed voltage will be less than high speed to some degree and this will give you the change in readings that seem speed related

Electric fan wont help at speed the ram effect is more than adequate

Other ideas are the thermostat should controll the temperature , if its not warming on cool, days then its time to change it., stick to an 82c stat.

 

If you get into deeper problems then blocked tubes in the radiator or a pending head gasket is

over the horizon

First thing I'd do is a thorough flush of the radiator AND engine block. It's cheap, doesn't take long, and chances are it was due to be done regardless.

Thanks for the thoughts. I happy there's no electrical issue as I'm all alternator'd up

 

Interesting point about a 'leccy fan not being effective at speed, I hadn't thought of it like that!

 

I might give it a flush as suggested.

You need To detemine if this is a cooling problem or a reading problem

 

Cooling , get a cheap thermometer from the chemist, run her to get a high reading with the cap on loose

on its first click, then you wont pressurise, pull over in a layby remove cap and stick thermometer in the rad filler see what youmget, easier if you geta cheap infra red you can point it at and get a reading .

 

 

if you have a volt meter /multimeter take a link off between the gauge voltage stabiler and earth

if its smiths unit you should get a pulsed 10.5volts all the time you are running

anything above this will give you high reading

 

If the thermometer reads around 82c

Sorry cant get a page on this silly tablet,

if the engine temp turns out ok then its a reading problem with stabiliser, sender or gauge

 

check the easy before you start spending .or getting messy

I found that the fuel gauge was also reading high when I thought the car was overheating all down to a knackered stabilizer.
