cold engine

[kevin2]

I have a ford new holland 160hp wich has stopped going up to its working temp it has only 500 hrs on the clock so seems strange, have changed the thermostats and the sender and switch, changed the gauge as well, still the same, can anyone suggest anything else.

Does it <u>feel</u> hot to touch ?

What sort of indicated temp are you getting ?

Have you changed any cooling valve positions ?

Is it indirect or direct cooling ?

Has the ambient temperature changed dramatically since it was running hot ?

 

[RIN]

get one of these from Maplin and check the temperature at various points on the engine and cooling system. This might pinpoint the problem

 

[kevin2]

No not hot to the touch - this is a twin engine installation and the Stb'd engine is hotter to the touch. It's the Port engine that's cool.
Temperature is usually 85 degrees C (now 70)
No change to cooling valve positions
Cooling through heat exchanger
No to dramatic temp change.

Thanks for your help - keep it coming!!!!

Thanks for that, This is the cheapest I've seen.

Thanks for your interest

Is it also heating your domestic water onboard.

Just a thought and a very long shot but has the heat exchanger got a problem if raw water is by passing the matrix somehow it could be keeping the temps down

 

[kevin2]

Ok thanks for that, have orderd a laser thermomter from maplin will check around the block. Will also drain exchanger start engine and see if salt water comes in from matrix. Could it be a problem with the engine fresh watre pump?

Hi yes it heats the calorifier 40lt tank.

Turn off the flow to the colorifier and see if the engine reaches temperature.

I would have thought that you would loose water if the heatexchanger was faulty!

Hi, Will try turning off the flow,(Do you know why this would make a difference) Am not losing any water, thanks again for your response.

The engine is heating the 40ltrs of very cold water.

No need to drain down to see if sea water is getting in the header tank just taste it, sea=salt antifreeze=sweet. Probably down the hot water system, and the ambient temprature outside.
