Firstly be warned there may be a RANTING in this post . . . . . FECKING PRIOR OWNERS / DODGY GARAGE ! Even my daughter could and does do better !
Along with the list of initial planned maintenance is the cooling system.
As we are in the sand pit here this always has the potential to go wrong quickly and in a big way.
So routine changing of hoses is always a good plan.
After having a look under the bonnet the hoses look . . . . . Good to Iffy.
Also the temperature gauge never seems to move more than about 10C past the 'Cold' point on the gauage, never even close to 'Normal'.
So in from the UK comes :-
- Complete Silicone hose kit (much longer lasting and better flow than rubber)
- New temperature sensor (thermistor type)
- New 75C thermostat (75C is for summer / hard use)
First pull off the hoses.
WHAT THE FECK !
Cracked and bodged up with bath sealant !
Okay just drain the system and flush with hose then fit the hoses back.
Even a modification to tidy up the top hose to the heater box.
Next the temperature sensor.
Single wire sensor which is earthed through the engine.
Its a thermistor which means that the resistance drops as it heats up.
So if the sensor plug is insulated from the body it gives a false cold.
Such as by . . . . . . TEFLON TAPE, another WTF !!!!
I know the gauge works because I shorted the cable to the engine and needle quickly went to 'H'.
So clean the threads and fit the new sensor job done.
The seal comes from a conical face on the bottom, not by using teflon !
Lastly the thermostat.
Before fitting CHECK. While the wife isn't looking heat in a pan of water on the stove.
Opens about 75-80 which is fine.
Now remove the thermostat housing and remove thermostat.
Wait. . . . remove thermostat. . . . . . WTF NO THERMOSTAT !!!
Okay fairly straight forward, fit new thermostat, including new gasket.
The old elbow had a mounting bracket for a so called smog pump.
The smog pump isn’t fitted so to tidy up, out with the hacksaw and grinder.
Bolt it all back up and fill her up.
Fire her up and wave the laser thermometer around.
After few minutes all seemed to work, as temperature came up thermostat opened followed by radiator getting hot.
All Done, this is considered to be okay / normal.
As the engine was effectively over cooling, fingers crossed nothing to badly damaged.
Just hope nothing more sinister lurking and that she now doesn't start running hot.
If so I suspect will be new water pump which is a pain as means radiator off.
Next . . . . . Seats bases, unless Prince of Darkness Lord Lucas strikes or I end up doing the water pump !
