Thread: 4.4 getting warm.

Get use to it. 4.4's just run hot. Chased it your years. The only way I ended up getting it to run cooler was to get rid of the air-con and remove the condenser in front of the radiator.

Hi,

Make sure the earth for the gauge is good. Very common in older cars that a bad earth gives wrong signal i.e. running too warm.

Run a separate earth or fiddle with the earth wire while running and see if there is any difference. That would be my bet.

If that doesn't work get a new temp sender and see if that makes any
difference.

good luck, DL

Get a real temp gauge the capiliary type is the best also the trick with a 4.4 in a rangie is a oil cooler and a good oil pump and either a electric thermo fan or a big clutch type fan and use a cowling if its running the poxy metal one ditch it for sumthing beta

When building mine I noticed the water jacket ports in the head face were restricted (compared to the rover). I opened them up to match the block and cleaned out some dags in inside the head jacket. I havn't had any hot issues since. Including hot day beach work.

It had a thermostat with no guts only when I got it, removing that didn't do much other than run a little cold last night over the Blacks Spur, today I fitted a new 190 deg thermostat and all that seems to do is allow the motor to get warm quicker but not any hotter.

Obviously I don't want to cook it.

Any ideas.

I'd put in a 160 degree thermostat, especially spring/summer time coming up.

160 would be a bit cool. 190 is closer to the cool end of what you would want. Would not go any lower than 180.

Euan, exactly which water jackets did you open up?

4.4's run hot even in the P76 and the trucks they were used in.....

Fix....
big radiators and look after it...

The sloted ports at the back matching to the block, and the ports at the front mateing to the inlet manifold (coolant tract).
