give the engine a compression test,maybe the gasket is bye bye

[mk2escortmad]

i really hope the hg hasnt gone

[Josh_gsy]

you sure there isnt a blockage or the new thermostat works?

test it by putting it in boiling water and see if it opens?!

[Jay_harrier]

Have you flushed the radiator too? try reverse flushing the system as well.

 

If the top rad hose gets hot then your thermostat is probably ok

there could also be a vapor block, fill it up with water and run it for a few mins and it sholud force out any water in the system

[Guest cortinamad-gonetoo]

as all above really flush reverse flush check head (compresion test) thermostat water pump

 

it wont matter that your not running a heater matrix i ran one without a heater for ages and it was fine

[mk2escortmad]

cheeRS for the advice guys, could i jst run it without a thermostat?

i run my mk2 with out a stat for a month untill i had the head gasket done.

is it throwing water out the overflow? also is the whole rad getting hot? has the water gone rusty a second time?

[mk2escortmad]

the water was rusty but i havent checket it again yet

[bomber1]

mine was rusty run it for 4months b4 i got new hoses etc. it would get hot but not to bad. then i used some of my mates central heating cleaner acid stuff. must of cleaned the rust out of the head gasket where it was blown cos after that it was blowing water out the overflow and getting hot in ten or so minutes the gasket had blowen between no3 cylinder and the water route

[oliwally]

is it boiling up or the guage getting hot? could just be a duff sender?

I don't expect you really need them in Malta. Over here however it's a little colder in Winter and without a thermostat your engine wouldn't get up to proper operating temperature.

That the inside of your engines rusty,not had any A/F for a long time.

All those lil bits of corrosion floating around your cooling system.

As everyone has said,spend the afternoon flushing your engine back and forth,though all hoses,etc till you get clean water.

take ONE hose off and block the waters escape and get some pressure built up and the let it go.

Should see some nasty colours come out of the rad/engine

 

Also drill 2 2mm holes in the thermostat to help get rid of any air locks that could get trapped behind it.

 

Also what grade oil you using? when i ran my 2L capri on 10/30 temp gauge was always on or near the red,switched to 20/50 and it never went past 3/4

cheeRS for the advice guys, i done wat joker said and it seems to be running fine now by not overheating quick, as to it maybe a dodgey sender i could be that too but the water seems to disappear but the rad cap not hot

very weird car

[oliwally]

are you filling the water to the neck of the cap? thats too much water

you need at least 1/2" below the neck
