high temp....and leak still.....

[telski789]

hi,firstly......since i replaced my rad my temp sits just over halfway,it used to just past the quarter,i dont like it this high! all the pipes get very hot and ive replaced the thermostat. the weird thing is that even at that high temp when i turn the engine off and feel the rad it feels cold all over,does the fan really keep it that cold??? ive opened the bleed screw loads with the heater on full and just water comes out,strange one!

also,i still have a leak,i had my windscreen re-fitted but im still getting a trickle in the corner behind the bonnet release,doing my f**kin headin!! the carpets been out for weeks! ive sealed the rubber grommet where the wires and headlight adjuster hoses come through,definetly not coming from there,only thing i can think of is if its coming through where the bonnet release hose comes through? ive had the dash completey ou but taht is still hidden behind the wiring and soundproofing,theres absolutely no rust as ive taken the fusebox off and looked under and its solid,im gonna fit a drip tank soon and be done with it!!! got that 3.5 to put in soon but i need to sort this first!! cheers for any help!!

that cooling problem sounds like a thermostat not working mate

[bigun]

is there a bleed screw in the top of the thermostat if so run her up and open the bleed screw to get all the air out its a 8mm

[telski789]

the thermostat is brand new and after it warms up the hose the other side of the stat gets very hot,so its definetly opening,i have bled it using the 8mm screw,strange! im running out of ideas too! the water pump is only 5000 miles old too! keep em coming!! cheers

sorry just read your post again and note you have replaced the thermostat. Also that you have beld it plenty.

Hmm, if it is chucking plenty of water out with the bleed screw open this suggests the water pump is doing as it should.

Was it a new rad or a second hand one?

[telski789]

second hand!!! looked like it had hardly been used though,no fan blade marks or even any signs that it ever had onein front of it!! unlike my old one!! i put a hose through it to check it was clear,am i bad?!!!

if all pipes are hot and the rad is cold i would still say theres air in it

[E30BeemerLad]

was just gonna check to see if you had poked a hose into it to check it was claar.

Well, i'm all out of suggestions too

[telski789]

i might try running it tomoro with the fan off the motor and see if the rad gets hot,only thing i can think of,if it does stay cold,what then?!!!

[E30BeemerLad]

tel, the rad should get hot, that's the whole point, they are not that efficient at cooling down.

as the other fella says, can only really be an air lock of sorts

not sure how you sort that, would you pull the bottom hose off and drain and start again???

[telski789]

yeah i know! but i thought maybe the fan was working overtime!! i'll see what happens tomoro,all i know is ive bled that mofo to death!!! theres another e30 come in at the scrappy with my rad,i might have that for a fiver and see what happens!! its the anti-freeze what kills my wallet!!

dont put the anti freeze in until you have got all the pipes and rad hot i did mine in the week after re building the engine on my sport just let it run low with the bleeder open then fill her up with the anti freeze in
