Hi peeps new to the forum, just swapped the engine in my car , its a 1.2 8v on a P plate, ive bled the coolant from the temp sensor but can hear bubbles on start up in the heater matrix/ am i bleeding it the right place or is there a way of bleeding it fom somwhere else

when changine the coolant in the haynes it does say bleed from the sender and leave car running for a few minutes with the expansion rad cap off (where you poured the coolant down- that lid off)

try re doing it again like i said above- it may make a difference.

its always worked for me this way cant say i hear bubbles in the matrix at all.

thanks gav ive done it twice but didnt run it for long but did have the expansion cap off do you have to keep sender open in the bleed position whilst running the engine

I would leave the cap on to get the system to pressurise and get hot then when fan kicks in slowly and steadily open the reservoir cap too depressurize then top up as the level drops.

(BE VERY CARFULL WHEN UNDOING LID AS WATER AS YOU KNOW CAN SCALD)

cheers tank top only problem with that is i havnt heard the fan kick in , so i will try that when the engine heats up

 

[tanktop]

Have you left reservoir cap off and squeezed the larger hoses coming off the radiator too?

If fan hasn't kicked in keep a close eye on temperature gauge.

yes i did that as a primary bleed before i started the engine ,,,, a very close eye is being kept on the temp gauge

 

[gav93]

on most corsa b's i have had the temp gauge doesnt budge till after 5-10 minutes idling so thats normal, have you never ever heard the fan cut in on your corsa? or just after you done the coolant change?

maybe a duff fan switch ? fans usually kick in around the 97-100 mark on the temp gauge though

ive only owned the car for about 2 and half weeks the first engine had a blown head and was getting hot never herd the fan tho. ill run it tommorow and let the temp come up to the 100 mark and see what happens, i no how to test the fan but is there any way of testing the sender
