Hi, I have a MG ZR 1.4 2002 with a K series engine as always. I recently had a leak behind the inlet manfold, I changed that with a new gasket and while I was at it I changed the Thermostat too Now My car's cooling is Totally messed up.
after all the hard work I noticed the Fan stopped kicking, when and how it used too (normally when temps hit 88 degrees). I bought expansive coolant
that I took perstion mixing in order to get the Right mix... Now the crazy bit is, I have been Trying to bled this system Like No Mans business. I was trying to Back flash the cooling so I got a garden Horse and put it to at the bottom rad pipe but No water cam out from the top pipe (engine side) this was me learning how the C.system works so think it could not get round the therm as it worked the other way round. so I put things back and tried bleding it again and again using the bled value that is in between the Airfilter and block with No positive out come.
- NOw Heaters are blowing Cold even tho i was bleding while on High (max), they do get JUST warm NOT hot and to get them warm it takes what seems to be years (30min).
- The temp gauge also takes longer too to get up to normal temp
Can anyone Please please Help me on how to bled a system, if I need to have the engine on? which pipe first? what not to do? how to cheak all I well? Ohh as for the fan, It still does not kick in and i have even got a new sensor placed, relays and all fuses changed (when Unplugged it does spinn so Fan is in working order just not with temp)
