hi
all
ive got a problem with my heater matrix it keeps breaking when i give my car welly from start,i think it might be over pressure possibly due to the rad caps i got on there they where on the car when bought car they are **** 1.1kg/cm2 which is 108kpa or 1.08 bar if i drive car sensibly and dont really race it is fine havent had any probs with over heating and the guage is normal,read a post where you should only have one pressure cap is this true on thermostat housing and not the tank
thanks in advance
