Had my car now for 3 weeks wrx bug eye drove it every day for 3 weeks and has been 100%
in the paper work the heads were done 600 miles ago new rad etc... but today i have been driving it and heaters are nice and warm and the temp gauge is one notch above cold next minute the heaters go cold and temp rises above half way and so on... as i parked up with the heaters blowing cold if i rev over 5000rpm heaters blow hot then if i let off the gas blow cold could tjis be the thermo as i called the garage who did the head and he said the water pump was in very good nick??
oh and if it is the thermo few people have told me to take it out as there nothing but trouble! and where is the thermostat on the wrx bug eye cheers
