Dear Ramyflag, Your instructions to replace the heater core were very accurate! Mine is the 95 4 cyl.-I think the first year of the difficult-to-replace heater core. After realizing how pathetic the Haynes Manual instructions are for heater core replacement, I went to searching and found your thread. Took me just over 4 hrs to complete the job. Not really that difficult- with the right instructions! Many thanks for your careful input for this subject. Maybe you should start a repair manual co. and give haynes a run for their money!
