(1981 non-turbo 242) Just checking before I order some parts. The three sensors/switches lined up on the head under the intake manifold are, from front to back: coolant temp switch, engine temp sensor, thermo time switch for cold start injector?? Do I have this right?? Thanks for all the feedback on this job. I decided to replace a bunch of stuff under the manifold while I'm there. I'm having fun checking out the FCPGroton site for parts. I hear they are reputable. Can anyone recommend other reputable sites?? We have two 240's and I'm enjoying learning to fix 'em. I need to know the good places to buy parts. One last thing, are the Elring intake manifold gaskets the same quality as the Volvo ones?
