Really wound up now ! Came to do my thermostat today so I popped the engine cover off then went to remove the little cover (over the dipstick) this is where the fun started...the screws look like the same kind that are used to hold the main cover on...but I cannot budge them...so that puts an end to my stat replacement until I can ! What type of screws are they ? Philips, crosshead ? just the normal twist and remove ones ? Was about to just yank the whole thing off when I decided to come in for a breather !
