Where is the map sensor 1993 Chevrolet van g20

SOURCE: 1993 chevy van g20 water pump replacement

you will need some fairly long wrenchs 15mm-16mm to get leverage on the spring loaded serp tesiner put a wrench on the pulley near the belt ? also loosen the 4 fan bolts on the water pump before you remove the belt ? ther are 7 fan shroud bolts you can split the fan shroud ? 2 bolts on the lower right and 2 on the left ? after you do this then you should be down to pulling off the fan and pulley just slides off ? then remove the 4 waterpump mounting boltss, scrape the old gaskets ? when this is done all you have left is to installthe fan studs from the old pump? you do this by screwing down 2 nuts on the stud then with 2 wrenchs lock the nuts together ? then unscrew the bottom nut ? keep doing that till all 4 are replaced? install the gaskets and add some silicone and reverse the process ? hope this helps repost thumbs up !!
