    Thermostat bolts?

    Does anyone know what size bolts go on the thermostat? Just snapped both of them trying to get them to factory specs... Heading back out to have some fun with a drill now.

    Probably the easiest way is going to be calling a local dealer. Most will spare some time and tell you the bolt spec's.

    I searched real quick and couldn't find it.

    To save yourself a lot of headache, it's best to remove the water pump all together so you'll have an easier time drilling out/retapping the hole.

    Good luck

    That's exactly what I did, replaced it as well while I had it out. The bolts ended up being 6.10 and about an inch and a half long.
