Welcome Visitor! Please take a few seconds and I have a 2001 Ranger XLT 3.0L gas and for the hundredth time it feels like my thermostat housing is leaking. Does anyone happen to know the bolt size of the bolts that secure the thermostat housing to the block because mine look like crap and I would like to replace them too. Ford Rangers just seem to enjoy leaking antifreeze. I almost think that the last people who worked on my truck put in the wrong bolts because it seems like no matter what, there is a gap like the bolts do not fit.
