Anyone know the correct bolts for the tstat cover? I have a waterpump but don't have the bolts to match up to new ones.

 

Ac delco 1575247 Water Pump Repair it's the bolt.
I can go measure the bolts i have and you can just go buy them at the hardware store.

 

If your able to get me the thread and size that would be awesome. In my fight to change my radiator, add efans, and redo some wiring the tstat bolts are missing.
Also discovered someone used the one piece tstat, cut the tstat out and silicone it to my waterpump. My water pump is supposed to have the 2 piece tstat and housing.

 

If i remember correctly the bolts are 6x1.0, as far as two piece tstat what year is your truck.. 04 up uses the two piece prior to that was one piece, hole in water oump is the same!!!

 

6mmx1.5
Roughly 1.25-1.5" long

 

The lq4 is out of a 2000. Tried the single piece tstat and it's too big, the housing hits on the sides. The seperate tstat and housing fits fine. Managed to find one today at autozone. Fit right in the pump no problems. My only thought is someone replaced the water pump. No history on the engine so I don't know.
Thank you for the bolt size.

 

Justmeasured a bolt its 6x1.0/24.16mm

 

Cool. Thanks. Gonna grab new bolts now
