car is 90 gxl

aight so after finding out that i was losing coolant (even though my temp gauge shows its was good) i went looking for the leak and the only place i think could be the problem was the thermostat. i suspected this becasue when i replaced it last week the gasket did not fit center. also i dont have a torque wrench so i just tighten it by hand and then some.

so i tried to tighten it some more and BAM the bolt snapped. FUUUUCCCC!!! took all day to drill it out now i just want to get this right before i go through this again.

the new gasket i used last week somewhat got smashed. so i want to get a new gasket. can i use the gasket sold at kregan? they dont hold the gasket needed by part number but they have something similar. its called FEL-PRO 35404 NEA 805 "water outlet gasket" or do i have to get a special one?

what size is this bolt? i brought it in and checked it with a nut and found a similar bolt size. metric class 8.8 M6-1.0x20mm is that correct?

how tight is 6.9-9.8 NM (70-100 cm-kg, 61-87 in-ib)? its just hand tight and then a little more right?

i kind of need help now because i need the car tommorrow. thank

 

well the bolt fits for now untill i find an oem replacement. i just want to know if the gasket will work. they look identical, and fit exactly the same. im just worried if theres a specail material it needs to be made out of.

if anyone could answer this id be very greatful so i can tighten it and drive down to kregan to get it torque, thanks.

 

haha this sounds exactly like what happened to me last sunday. the gasket didnt fit and the bolt broke after it. me and a fried just layered on the rtv sealant and... i think it worked! haha ran the car and no leaks

 

for a s5??? is a round oil seal type gasket... how did you replace the bolt?? size??

 

You don't need an "OEM replacement" bolt- there is nothing special about it.
If you coat it (and it's partners) with antiseize, future removal should be a breeze.
