I cleaned out my raditor front,and replaced all hoses,thermostat ect: Put new therm. gasket and torqued down,but inlet leakes. when i removed old gasket there was no sealer on it. Should i use some now?
Most likely the T-stat hsg. is warped or cracked. Easy fix is to purchase a new O-ring designed T-stat housing and install. Be careful when you tighten the bolts as you can warp or crack these also. I always put a flat washer under the head of the bolt even though it not suppose to require them. Tighten down to snug and 1/4 turn of the bolt and you are good to go. No sealer required with o-ring type t-stat hsg. and it is reusable.
Can you let me know where to get a new water inlet ,for 84 vette. I tried a new gasket and peratex , although it did improve the antifreeze leaking, it still leaks a little. I may have a warped houseing. I found out GM has disco. it
