I am in the process of doing the final assembly for my new set of timing gears, and it has become very cold in the last few days, and I don't have a garage. My question is with the various sealants I need to use to dress the gaskets, seal the oil seals, water pump, etc, will the cure in weather hovering around freezing? I looked through all of Permatex's spec sheets, and they give an operating range of various temps, all the way to -65 degrees, but thats not for proper curing is it? If anyone has any suggestions let me know. I want to get this thing back together before the weather gets even worse.

 

I have used copper coat put it on the part & light it blow it out then apply gasket Not recommended to put on the engine & light !!! If every thing is clean it will cure quickly Make sure you shake the can , I usually put a old nut in it for agitation It must be copper colored not green

 

The curing process will slow considerably, and usually involves heat in the process. As I understand you can use sealants in the cold, you will just have to wait longer for them to set up. paints on the other hand...

 

You should be fine. Just make sure all of the surfaces are clean. Make sure you torque the timing chain cover properly and give it plenty of time to set up.

 

unless you used rtv-you only need to let it dry a little longer-it's solvent evaporation that is the concern here, curing is for rtv(room temperature vulcanizing) sealants, which may actually freeze below 32f.
