Hi, i need to remove the intake manifold to install a block heater. Is it possible to reuse the gasket, that i dont need to remove the exhaust manifold, could i use som rtv (high temperature) or will the gasket break when remvoing the intake manifold anyway? Is it difficult to remove the exhaust manifold to replace the gasket? Its a GC 1993 4.0L

 

Dont reuse it, how would you like to do the job twice to save 20 bucks??

 

If you remove the front drive shaft won't that allow you enough room to do this from underneath?

 

Maybe, but i have started to remove the intake manifold. I got a new gasket :-)

 

wow dude have you never heard of an external block heater

Is that realy any good? Maybe for battery and oil, but for the water? I havent seen anything like that in Norway in shops where they sell warmers for cars. Block heater is the one to go?, but mybe i should use one of that on the oil and transmission since the car is going to be used very very litle.

 

standard 50 50 mix is good down to - 37f (from what ive read when temps are in minus range there close to the same celcius and fahrenheit) so i would assume a little stronger mix would prevent freezeing. from what i read temps there go down to minus 40c.

I ve always thought block heaters were for the oil anyways and it stands to reason if the block is warm than any coolant in the block is going to be way above freezeing also.Am i missing something ?
