i was going to replace motor mounts for a 305 and i was woundering what the easyest way to do so and if i should just replace the broken one or all? Does ne1 know if an engine will run better with more expensive spark plugs or if it is just fine to use cheaper one's like bosch super (like $1 each)? Could some 1 help with a radiator problem. i tried to fill it today and i started the car and turned the heat on and then started filling radiator with fluid. when it seemed full after running for about 3mins it started to take the air bubbles out and then it seemed to start pouring out so it was impossable to put the cap back on without getting burned so i shut off the car and it shot right out like it was puking. Should i just fill the radiator and put the cap on with the car off? will it be fine that way?

i would replace both motor mounts, if one is already toast the other should follow shortly. for the rad question, were you just adding more fluid, or was the whole system drained and you were filling it up? there is probly an air pocket. did it over heat at all?

i had a hose break and i fixed it and i only put 1 jug of fluid in and then filled it with water. it didnt work out very well like it would boil and spill out if the over fill tank so i checked it and it was low so i added fluid to existing fluid in the radiator and a little water then thats when the problem happened.
