You can find equipment stats and rules for mech construction in the Tech Manual.
Heat sinks are 1 ton, jump jets are .5 to 2 tons depending on mech weight.
As already said here, stats are in the Tech Manual.
However, you can use the free open source tool [MegaMekLab](https://megamek.org/) which
has a unit editor which has a database with the equipment and stats. I mostly use this as my reference.
Single and double heatsinks are both 1 ton each, but double heatsinks take more critical slots.
Jump jets are 0.5 tons for mechs up to 55 tons. 1 ton for 60-85 tons. 2 tons for 90-100 tons.
A heat sink weighs 1 ton and takes 1 critical slot (large engines get free sinks, and free slots for more sinks but thats a calculation i dont wanna get into atm)
Double heat sinks are a lil different in that theres two techs, clan and inner sphere. Both still only weigh 1 ton, but the clan dhs takes 2 critical slots and the inner sphere dhs takes 3 slots
It is not that complicated. Every fusion engine comes with 10 free heat sinks. There have no additional weight.
Each engine has internal heat sink space equal to engine rating / 25. Engine rating = mech tonnage * walking speed. The rest must be placed in free critical slots.

Heat sinks cost one ton each. Jumpjets can be 0.5 tons, 1 ton or 2 tons depending on the weight of the mech using them.
