Where do you connect yhe hot start engine hester at

Dear Customer This specific model of heater connects to a regular 120V outlet like the one you find inside your home. Other models can offer different connection options depending on the customer needs. If you have any further questions please let me know. Thunder Parts Team

Would this be usable in a Jeep Grand Cherokee?

You could use this in an automotive application as a winter block heater, but the size is more conducive to a gen-set or other stationary power applications. There are compact, in-line block heaters available that are more suitable to a vehicle.

How is this able to circulate the engine coolant if it doesn't get hot enough to open the thermostat in the engine?

These heaters are primarily used for off-road engines on generator sets, etc. The idea is to heat the engine block, not the radiator, which would waste valuable energy. If the engine thermostat opens, too much heated coolant goes into the radiator. The hoses should be connected at 2 points on the engine block. These work on the thermosiphon principle. The "hot hose" leaving the heater goes to a higher point on the block, and the return hose from a lower point on the engine drains into the bottom of the heater causing coolant to circulate. Be sure to bleed the air out of the heater and hoses prior to plugging it in! Tech Support @ ASAP

What is the diameter of the hose connections?

All of the Hotstart TPS series heaters of this "body style" have the 5/8" hose nipples. Best wishes, Dennis @ ASAP
