I have a heating problem onn 2006 chrysler 300 touring. with no engine light? temp guage just shoots up while running then comes back dwon to normal? how do i fix this?

Well most of the time your problem is due to the thermostat sticking and or stuffed so 1st replace it but fit it the correct way around (the spring like part to the bottom).
Then theres the Radiator bunged up with dust and dirt out side fins or not using coolant or antifreeze and using just plain water then the block is just getting full of rust which will cause the same problem(but if using coolant your ok) OR bad air flow through Rad, Fan could also be a problem ..so check it all out the above and let me know

I presume the engine is actually overheating -(not just a temperature gauge sender issue - check for poor connection at sender).

If so, go through the checklist following:-

1) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
2) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
3) Check coolant reservoir pressure cap is serviceable,
4) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
5) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

Replace the thermostat, if all above ok.
