why does my 95 gt mustang gets hot and cold it goes up and down?

Question

EVERY TIME I STEP ON GAS HARD WHEN I GET TO 6,000 RPM IT MAKES A LITTLE NOISE AND MY TEMPERTURE RISES BUT THEN WHEN I DRIVE NORMAL IT COOLS DOWN WHY IS THAT

Answer 1

sounds like your timing is too advanced does it ping at that high of a rpm??? if so your fuel is detanating...aka spark knock..set it at 13 with premium gas 10 with regular...i'll bet thats whats wrong with it..and if it's a stock mustang it stops pulling at 5600..no need to take it to 6000 rpm...and your pcm is set at 6100 for your rev limiter..plus it is a hydralic roller motor...taking that high only floats the valves

Answer 2

JAREAD may be correct. That what it seem like. The Engine generates a lot of heat. 5,000 F type stuff in the cylinders. Check that Belt to be sure, odds are it would squeal on you. Your Thermostat may not be responding quick enough for the acceleration and Temperature rise. May try a real good one and not stock. You do need it or the Computer go into a loop circuit, thinking the engine cold and will Flood with fuel when you Idle.

Answer 3

There are one or two possible causes for your problem. The noise may be caused by a slipping fan belt.

The fan belt tension is not tight enough and the slipping is impairing the normal flow of water in your cooling system. That is what I would check first, It is the most likely cause of your problem.

hope this helps:

i circulate to anticipate you place the intake clear out interior the engine bay. they do no longer likely paintings all that properly. the only actual way you notice a overall performance strengthen is once you get the intake which you feed in the process the factor wall decrease than the fender. in case you like much extra appropriate overall performance, you eliminate the wheel properly and installation a ninety degree attitude cover around the cone clear out and you will strengthen your capacity band interior the better rpm region. the only difficulty with having the intake feed below the fender without the wheel properly is you disclose some wires, vaccum line sensors, and you cant stress interior the rain for too long or you will suck up too lots water. you have got a water injected motor vehicle in case you stress in easy rain and make some serious capacity yet too lots water might have you ever bend a valve and/or flood the motor vehicle. Its the way I actual have my ninety 9 cobra setup and that i holiday jointly with 02 ws6 trans ams and beat them interior the rain!!! i've got carried out it so i comprehend!!!

Answer 5

Another alternative is that faster RPM creates higher PSI in your coolant system. Might consider changing your thermostat.
