ok so i drive my car normally as a everyday driver but every once in awhile ill go sliding. when i drive the car normally it overheat to about 75% sometimes and also when im sliding. is that normal?

 

What year and what kind of car?

Here is some general RX-7 cooling troubleshooting:

Its a 1988 Gxl.

 

What is sliding, by the way?

At any rate, start with the link I posted and go through each aspect of the cooling system.

It sounds like the car overheats constantly, which points to a water pump failure.

 

i think he's referring to drifting.

 

Arron yeah i went threw it. I replaced the hosing and installed a cool intake. So it's good now. And Yeah drifting.

 

By cool intake do you mean cold air intake? Rad hoses not holding pressure i could see causing some temperature increase, id expect to see some coolant on the ground though. But a slightly cooler intake fixing a 75% reading on the temp gauge? I think im probably missing something here

 

My engine only has 118k miles on it. i dont think i need a rebuild yet.

 

i doubt it and the reason is bc when it started becoming a hotter climate then it started over heating. so maybe i need different oil? idk. but ill check what you said RE MAN... better to be safe them sorry yaknoo

 

Re Man makes absolutely no sense so I'd ignore what he was saying for now...

 

Oh... aha um ight ty man. <3 was getting confused off what he was saying too...

 

focus on what aaron was suggesting.

 

Ok so replaced the water pump with my mechanic and drove it around a bit and so far so good. Stayed 50% the whole time. My mechanic said the water wasn't flowing enough. So yeah. Tyvm guys.

 

Firstly, I got rid of your posts b/c they were poorly written, confusing and didn't make any sense. I suggest you read the rules stickied in these forums to get up to speed on how the forum works and what passes for useful posts and what passes for what we consider "post whoring". I really don't understand why you feel the need to create 4 separate posts in 4 minutes with half a thought in each post...


Secondly, I didn't tell the OP anything or offer any advice other than to listen to Aaron who actually knows what he is talking about and can explain it in a form of English that most people understand. I have no idea why you would even say that I don't know what I'm talking about since I didn't offer any info.


Thirdly, your post looks like it was written by someone who is barely literate. I sincerely apologize if you are indeed illiterate and suggest that you go get some further education to remedy the situation. When you are on a forum and written language is how one communicates, then you should try and do a better job of it if you want to try and be helpful.

 

I am just throwing this out there. Isn't one of the major weaknesses of the Rotary design that it heats up a lot faster than conventional piston engines. Enough so that the stock radiator has a tough time keeping up with demand in hotter climates?

I would be interested to know what the problem is when you find out for sure Rotary9196

 

to keep any water cooled engine cool, coolant needs to flow efficiently thru the block. in my experience, overheating issues usually stem from either a failing thermostat, or a radiator not flowing as it should. rad repair shops, at lease the one i used to work at, have a way to flow test rads. and it's so many gallons per minute. the easiest way to test it urself is to remove it from the car and insert a garden hose in where the top hose connects. run the pressure up til the water flows down thru the rad but not over flowing out the filler neck. this will give u a good indication how well water flows thru the rad. unless the impeller in the water pump is completely rusted away, and i have actually seen this, they usually don't cause overheating. but if it made a difference in ur case then great. now outside of bad coolant seals causing steam from the exhaust, i've never had it actually cause one to overheat. also, if the cooling system hasn't been kept up in it's life time, there could be scale/corrosion buildup in the block causing flow restriction. if this is the case, then the whole system will need to be flushed out, which could also help the flow rate of the rad.

 

The problem for me was the water pump. My car is now not overheating. In total to do this. I got a new water pump. Got a better cool air intake And replaced the hosing.
