Guest WESTCORT Posted November 16, 2008 Share Posted November 16, 2008 My escort pinto engine runs at around 200-210*f is this too high? Its running slighty hotter i think with the 48DHLA (single) but its been like a year since ive had it running so cant remember what temp it ran at with standard 32/36. it got a cortina radiator standard fan and shroud. No electric fan or anything but wondering what the best way to cool it down would be if its running too hot.. Dont really want to shell out on a new radiator so is there any tricks to keep temps down a bit? have actually got an electric fan that i could put on with a thermoswitch. Could this be the way? Where can i get a thermoswitch from / link to installing one? but the electric fans stop having an effect after 50kph or so dont they? Should it replace my standard fan or shud i use both? Have heard of antifreeze/coolant shit you can put in that cools quicker than regular water? Not sure if its just another gimmick tho.. suggestions please? nice 1 EDIT: after discovering the wonders of the search button, it seems alot of support for water wetter? this could be just what im after, dont currently run antifreeze just water..

sentra Posted November 16, 2008 Share Posted November 16, 2008 all that shit does fuck all aye put a bighger one in / old one more passes or just cleaned etc 100 c is smokin for a car with a mechanical fan. check thermostats working if it randomly did it 1 Quote Link to comment Share on other sites More sharing options...
Hemi Posted November 16, 2008 Share Posted November 16, 2008 yea thats pretty freaking hot for a mech fan and like sentra siad check thermostat , never seen one jam shut but hey that could be the prob. and if it dont have one put one in cos it can cause huge flow problems Quote Link to comment Share on other sites More sharing options...

Unclejake Posted November 16, 2008 Share Posted November 16, 2008 I say it is running too lean in the fuel charge. Quote Link to comment Share on other sites More sharing options...
shizzl Posted November 16, 2008 Share Posted November 16, 2008 get radiator flushed,get engine tuned,change thermostat,run antifreeze,thermo fan. do skids. Quote Link to comment Share on other sites More sharing options...
Guest WESTCORT Posted November 16, 2008 Share Posted November 16, 2008 yup got headwork, ported + big valves. definatly not running lean.. Has been tuned and ive seen the air/fuel ratio of the dyno sheet. Could try flushing out the radiator again. havent done it for a while. anyone recomend some good shit to flush with? replaced thermostat when i rebuilt engine bout 5000ish k's ago. should i use a different thermostat perhaps? what temp thermo should i get? that is, if you can get them for different temps for pinto's. from memory it always ran at least 200*f with the 32/36. What should it be running at? what temps are other peeps pintos running at? Quote Link to comment Share on other sites More sharing options...
Gaz Posted November 16, 2008 Share Posted November 16, 2008 200°f is only 93°c Not that bad. Thats bout where mine used to run. Quote Link to comment Share on other sites More sharing options...
NewGuy Posted November 17, 2008 Share Posted November 17, 2008 200°f is only 93°cNot that bad. Thats bout where mine used to run. Yea i wouldn't be worried about it unless you have a Factory Gauge and Sender, go to a speed shop they usually have IR temp meter they can point at the motor, did mine for free only took 2 mins. 93 Degrees is the same as where my car is at idle. and a bit lower then cruising.

phtmbl Posted November 17, 2008 Share Posted November 17, 2008 you can get a thermostat with a lower opening temp which allows the water to flow sooner which in tern will cool it by a couple of degrees. 200f should be fine water under pressuse has a higher boiling point. Fan thermo switch are cheap to buy, they come in all temps, the easiest to install in a neg earth one as it one needs two wires one side of fan straight to pos on batt the other fan wire to the switch, If you know how to wire then you can get technical with fuses and relays but you dont need them.

forced Posted November 18, 2008 Share Posted November 18, 2008 200f should be fine water under pressuse has a higher boiling point.. Water doesn't boil til 212 deg at atmospheric pressure so what's the problem? Steve Quote Link to comment Share on other sites More sharing options...

xsspeed Posted November 19, 2008 Share Posted November 19, 2008 Most antifreeze brands also raise the boiling point. Water will boil at 100* C at sea level atmospheric pressure, regardless of being in a pot or what have you. I would suspect it would be slightly more in a cars cooling system because there would be some pressure (despite expansion tank) Quote Link to comment Share on other sites More sharing options...
forced Posted November 19, 2008 Share Posted November 19, 2008 I would suspect it would be slightly more in a cars cooling system because there would be some pressure (despite expansion tank) Well yeah, that's why there's a pressure cap.It raises the boiling point.

Steve Ok perhaps my subtle sarcasm was missed, yes there will be a higher boiling temp cos its under pressure, plain and simple, as a result I wouldnt be worried about the OP's water temps, but if he wanted to lower them he could as mentioned swap out the thermostat.

slipsittin Posted November 23, 2008 Share Posted November 23, 2008 On the pressure side you could raise the cap pressure to a 15psi one if your cooling system is in good nick. That will bring it down. I would run antifreeze/boil also. 93C is all good but a little higher for a manual fan I guess but the exhaust system plays alot with temperature when running modified engines. If its breathing everywhere but the exhaust it will be hotter Corey Quote Link to comment Share on other sites More sharing options...
Chrome_GT Posted December 19, 2008 Share Posted December 19, 2008 I wouldn't worry bout your operating temp as i've also seen 93° on alot of cars. If your still worried here's some thoughts: Thermostat change - My understanding is that a lower temped thermostat will only open sooner. Therefore it will take longer to get to 93°, but you will still get to 93° anyway. So changing thermostat will not change your final operating temperature, it'll just change how you get there. Other options -Fit an electric water pump of higher flow rate. I don't know the output of your mechanical pump but higher flow rates can help a bit. -Check radiator core for may be blocked or missing cooling fins. To recore your escort rad it'll cost about $200 -Check timing - you may be running engine hot by having too much retard in your timing. -Check fuel delivery - may be lean -Chenge to an electric fan which is more efficient at pulling air through. Common mod to old cars anyway for horsepower and to help them warm up. -Have experimented with water wetter, didn't make any difference -Try running less antifreeze. Antifreeze isn't as good as pure water at heat transfer. Pure water is optimal Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted December 20, 2008 Share Posted December 20, 2008 if i remember right at 0.9bar water boils at 115c 117c with correct mixture of quality antifreeze take your radiator to a radiator shop for cleaning cost me $60 last time and they will be able to tell you how blocked (if at all) it was so you know if you have other issues or not, they also do a better job than you can do with a bottle of rad flush and a hose pipe Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted December 20, 2008 Share Posted December 20, 2008 Is the rad a nice fit in the rad support panel? If air is able to go around the rad, it will. I've got a primo custon ally rad in my 1200, and I've packed the edges against the rad support panel with heavy foam lagging to prevent the air "bypassing" the rad. Also does you car have the sump sheild fitted? Might sound likre a daft question, But on many cars the sump sheild deflects air from passing directly under the motor which actually creates a low pressure area behind the radiator. This will promote air flow through the rad, and encourage cooling. how angry is your motor? I had a MK5 corty rad in my 1200, that was in decent nick. But it just wsn't big enought to keep my 1200 cool. Maybe try one from an L20B 910 bluebird if it will fit. BUT, get all the basics right 1st. Like every one has said, Take the rad to a rad shop get them to pull the tanks, and rod out all the cores. Drop your T/stat in a pot on the stove with a thermometer in it. Heat it up untill it opens and note at waht temprature is does. If it isn't the same temp that is has stamped on it, chuck it out and by an new one. I've seen $2000 dollars motors rooted 'cos they were too mean to buy a $20 T/stat. Your running a mech fan aye? Is the fan belt tight enough? might sound silly, but it wont help.......... My 2c.

forced Posted December 22, 2008 Share Posted December 22, 2008 A decent tune up (AFR and timing) is often a good cure for overheating. Steve Quote Link to comment Share on other sites More sharing options...
