Question 327 Running Hot!

Hey guys I posted about this a month ago and with your suggestions I have done the following: new high volume water pump, high flow 180 thermostat, moved temp. sending unit to the top of intake, fan correct inside of shroud, fan is stock type looking but heavy duty aftermarket 18" with aluminum blades, correct coolant concoction with water wetter added, new radiator cap, replaced new green line stewart warner gauge and sending unit with new set-------Still according to the gauge its running at 215 - 225. Then I bought an ir (raytec) temp. tool and everywhere I check, thermostat housing, radiator, hose out of thermostat, etc. I don't get a reading over 185! Then I drained out about a quart of coolant and replaced it with a quart of water to dilute it some (it was 50/50) and left the top of the radiator off so I could check for bubbles and watch the water in the radiator so I could see the water ripping through when the thermostat opened but the water never started ripping through. It just slowy, very slowly moves when the water warms but my gauge is showing the temp at 215-225, should'nt the water be ripping through if that was the temp. because my thermostat would be fully opened at that point? But even more screwy is when I put the lazer in the hot water of the radiator it only measures like 150! Is it possible I have a plugged radiator because the water is not ripping through it and another bad gauge also? Sorry I was long winded but I think I've given enough detail for someone to help out. Thanks.

Re: 327 Running Hot!

i was working on a range rover the other day with the exact problem i bought 3 temp senders for the truck the temp in the truck was 245 the rayteck said 205 on the thermostate housing. the thermostate was 195. the truck didn't seem overly hot not boiling over. i bought a sender from dealer problem over. from your descripsion you gauge is or sender is not correct. the flow of coolant threw capmay be slow depending on still or flow of radiator. good luck.

Re: 327 Running Hot!

Thanks for your reply Anthony, I was thinking that but it is the 2nd one I bought and it is reading the same as the first one. Maybe I'll take it out and test it in boiling water. If it is off the 25 degrees or so I think it is then I'll make sure and let every one know. These are the new green line electric gauges Stewart Warner just came out with. They are repro's of the old 60 & 70 style.

Re: 327 Running Hot!

I had a similar problem with the ole 327. She ran at 210 when I got er. I did a few of the things you did. Not much of a change. Then I installed a new radiator and problem solved. 185 deg.

Re: 327 Running Hot!

if the water isn't flowing properly it is most likely a plugged up radiator. check it for build up or take it to a shop and have them check it for you.

Re: 327 Running Hot!

yup, radiator is plug or at least the volume running through it is being restricted.
