hey guys i just did a body lift on my 93 pickup and now the truck overheats i was like hmm maybe rattling the rad around clogged it because the rad is rusty inside and the rad was hot at the top and cold right in the middle. so i change the rad and still it goes right to red after a few mins and i shut it off fast. also the truck idles like at 1500 to 2000 rpm fast like it has a loose vacuum line at idle. my buddy was thinking maybe the ecm is shot because it overheats and idles super rough. the truck ran like a champ before the body lift.i dont see how a body lift would make it overheat. my friend will ask his mech teacher tomorrow for me. im so stumped right now and dont want to tow to a mech.

 

well the rad should be hot at the top... its where the hot coolant goes into the radiator. Is one of your hoses by any chance kinked? Just assuming that since the radiator is attached to the chassis, and the motor is attached to the frame, when you do a BL, you need to change your hoses to compensate for the inch you gained vertically

 

How tall a lift?

Did you relocate the radiator with the body lift?

i stuck in the drop brackets. i did a 3inch body. on the other hand i got dope 33x12.50 superswamper tsls i think for free with good tread. tommorow im going to change the thermostat and check for a loose vacuum house but i checked most of them. it seems like i have a huge leak.

 

You dident take your fan shroud off did you?

 

Make sure you burt all of the air out of the cooling system... your heater core is 3" higher then the rad now. I had a tuff time getting all the air out of mine (2" BL)... ended up puting in a valve in one of the heater lines and backfilling it while the engine was cold.

 

Try this: Drain the coolant. Take the upper heater hose off, and fill the system until water pours out of the outlet for the heater core, and the hose you detached. Reattach the hose, and fill the rest of the system. Park on an incline, or jack up the front of the truck as well. You just have an air in the system, and its not circulating out. Thats what the high idle is from too, since the coolant temp sensor is searching for coolant thats not there.

 

both right on the money saved it to pass on later...

 

If you raised the body and the radiator and are still using the engine's fan you will effect / lose air flow across the radiator. If you did not raise the radiator you are probably blocking radiator air flow. Solution: Raise radiator and install a high output electric cooling fan.

 

do it!

 

Actually you want to lower the radiator (and the OP said he did this). The radiator is mounted to the body and raises with the body lift. Lowering the radiator re-aligns it with the engine mounted fan.

 

i fixed the problem. i emptied the rad. took out the thermostat,put cover back on. filled rad, started the engine and ran it for about 10 mins and the weird idle was gone. after ten mins i shut off truck, put the thermostat back in and filled up the rad again and the problem was solved. thanks for all of the replys guys

 

May I be the first to say.. Pics or it didnt happen

 

ok lol. i still have to lift the box i broke 3 bolts on one side and the other one is like sccrewed so im gonna torch it off tommorow. and im too lazy to extend the shifter. i like the sporty look haha

 

Haha, you lazy bastard

Do it right! The shifter would bug the hell outa me. with the extensions it shifts like a damn dump truck... Mile long throws I love it!!!

 

haha the throws on my dodge were superlong more than on a dump truck. im just gonna bend it forward or just relocate the shifter boot or plate. im just driving with no shifter boot or plate lol. that stupid lift took me like 4 times longer than i had imagined.

 

Mine streched over 3 days!!

waiting for a new cab bushing, waiting for welder, and doing it in the pouring rain.... yay!

 

i got soaked the other night changing the rad. at least u got help i did mine alone. its been like 10 hrs total. but i spent so much time cuz of the overheating problem.



damn found on road dead 6 inch suspension and 3 body in front on 35's
