overheating with trailer

[daddydarko]

It was almost 90 today and everytime I get off the freeway, I overheat and go into limp mode. This only happens with the trailer.

Have you tried taking off the rear splash pans as Lamonster did?

I haven't trailered in the heat yet, but so far so good. That seems kind of strange to only happen with trailer on. You need to get that taken care of before LA cause it could be a lot hotter for our ride.

EEK!!! That doesn't sound good. We want to pull a trailer too and I don't need any of that happening.

I am not familiar with this. Have a link?

Sounds like a voltage-drop, check your eletrical system when the trailer is attached.

As you know I've been cross country towing a trailer in the summer and thousands of miles in 100+ degrees and have never went into limp mode because of heat. Make sure you don't have an exuasht leak under the cowling, that will raise your temps.

Here's the links about the splash pans. I drop one to two bars when I remove these.

Here's what your temp bars read.

Discovered heating problems are due to trailer size. Can't risk burning up engine so headed home. More when I return.

How heavy and what size is your trailer?

Maybe your guns are blocking air that needs to flow into those holes and the trailer is just pushing things to the limit.

Also realize your shifting points will be different with the trailer - you may not be able to use 5th gear at all.

INCY down in Australia pulls a HUGE trailer and has not reported such problems. I think you must have a combination problem. Something is pushing your temps up and the trailer is taking it over the top.

Bummer - maybe removing those splash pans will help.

Keep us posted---- ride safe!

Something doesn't seem right. Is your fan coming on? I pull a trailer two up a lot and have no problem in hot weather even when the trailer is loaded to the gills, including stuff lashed to the top. I would suspect the fan is not coming on. If the fan is working properly you have some other things to check into based on the replies of others. Good Luck Hope this turns out to be something simple.

I will do some more investigating when I get home. I can't hear the fan (or anything for that matter) over the Tailgunner exhaust. The gun barrels block the same holes fog lights go into so it can't be that. Has to be trailer weight or maybe I've developed an exhaust issue in the last few hundred miles.

Take some white-out or some white tape and mark a couple of the fan blades---- then look down once you hit 5 bars and see if it's spinning. It's not something you're going to hear.

Could be fan fuse or relay. Hopefully one of those is the culpret!

Didin't think of it before but I assume you have checked your coolant level.

Any updates DD ??????

I don't have much going on this weekend--- could buzz over and give you a hand if you need it because I know you need to hit the road for DC soon!

Hopefully you got something figured out and are on your way already!

BAD RELAY SWITCH!

By some horrible coincidence, the fan relay switch went out when I hooked up the trailer so the fan was never kicking on. I swapped the headlight relay and it started working. Now I just need to find another relay switch.

Thanks, MM for the tip!

I found the relay number I was telling you about on the phone today.

You can pick one up at Autozone it's a Duralast 19271 41-5100 relay

I'm glad I was able to help!
