Mud in Radiator - Overheating! was created by ryan28
Hi all,
So 'Lee R D 30' and I had a blast at Slindon Safari in Sussex today at one of their pay and pay days.
On the way back though, both of our Jimny's started to get very hot and we had to keep pulling over to let them cool down. We noticed both radiators were pretty gummed up with baked on mud so pulled into a jet wash and blasted as much crap out of them as possible which seemed to improve things after a few attempts.
How do we avoid this happening again? Also is there anything I can spray on the rad to clear it out of mud or is it going to be a case of removing it and checking the fins?
Cheers
Ryan

The other option is to not go through muddy water deep enough to get into the radiator fins.
This is the dull answer I know but muddy water kills cars like the Jimny in other ways too, like the swivel seals are not designed to keep water out so it gets to your kingpin bearings also!

... and into the diffs if the breathers haven't had extensions fitted to them to keep them above the waterline
I avoid water and mud if possible.

Not going through the muddy water is a little unavoidable at times with some of these trails, and yea it's pretty fun!
Does the mesh over the grilles not restrict airflow a little?
Is it worth fitting some kind of under trays to stop the water from splashing up into the bay?

I like the idea of the mesh in the front grille. Job for next weekend I am thinking.

Wouldnt recommend getting the jet washer anywhere near the rad, I unintentially made that mistake and flattened half the ali fins in the rad effectively blocking it.

Muds a pain but kinda unavoidable if you go to the pay & play sites. I find it's not really the clumps of mud just the silt stirred up with vehicles constantly going through the water. It just dries on and hard to get off and really buggers the effectiveness of a small rad.
I found the best thing is a good spray with muc off stuff and then use a low pressure 12v pressure washer and loads of water through the rad fins before heading off to the road. It's a pain but I never found a proention. I don't tend to go to the P@P sites anymore but do occasionally do some more full on laning, often going through quite deep water and none of us have ever had a problem.
Someone once told me they kept a rad just for doing the P@P sites and just kept swapping, bit of work but not a bad idea, probably wouldn't take any longer than trying to give the rad a good clean in situ.

I mean never had a problem with mud in deep water, I should mention everyone has snorkels and breather pipes to diffs, box and tbox, otherwise yup deep water is a bad idea.
