Oiwa Garage Tech Note

"This is the 8-piece kit. Squeeze each hose cold to judge it - firm and springy is good, mushy or rock-hard is failing - and renew rusty clamps with the hose."

Frequently Asked Questions

Do I need to bleed the system after?

Yes. Refill and bleed the air out so the cooling system works and the engine does not overheat.

How do I check my radiator hoses?

Squeeze each hose cold - a good hose is firm and springy, while a mushy, swollen, or rock-hard hose is failing. Look for cracks and weeping at the ends and clamps.

Should I renew the clamps with the hose?

Yes - rusty clamps do not re-tension well and are the usual weep point, so fit fresh clamps with the hose.
